Introduction2.

General about DMS 600 software2.1.

MicroSCADA Pro Distribution Management System DMS 600 4.3 (DMS 600) is a newversion of Open++ Opera software version 3.3 with extended functionality. DMS 600functionality is very deeply integrated to MicroSCADA Pro Control System SYS 600version 9.x (SYS 600). Most of the functionality can be used also with MicroSCADASYS 500 version 8.4.2, 8.4.3, 8.4.4 or 8.4.5.

The abbreviation SYS 600 is used only when the topic is validonly for SYS 600. Abbreviation MicroSCADA is used whenthe topic is valid for both SYS 500 and SYS 600.

DMS 600 is a geographical distribution network management system (DMS). The soft-ware extends traditional SCADA capabilities by providing geographically based networkviews. DMS 600 (Base) package provides network component data management andnetwork modeling to provide network overview and topological coloring to see the net-work's state. In addition, DMS 600 has many optional modules with advanced functions.DMS 600 can be used with MicroSCADA, without SCADA or with other SCADA sys-tems using OPC Data Access interface. The software has been designed to assist theoperation's personnel of electric companies in monitoring and operating their networks.

Both raster and vector based maps can be used as backgrounds for the network window.It is also possible to create and use schematic network views, instead of geographicallybased network presentations and maps.

The software runs on PCs using MS Windows operating systems. Only 32 bit versionsof operating systems are officially tested and supported.

Additional (regional) servers can be used to store network data to keep the start up timereasonable in low speed LAN/WAN networks. MS SQL Server, Oracle or MS Accesscan be used as database for DMS 600. Also other database servers can be used if theysupport the required features of a DMS 600 database.

The graphics-based user interface of DMS 600 is unambiguous and the standard Windows‘look and feel’, together with the online help, makes it easy to learn.

General about DMS 600 Workstation2.2.

The DMS 600 system consists of three programs for users: DMS 600 Network Editor(DMS 600 NE), DMS 600 Server Application (DMS 600 SA) and DMS 600 Workstation(DMS 600 WS). The architecture of the DMS 600 system is described in more detail inSystem Administration. DMS 600 Workstation (DMS 600 WS) is a program for the

17


Operation Manual

operative personnel of electric companies to monitor and operate their medium and lowvoltage distribution networks.

The program contains the following functions:• Alarming• Network topology management• Network analysis including power flow and fault current calculations together with

protection analysis• Operational simulations• Fault location based on fault distance calculation and fault detector data• Restoration• Switching planning• Outage data management• Field crew management• Load estimation• Customer service• Database analysis• Document archive and• Map printing

The functional content of the system depends on the licenses, sublicenses and definitionof optional functions (for more information about installing DMS 600, see InstallationManual and System Administration).

The basis of DMS 600 WS is a distribution network database managed by DMS 600 NEand real time process data from MicroSCADA. You can control actions using Micro-SCADA graphics, or you can open SYS 600 control dialogs directly from DMS 600WS. You have control rights to an opened control dialog only if your username andpassword in the DMS 600 match with the user information in SYS 600 and if you areauthorized to control the selected switch.

Open++ Integra is an information management system for ageographical distribution network. It can be used to replaceDMS 600 NE in a DMS 600 distribution management system.

Operation Manual

Software release updates3.

New features and functions in DMS 600 4.33.1.

Inverse time curves

An inverse curve (or inverse time curve) is a curve that is used to define an operationtime of a protection relay. The input is typically a relation between set current value(Iset) and measured fault current (I) => ( I / Iset ). Inverse time curves are defined withvarious equations. Some of them are defined in international standards (IEC/IEEE) andsome are industrial de facto standards (IAC) or manufacturer-specific curves (RI, RD).

Extended Trouble Call Management

Trouble Call Management is used to handle customer complaints and fault notifications.Trouble Call Management uses the Disturbance Data Form to collect information aboutthe faults, such as the nature and location of the fault. The Trouble Call Managementsublicense is required to enable this feature.

AMR extensions

MicroSCADA Pro DMS 600 can be integrated into AMM/AMR (Automatic MeterManagement / Automatic Meter Reading) systems. This enables using the communicationand device infrastructure created mainly for energy metering to also remotely monitorthe low voltage networks. The monitoring can include receiving spontaneous alarmsregarding network faults and voltage violations, as well as reading measurement valueswhen exact data is needed.

DMS 600 combines information from several customer points and can inference, forexample, a probably blown fuse in the LV network. DMS 600 uses OPC DA client toconnect to AMR system and, thus can receive events close to real-time.

Improved fault management

The fault management includes the following improvements:

• Fault handling areas can be used to allow automatic fault location only in selectedareas. The areas can be defined separately for each switching device.

• Possibility to set the fault status.• Fault repairing time estimate can be set directly from the fault list without the tele-

phone answering machine functionality.• General information window shows duration of the fault, number of unsupplied

customers per fault even without fault location or opening the switching plan.

19


Operation Manual

• The fault distance in meters is available from some protection devices. The distancecan be used instead or parallel to reactance and fault current in the fault location.

• Possibility to change the intervals for reading outage data and for unsupplied MVLVsubstation data.

• Possibility to create a fault for areas fed by a disconnector or a MV fuse.

OPC interface extension

The OPC interface extension includes the following new functionalities:

• The system administrator is able to configure the OPC item name suffixes.• The DMS 600 SA subscribes the TRIGGER OPC items for each circuit breaker in

order to initialize the fault creation functionality.• All available OPC items constituting faults are subscribed. This function is performed

right after the TRIGGER OPC item has been activated. For the OPC items to beavailable, the OPC item name must be configured, and the process object must becreated in SYS 600.

• Possibility to create a new fault for further processing.• The subscribed OPC items are reset so that they can be reused in the next fault case.• A notification of changed OPC configuration. DMS 600 SA reflects the changes in

the OPC configuration without the need to restart it.• Integrating manual switches to SYS 600 offers a practical way to display also

switching operations of manually operated switches in the SYS 600 event list.

Improved switching planning

The following improvements have been made for switching planning:

• Fully supported MV fuses. The MV fuses can be handled in the same way asmanually controlled disconnectors.

• The breaking capacity of a switch is checked against the calculated load currentwhen opening a switch.

• Fully supported CBs with trucks.• Locking switches open from the control dialog is supported.

Transformer model changes

The Transformer model is renewed to better meet the needs of three winding transformers.The data forms of the MV/LV transformer and primary transformer are renewed. Also,the transformer series functionality has been made easier to use.

20


Operation Manual

Network planning

With the network planning feature of DMS 600 NE the user can design the networkbefore adding it to the network database. It enables comparing the alternative networkstructures, monitoring investment and interruption costs, as well as making calculationsbased on suggested network components.

DXF import for network data

DXF import for network data, initially exported from 3rd party GIS system, is nowpresent in the DMS 600 Network Editor's basic functionality.

The user is able to define the DXF layers, line routes and symbol blocks to be importedinto the DMS 600 database. All the desired MV/LV the line sections and nodes areimported directly into DMS 600 network model.

In addition to DXF format, also the AutoCAD's DWG format is able to use in DXFimport function. The new DMS 600 DXF Import Tool, launched from NE, uses OpenDesign Alliance's (ODA) DWGdirect™ library in reading DXF and DWG formats.


Extended automatic fault isolation and restoration

In addition to control actions, the generated sequence file includes the circuit breakersto be checked. The information can be used to check that the circuit breaker feeding theback-up connection remains closed. If that circuit breaker is opened due to relay trip,the restoration will be cancelled.

Switch state updates with modified time and possibility to correcttimes in event list

The switch control dialog for manual devices includes a control that gives the real timewhen the switch was operated. In addition, the event time can be changed in the DMS600 event list afterwards. This enables, for example, the creation of outage reports withcorrected event times.

Relational database servers

DMS 600 can use relational database servers (such as MS SQL Server and Oracle) insteadof MS Access database to store data. The connection to a database is made using ODBCdata source name (DSN) definitions. MS Access databases without DSN definitions are

21


Operation Manual

still supported. For Hot Stand By systems, two relational database servers with a replic-ation feature are recommended instead of Access databases.

Parallel network views

It is possible to select the used network view independently in each program instance(workstation). The user has the possibility to create a new view by moving and hidingnodes and lines in the main view without overwriting already existing data. For example,a parallel schematic diagram can be created (orthogonal schema) to make networkoperation clear and effective but exact locations of objects can be viewed on a map usinga geographic view. All views can use the real time network coloring to show the stateof the network as before.

Switch state quality (status) separated from switch state

Separate symbols can be defined for uncertain switch states (open, uncertain or closed,uncertain). These symbols are used when the switch state is known in the SCADAdatabase but quality is uncertain. In the OPC interface this means that OPC qualityQUALITY_UNCERTAIN used, and in the SCIL API interface the status values 1, 2 or3 are used. The OPC quality QUALITY_BAD or status 10 (not sampled) cause the stateof the switch to be shown as error, as before. The user can define if uncertain state willcause network coloring to use unknown color. Error state will always cause unknowncoloring.

Manual state update for switches connected to SCADA

Disconnectors and circuit breakers that normally reserve the state from SCADA can bemoved to manual state update in DMS 600. This can be used as a temporary solution,for example, to see known state in DMS 600 if communication to station is broken andSCADA is not showing the known state. There are separate symbol definitions for closedand open, manually updatable switches.

Distribution Contingency analysis

The user can define sequences that can be used to check if the system is capable ofhandling known fault situations with present loads. For example, the sequence can checkwhether there are acceptable back-up feeds when some main transformers have to beswitched off. The power of generators and motors can be changed in the study, too.

22


Operation Manual

Power values for motors and generators

Real time measurement values from SCADA can be linked to motors and generators sothat the load flow calculation in state monitoring mode can use measured values. In thesimulations the user of WS can change the values with simulation dialogs.

IED (relay) modeling

For documentation purposes the network database can include data for any kinds ofprotection and control devices. For example, distance and differential protection deviceswith their properties and setting values data can be added. The user can define additionaldata fields for any protection devices.

LIB 500 not required anymore

DMS 600 can be used with SYS 600 without installing LIB 500. The tools that wereearlier available only when also LIB 500 was installed are now available without a LIB500 installation.

Improved fault management

• Switching to another fault instance is faster than before since all existing faults arein main memory.

• Operation is faster when there are several unrepaired faults since switch state changesare not anymore stored to each fault file. For reporting the switch state changes areread from the event log instead of the fault files.

• The Fault Management dialog is resizable. For example, the list presentation ofpresent faults can be increased so that more information can be seen at the sametime.

• Extreme conditions switch is added. When there are a lot of simultaneous faults andlots of switch state changes, the operation of the system can be changed by pressingone button so that the screen update interval is increased and automatic load flowafter changes is switched off.

Customer service points in MV network

A customer service point can be added to the MV network to represent a so called MVcustomer that has their own transformers. The load or energy data can be given for aservice point so that the service point will be included in the load flow calculation withoutmodeling MV/LV transformers owned by the customer.

23


Operation Manual

Generic OPC DA client

The DMS 600 OPC DA client can be used with any compatible OPC DA server to getreal time switch states and measurements to DMS. However, alarm indications can beobtained with OPC DA only from MicroSCADA Pro SYS 600 by using SYS 600 specificalarm attributes.

Extended tracing functionality

The user has a possibility to view all switching devices along the selected trace in thetracing order. The list shows the type and the existing state of each switch. Through thisdialog a selected switch can be located and it’s switching state can be changed. If thestate of any of the switches in the list is changed, the dialog becomes outdated and thetrace coloring will be cancelled and the dialog closed. The network window can bezoomed to show all line sections included in the trace to easily see how far the tracecontinues in the network. This zoom function is available in same shortcut menu wheretrace functions are located.

Network presentation enhancements

A radial network fed by a circuit breaker but not having any loads connected can bepresented with a special no-load color. This helps the user to see which circuit breakerscan be opened without harm. There is a different symbol for unsupplied primary trans-formers. This clarifies the network view and switching operations on substations. Adashed line can be used for coloring an unsupplied (no voltage) network.

Operation Manual

User and region management4.

General about user and region management4.1.

Login and logout functions in DMS 600 WS are based on user identifiers (username andpassword).

Network data can be divided into several regions according to primary transformers andgenerators. The total amount of primary transformers and generators defines the maximumnumber of regions.

User right levels can be defined for each region separately. User identifiers, regions anduser levels for regions are defined by the administrator. For more information aboutregion and user level management, see System Administration. After a successful login,network windows show the medium voltage network which associates with regions thatthe user has rights to view. The program operates according to the rights given to theuser that is logged in.

Logoff mode4.2.

If login is quitted or failed during start up, DMS 600 WS will return to the logoff mode.DMS 600 WS also returns to the logoff mode after you select File > Logoff. You canlogin with the menu command File > Login.

DMS 600 software has very strictly restricted functions in the logoff mode. The operationof DMS 600 WS in the logoff mode is restricted to the following:• Viewing of the medium voltage network switching state• Viewing of the fault list (fault location is not working)• Zooming and panning of the network window• Login to the software• Most menu commands are disabled• Restricted closing of the DMS 600 WS.

If you close DMS 600 WS in the logoff mode, user logoff isperformed in the optionally associated MicroSCADA monitorwindow. Afterwards the monitor can be used normally butbefore any control actions can be done you must login toMicroSCADA again by selecting Main > Login from theMicroSCADA menu.

User level rights4.3.

DMS 600 contains five user levels with different rights:

The user name "Admin" always has all rights for every region and every action regardlessof later definitions.

The user needs control rights, for example, to carry out switching operations.

The user level with no viewing rights can be used to prevent the user from viewing thenetwork of a special region.

If a user does not have sufficient rights to perform an action,the action will be disabled in the user interface but the usercan still see it.

Regions4.4.

DMS 600 software uses three different types of regions:• Dynamic region contains all supplied network components of the primary transformer

or generator in the current switching state. The content of a region changes dynam-ically according to the switching state. Any unsupplied section of the network is notincluded in the region.

• Normal region contains all network components in the normal switching state (alsothe unsupplied network components). The content of normal region is saved auto-matically when the normal switching state is saved in DMS 600 WS (for moreinformation about saving normal switching state, see 8.4.2, Updating normalswitching state).

• Extra regions can be defined to contain freely chosen network components andnodes. This makes it possible, for example, to control the same switching devicefrom the control rooms of several regions.

To carry out a switching operation, the user needs the controlrights to only one region type (dynamic, normal or extraregion).

27


Operation Manual

Starting DMS 600 WS5.

Starting DMS 600 WS5.1.

DMS 600 WS is normally started from SYS 600 menu Tools > DMS 600 Workstation(Open++ Opera > OperaWS in older MicroSCADA versions). SYS 600 logininformation is used automatically. If the username and password entered in SYS 600login do not match, the username and the password are required (for more informationabout user levels, see System Administration). Last successful login username is proposedin the Login window.

DMS 600 WS can also be started by double-clicking the DMS 600 WS icon or the filenamed OperaWS.exe in file manager. In this case, the integration to MicroSCADA isdefective.

DMS 600 WS can be started also from the start menu using the program group addedduring installation (for more information about the program group, see InstallationManual. However, to be able to open classic monitor graphics from DMS 600 WS, theprogram must be started from the classic monitor menu. The way the Monitor Prographics are opened is not dependent on how DMS 600 WS is started.

If DMS 600 WS is started but the program is in the logoff state, select File > Login.

During the start up process from MicroSCADA, DMS 600 WS:1. Tests the connection to the primary fileserver. If the primary fileserver is disconnec-

ted, DMS 600 WS tests the connection to the secondary fileserver. If the secondaryfileserver is not responding, an error message is displayed and DMS 600 WS shutsdown.

2. Tests the connection to the MicroSCADA system. If the connection is OK, DMS600 WS reads the real time status of the switches (from the DMS 600 database)obtained from MicroSCADA via DMS 600 SA or OPC Data Access. If the connec-tion to MicroSCADA is not in use, a message is displayed and the last statuses ofthe switches are read from the DMS 600 database. While disconnected, changes inthe statuses of the switches are saved to the DMS 600 database. After reconnectingto MicroSCADA, the real time statuses of the switches are obtained by DMS 600SA or OPC Data Access.

3. Loads the medium voltage distribution network data from the binary network fileand the temporary network data from the temporary network file.

4. Creates a medium voltage distribution network topology from the distribution net-work data, temporary network data and the statuses of the switches.

5. Performs the network and protection analysis of the present network topology.6. Represents the medium voltage distribution network, colored according to the

switching state of the feeders in the network window and according to the voltage

drops in the auxiliary network window (the default views can be changed duringprojecting).

7. Checks for and announces if any new fault has occurred while disconnected. If newunrepaired faults are found, DMS 600 WS asks if the faults should be displayed onthe screen.

Upon completing start up, DMS 600 WS is in State Monitoring Mode. If login is canceledor failed software starts in logoff mode (for more information about logoff mode, see4.2, Logoff mode). During the Simulation Mode or Switching Planning Mode, the ESCkey returns DMS 600 WS to this mode.

To log off, select File > Logoff and to close the software, select File > Exit.

User interface6.

General about user interface6.1.

In the user interface data is represented in dialog boxes, lists, graphics-based networkwindows and diagrams, geographic maps, and colors. You can select functions frommenus and submenus that are controlled with the mouse and keyboard, or with toolbarbuttons. The dialog boxes contain scrolling bars, list boxes, check boxes, option buttons,command buttons, and other elements similar to MS Windows user interfaces.

The user interface of DMS 600 WS consists of title bar, menu, toolbar, status bar, andmain and auxiliary network windows showing the distribution network. The toolbar canbe hidden with the Window > Toolbar command . If not restricted by the administrator,the Window > Arrange Windows command arranges the windows back to their presetplaces.

If the pointer is held for a moment over a toolbar button, a description of the functionpops up near the button. At the same time, text describing the function is displayed onthe status bar.

To display a shortcut menu, right-click the main network window. The menu contentdepends on the position of the mouse.

To open the Print shortcut menu, right-click any list window. The command opens aseparate window for saving or printing the list data. The width of columns can be changedin the preview window. The font used in printing is the defined Base font (for moreinformation about font definitions, see 7.3.3, User interface fonts settings).

Workstation status bar6.2.

The DMS 600 workstation status bar is divided into three separate panes. The first paneis dedicated to application messages and function descriptions. The second pane showsthe active operation mode (for more information, see 8.2, Selecting operational modes).The third pane shows the main status of application connections. This value is a combin-ation of several options based on the environment configuration. Combinations wherethe value is 'Online' are presented in the following table. In all other cases, the status textis 'Offline', and the indicator color is red. A yellow indicator color is used when someof the available communication interfaces are not in ‘Online’ state.

The outlook and location of map material can be set workstation-specifically in everyDMS 600 software. The background maps can also be disabled via the Settings> Maps> Outlook command (for more information about outlook and storage of the backgroundmaps, see 7.9.2, Outlook of background maps and 7.9.3, Storage location of backgroundmaps).

Free database layout can be set network component or object-specifically using thefunctions in the appropriate data form. For more information about free data form layout,see 8.7.4, Content of free data forms.

The administrator can specify the symbols, line colors and background color used in thenetwork windows and diagrams. DMS 600 software uses geographic maps as the back-ground for the distribution network. The administrator can set background map usage.For more information about administrator settings, see System Administration. The sizeand location of most windows can be changed. The state of the windows (visibility, sizeand location) is saved when quitting the program.

Network windows6.4.

General about network windows6.4.1.

DMS 600 represents the distribution network in two network windows. The auxiliarynetwork window always shows the whole network or selected region(s). The view of alow voltage network with a very accurate zoom is an exception. In that case, the auxiliarynetwork window shows a more general view from the appropriate low voltage network.The main network window shows a specific area of the network in more detail. The areacovered by the main network window is shown as a rectangle in the auxiliary networkwindow. Normally the medium voltage network is visible in network windows. Lowvoltage networks are always read separately to the memory.

31


Operation Manual

If you hold the mouse cursor for a moment over a network node or a line section in themain network window, a tool tip is opened presenting information about the node or linesection, and real and reactive powers defined by the network analysis.

Controlling the views in network windows6.4.2.

Network windows can be zoomed and panned. If not restricted by the administrator, thesize and location of network windows can be changed. This information is saved duringthe shutdown of the program.

Coloring of network windows6.4.4.

The information displayed in the two network windows can be chosen using the submenusin the View > Coloring menu. The functions focus on the active network window.

The colors represent different kinds of information. The colors of network lines aredefined in DMS 600 NE. It is possible to define fixed and pre-selected pen colors andpen widths for primary transformers and for the MV-feeders. The fixed colors areavailable parallel to dynamically changing network colors. When presenting feedertopology (View > Coloring > Topology by Feeders), adjacent feeders are colored witha separate color so that an open switch is easy to find. Cold lines, lines in looped connec-tions, earthed and uncertain/unknown lines are presented with separate colors. Maintransformer topology (View > Coloring > Topology by Primary Transformers) andconductor types according to predefined classification (View > Coloring > Line Types)are presented. MV voltage levels (View > Coloring > Voltage levels) can be presentedwith different colors. An extra window with color information is opened onto the screenif needed.

The symbols of MV/LV transformers and substations (diagrams) can be drawn with thedefined feeder color regardless of the selected coloring option. The color of symbols,including subsymbols and special symbols, is changed to match the feeder color. Youcan turn this coloring option on and off by selecting View > Coloring > Use FeederColors For MV/LV Substations.

You can switch between fixed and dynamic coloring modes by clicking View > Coloring> Use Fixed Colors or by clicking the Fix button in the toolbar.

The function Use Fixed Colors is common for the coloring modes Topology by PrimaryTransformers and Topology by Feeders. It is common also for the network windows.When Use Fixed Colors is selected, a line color legend appears to show the definedcolors for the Feeders / Primary Transformers that are visible in the primary networkwindow.

5. Define the LV network protection to be analyzed against Fault current/fuse orOperation time based by selecting the appropriate option.

6. If Operation time based analysis is checked, define the maximum operation timefor the fuse.

If you select the Fault current/fuse option, the protection analysis of LV networks isperformed using the percentage ratio between the short-circuit current and the fusenominal current multiplied by 2.5 (if the fuse nominal current is <63 A) or by 3 (if thefuse nominal current is > 63 A).

If you selcet the Operation time based option, the analysis of LV networks is performedusing the ratio between the given maximum operation time for the fuse and the averagemelting time of the fuse with the short-circuit current. The melting times of the LV net-work fuses are based on the LV network fuse melting time diagram.

Alarms, warnings, notices and events8.13.

General about alarms, warnings, notices and events8.13.1.

Alarms and warnings are generated in DMS 600 WS based on network topology, networkand protection analysis and fault location. The presentation of MicroSCADA alarms andwarnings is in use if the General Extensions license with the Alarms Presentation subli-cense is in use, and the functionality has been selected.

DMS 600 WS alarms and warnings are presented using colors in the network windowsand inserting text to notices and an event list. MicroSCADA alarms and warnings arepresented with user-defined symbols in network windows and changes in object alarmstates presented by inserting text to an event list.

Events are presented using the event list. The contents of the event list is stored to per-manent log files. Earlier events can be reloaded in DMS 600 WS. Notices are not stored.

MicroSCADA alarms8.13.2.

This chapter does not apply to the DMS 600 (Base) license.The General Extensions license with the Alarms Presentationsublicense is required for MicroSCADA alarms.

The alarms of the following object types are transferred from MicroSCADA to DMS600 WS:• Disconnector• Primary substation• Circuit breaker• Measurement• Fault detector.

MeaningAlarm Type

The value of the object is currently alarming andthe alarm information has been acknowledged.

Alarm active - acknowledged

The value of the object is currently warning. Thisalarm type in DMS 600 WS contains both thelow and high warnings of MicroSCADA.

Warning

The value of the object is not warning or alarm-ing.

No alarm or warning

It is possible to define symbols for the first four alarm/warning types in the table. Formore information about symbol definition, see System Administration.

If the primary substation is drawn using a substation symbol, the alarm symbol commonfor all substation components is used. If the substation has several objects having alarmsor warnings, the alarm symbol for the whole substation is the most critical and it usesthe criticality order.

Unacknowledged alarming primary substations, circuit breakers, disconnectors, faultdetectors and measurements can blink in defined colors. The symbol is the same that isused for an unalarming object, for example, the symbol used for an open circuit breakerin the current zoom level. The symbol is blinking switching between the defined blinkingalarm color and the normal symbol color. The interval for the color switching is 1 second.Blinking can also be disabled from all workstations, for more information about setting,see System Administration.

MicroSCADA alarms are also visible in DMS 600's events list, which means that theyare stored into a permanent log.

Simulation of historical events8.14.

General about historical events8.14.1.

Any switch state change event can be found from the saved event history log files. Withthe step-by-step proceeding list of state change events you can analyze the situationbefore and after a historical event. A topology analysis and load flow and fault currentcalculations are performed, and the results are shown on the screen after each step. Loadmodels for the selected time are used in a network analysis if the load curves are in use.The simulation can be used for training purposes with real situations.

Step-by-step simulation contains the switch state changes of:• Disconnectors• Circuit breakers• MV fuses• Line sections.

The possible events for the devices are Open, Close and Uncertain. Other devices areskipped in simulation and LV switching actions are not included.

Alarm states of the devices are updated during the step-by-step simulation according tothe alarm information and saved into the event list.

Significant uncertainty occurs when using event log files cre-ated with Open++ Opera version 3.3, because the normalswitching state file must be used as a starting point in thehistorical simulation of those weeks (the normal switchingstate of medium voltage network is saved to the file byselecting File > Save as normal switching state). Some extrauncertainty occurs because the normal switching state file

This chapter does not apply to the DMS 600 (Base) license.The Extended Data Management license is required for thedefinition of additional load and border switch. The additionalload points and border switches have to be defined as separateload points in DMS 600 NE before they can be used in DMS600 WS.

Separate load points connected to any node in the medium voltage network can be usedin network calculations. The separate load points are taken into account during the networkcalculation by adding the active power of the measurement to the active power of thenode.

Separate load points connected to a disconnector, which is the ending point of a branchcan be used to model additional loads or a supply from a neighboring network that isnot included in the network database. If the state of the disconnector is 'closed' and thevalue of the measurement is negative (<0), the switch node supplies electricity to thenetwork. The branch becomes energized or a loop connection is formed if the electricitysupply to the switch is also coming from another direction. The discovery of loop con-nection is presented with a different color in the network window. If the supply is comingonly from the switch, the network supplied by this switch is colored with its own colorin the network window.

Topology management9.

Basic functions in topology management9.1.

General about topology management9.1.1.

Topology management in the DMS 600 WS network is an advanced and computerizedmethod which replaces the pins on a wall and/or mimics.

The state of switches defines the topology of the network. Topology management inDMS 600 WS is based on the integration of DMS 600 and MicroSCADA (for moreinformation about integration, see System Administration and Integration with SYS600). DMS 600 WS contains information on the switching state of the distribution net-work, that is, information on the states of all remotely and manually operated switches(including fuses) and line sections. In addition, you can use the manually updateablemeasurement data of border switches in topology management (for more informationabout border switches, see 8.19.2, Inserting the value for additional load and borderswitch).

The states of switches that are connected to MicroSCADA are updated using theMicroSCADA station and control pictures or control dialogs. If there is no connectionbetween DMS 600 and MicroSCADA, DMS 600 WS opens a dialog box in which youcan update the state of the switch. The status of line sections is always updated in DMS600 WS.

Switch state quality (status) received from SCADA9.1.2.

The DMS 600 interface to SCADA systems includes separate management of switchstate and its quality data. Separate symbols can be defined for uncertain switch states(open, uncertain or closed, uncertain). These symbols are used when a switch state isknown in SCADA database but switch quality is uncertain.

In an OPC interface, OPC quality QUALITY_UNCERTAIN and in a SCIL API interface,status values 1, 2 or 3 are interpreted as uncertain.

OPC quality QUALITY_BAD or SCIL API status 10 (not sampled) will cause the stateof a switch be shown as error.

The user can define whether uncertain state will cause the network coloring to useunknown color. Error state will always cause unknown coloring for the network.

104


Operation Manual

Monitoring network topology9.1.3.

Normally the medium voltage network is visible in network windows. Low voltagenetworks are always read separately to the memory. All functions focus on the activenetwork.

Every change in the state of the switches causes an update in the network topology (unlessthe topology is disabled in the general settings, for more information about general set-tings, see 7.4.1, Defining automatic function settings). The new network topology isimmediately shown in the user interface.

After a failure in the MicroSCADA system or in data transfer between DMS 600 WSand MicroSCADA, the real time switch status is read from MicroSCADA and the networktopology is updated accordingly.

The switch and measurement objects can have both an OPC code and a scadacode defined.If the OPC interface is closed in DMS 600 SA, the switch states and measurement valueshaving scadacode definition are still transferred through the SCIL API interface.

If the OPC interface is closed in DMS 600 WS, the switch states and measurement valuesthat are transferred through the SCIL API interface of DMS 600 SA are also transferredto DMS 600 WS.

Select View > Coloring > Topology by Feeders to display the adjacent feeders of thereal time topology with different colors. The feeder topology color settings are used innetwork diagrams, internal station diagrams, and in the root points of MicroSCADAstation and control pictures.

Select View > Coloring > Topology by Primary Transformers to display all lines fedfrom the same transformer in the real time topology with a common color.

Select Window > Notices and Events to open a window containing the last alarms ofDMS 600 WS.

Network topology coloring has special colors for the following (these also generate awarning to the list):• Looped connections (alarm also)• Unsupplied lines (alarm also)• Uncertain state• Grounded lines (temporary grounding or grounding switch).

The state of a switch is shown with the defined symbols of the network.

The definition of symbols and line colors is made by DMS 600 NE (for more informationabout definitions, see System Administration).

Changing switching states9.2.

General about switching states9.2.1.

• The switching states of all switches connected to MicroSCADA (real process objectsand virtual process objects) are updated using the MicroSCADA station and controlpictures or control dialogs.

• If there is no connection between DMS 600 and MicroSCADA for a switch, DMS600 WS opens a dialog box in which you can update the state of the switch.

• The state of line sections is always updated in DMS 600 WS.

DMS 600 WS has to be in State Monitoring Mode when updating the real time state ofthe switches. In Simulation Mode the changes are saved temporarily for the use of theworkstation.

In Automatic Fault Isolation and Restoration Mode, DMS600 WS performs the switching actions automatically.

Changing switching state of switches connected to MicroSCADA9.2.2.

Switches that are connected to the MicroSCADA process can be either remotely operatedreal process objects or manually operated virtual process objects. For more informationabout the integration of switches, see System Administration and Integration with SYS600.

The switching states of switches are updated with the dialog boxes of DMS 600 WSonly if there is a failure in the MicroSCADA system or in the data transfer between DMS600 WS and MicroSCADA (for more information, see 9.2.4, Changing switching stateof switches not connected to MicroSCADA). In that case, DMS 600 WS prompts aswitch to Simulation Mode. When data transfer capabilities are recovered, the real timeswitch status is read from MicroSCADA and the network topology is updated accordingly.

108


Operation Manual

To update the state of a switch connected to the MicroSCADA process:1. Select a switch or station with the mouse from the network window or network

diagram in DMS 600 WS. The MicroSCADA station and control picture opens.You can also select File > Change Switch State or View > Station diagram toselect the switch or station. When SYS 600 is used and switch configuration filesare available, you can open the control dialog for remote controlled switches directlyby selecting the switch from the network window, network or station diagram, orswitch device lists. You have control rights in the opened control dialog only if yourusername and password in the DMS 600 match with the user information in SYS600 and if you are authorized to control the selected switch.

2. Change the state of the switch. The topology of DMS 600 WS is automaticallyupdated in the network window (if not disabled in the general settings). For moreinformation about general settings, see 7.4.1, Defining automatic function settings).

Manual state update for switches connected to MicroSCADA9.2.3.

Disconnectors and circuit breakers normally receive status information from SCADA,but they can be changed into manual mode in DMS 600. In the manual mode, the statecan be updated like any switches that are not connected to SCADA.

Manual state can be used, for example, as a temporary solution to update and monitorthe state if communication to the station is down. Closed and temporarily open manuallyupdatable switches have different symbols.

To change a switch into manual mode right click the switch and select Manual stateupdate. This option is available only for switches that are connected to MicroSCADAand that are not in manual mode. The switch changes into manual mode, and a dialogopens, where you can update the state of the switch. If the quality of the switch wasuncertain or bad, it will be restored to normal.

To restore the switch back to the normal update mode, unselect Manual state updatefrom the state change dialog or right click the switch and select Remove manual update.

To restore all switches back into normal mode, select File > Remove Manual StateUpdate from the menu.

Changing switching state of switches not connected toMicroSCADA

Network and protection analysis11.

General about network and protection analysis11.1.


DMS 600 WS network analysis replaces traditional off-line calculations with on-linecalculations using the real-time state of the network.

With the network and protection analysis you can examine the electrical state of thenetwork and assure the technical functionality of the network in various circumstances.Network and protection analysis functions require the Network Analysis license.

Network analysis functions offer calculations for load flow and fault current (2- and 3-phase short-circuits and earth-faults) and the protection analysis of radial-operated andmeshed networks.

Generators and synchronous motors are taken into account as a source of short-circuitcurrent. The strong starting currents of asynchronous induction motors can be studiedin the load flow calculation. Additionally, distributed generators and capacitors are takeninto account in the load flow calculations. The calculations can also use measurementdata provided by MicroSCADA.

With the protection analysis function you can analyze overcurrent relays that have def-inite time-delays and inverse time types. The data source of all relay settings can bechanged between network models and active relay settings via MicroSCADA. In addition,the medium voltage fuses are taken into account during the protection analysis. The solidearthed networks and networks earthed via resistors are supported in the protectionanalysis.

The network analysis has different kind of aims in networkinformation system and distribution management system. Thenetwork analysis of the network information system is madein the peak load condition to be able to focus on theimprovements and additions of the network. With the networkanalysis of DMS 600 you can analyze the real-time networkstate and, thus, ensure the most effective and safe use of thenetwork. The load flow in DMS 600 is calculated using thegiven or estimated load information.

Operation Manual

Network analysis11.2.

Load modeling11.2.1.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license (with the Extended LoadModeling sublicense) is required for network analysis.

Load modeling uses Velander's factors or defined load models (load curves) to changeannual energy information for active and reactive power. The load model is selectednormally during the installation. The load model selection can be changed later on. Inthis case, the programs must be restarted and the network database updated.

The loads of MV/LV stations and customer nodes (if LV networks are included) and theeffect of capacitors are taken into account in load modeling during the network analysis.The loads inside the primary substations are not modeled. The load modeling uses single-line modeling that is capable to analyze balanced medium voltage networks (all mediumvoltage lines are 3-phased and the load on medium voltage side is nearly equally distrib-uted to all the three phases).

Manually updateable, separate load points connected to any node of the medium voltagenetwork can be used to model the separate load point, load of the border switch or backupfeeder from neighboring distribution network. The separate load points are taken intoaccount during the network calculation by adding the active power of the load point tothe active power of the node.

Manually updateable, separate load points connected to a disconnector that is the endingpoint of a branch, can be used to model an additional load or supply from a neighboringnetwork that is not included in the network database. If the state of this switch is 'open',the switch is handled normally in calculations. If the state is 'closed' and the value of themeasurement is negative (<0), the switch node supplies the electricity to the network.The branch either becomes energized or a loop connection is formed, if the electricitysupply to the switch is also coming from another direction. The discovery of the loopconnection is presented with a color code in the network window. If the supply is comingonly from the switch, the network supplied with this switch is colored with its own colorin the network window. This network is not calculated during the load flow calculation.If the positive active power measurement is inserted into the switch, the amount of activepower is added to the power of the node as in the case of separate load points.

Operation Manual

Load forecasting and load estimation11.2.2.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license (with the Extended LoadModeling sublicense) is required for network analysis.

Load forecasting is the calculation of the load forecast for MV/LV stations and linesections for the next 0 to 168 hours. The forecast is based on the load data of MV/LVstations or LV/MV network customers depending on the selected load modeling method.

Load estimation is the correction of loads given to MV/LV stations so that the total cal-culated loads of the feeders approximate to the current measurement of the feeder. Theelectrical state of the network can be calculated as accurately as possible. When there isno load estimation available, the forecasted loads are created directly from the givenMV/LV station load data.

DMS 600 SA automatically calculates a load estimation and a load forecast for theMV/LV stations once an hour. The calculations use the latest MicroSCADA measurementdata (for more information about MicroSCADA measurements, see 11.2.4, Using ofMicroSCADA measurement data in network analysis ). After the load forecast databaseis updated, it is loaded to be used in DMS 600 WS workstations.

DMS 600 SA starts a separate estimation process by default 5 minutes past each hour.It is recommended to update the real time estimated loads just after new hourly valuesare taken into use from the load curves. The time can be changed by adding a specialparameter to the settings file Common.prm. To change the time, add the following rowinto the [Common_Settings] section:

EstimationStartMinute=xx

xx is the start time in minutes after the hour.

In addition, DMS 600 SA reads measurement values two minutes before the estimationminute to ensure that recent estimation values are available. In normal case measurementsvalues are updated continually to the DMS 600 database just after the changes.

Showing load curve for MV/LV stations and line sections11.2.3.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license (with the Extended LoadModeling sublicense) is required for a network analysis.

124


Operation Manual

DMS 600 SA maintains load forecasts for MV/LV stations as a background process.Load estimation is used to correct the given loads of MV/LV stations so that the totalcalculated load of the feeders approximates to the current measurement of the feeder(for more information about load estimation, see 11.2.2, Load forecasting and loadestimation). The load forecast of MV/LV stations is updated automatically in the databaseonce in an hour.

To show the load forecast graphically:• Open the shortcut menu by right-clicking a node or a line section. Select Load

Curve from the shortcut menu.• Click Load Curve in the node information dialog box.

The Load Curve dialog box contains the forecasted load of the appropriate line sectionor, if a MV/LV station is selected, the end node's forecasted load for the next week.• The green line describes the original real power load according to the load data of

the MV/LV station.• The red line describes the forecasted load generated in the load estimation.

The window also contains the forecasted maximum and minimum powers and theinterval of them from the present time. In case of a line section, the forecast calculationis started to illustrate the forecast in the window.

With the load curve information for a selected line section you can find a convenienttime period, for example, for a maintenance outage. To show the distance from thepresent time and the forecasted load in that time, click the load curve.

Using of MicroSCADA measurement data in network analysis11.2.4.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license is required for network analysis.

The configuration of the connection between MicroSCADA measurements and the DMS600 network database is made in DMS 600 NE (for more information about configura-tions, see System Administration).

If the measurement data is connected to the nodes of the network, the measurement dataserves as input data for the network analysis of DMS 600 WS in the following way:• To make the load data of the feeder and the MV/LV stations more accurate, use the

current measurement connected to the feeder's node or to the node that limits theMV/LV station and the feeder (node type feeder) during the load estimation (formore information about using the load estimation, see 11.2.2, Load forecasting andload estimation). The current measurements that are connected to a node whichbelongs to a feeding HV/MV substation cannot be used in the load estimation.

• A current measurement, an active power (P) measurement, or a reactive power (Q)measurement connected to a motor node: The change in motor measurement data

125


Operation Manual

affects to the load flow calculation results in the radial calculation of WS. If onlycurrent measurement is available it is used so that the voltage in the measurementpoint is used to estimate the total power (S). In Simulation Mode the user can switchthe P and Q values. When returning to State Monitoring Mode the real measurementvalues are restored.

• A current measurement, an active power (P) measurement, or a reactive power (Q)measurement connected to a generator node that is connected to a Generator BlockTransformer: The change in generator measurement data affects to the meshed net-work load flow calculation results in loop calculation of WS. If only current meas-urement is available it is used so that the voltage in the measurement point is usedto estimate the total power (S). In Simulation Mode the user can switch the P andQ values. When returning to State Monitoring Mode the real measurement valuesare restored.

• Use the primary substation voltage measurement as a supplying voltage for feedersin the load flow calculations. When available, always use the measured voltageinstead of the primary transformer's nominal voltage from default busbar voltagesettings (for more information about default settings, see 7.6.1, General about networkand protection analysis settings). The voltage measurement must be connected to anode belonging to the HV/MV substation which is used in the calculation. A voltagemeasurement connected to a feeder node cannot be used in the calculation.

• Separate load points connected to any node of the medium voltage network can beused in network calculations. The separate load points are taken into account duringnetwork calculation by adding the active power of the measurement to the activepower of the node.

• Separate load points connected to a disconnector that is the ending point of a branchcan be used to model additional loads or a supply from a neighboring network thatis not included in the network database.

For more information about inserting the value for manually updateable load point, see8.19.2, Inserting the value for additional load and border switch.

Using starting motors in network analysis11.2.5.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license is required for a network ana-lysis.

The use of starting motor data means that the real and reactive powers of inductionmotors are replaced with the starting current and power factor during a network analysis.

You can define only induction motors to be used as a startingstate in the network analysis.

126


Operation Manual

To define induction motors that are in the starting state:1. Select Analyze > Starting Motors. The dialog opens and shows all induction motors.2. Select one or more motors from the list.

You can leave the dialog open to easily change the selected starting induction motors.

Performing network analysis11.2.6.


When the start up process is completed, DMS 600 WS is in State Monitoring Mode (ifthe fault location is not started). A medium voltage network topology is displayed in themain network window.

The network analysis is automatically performed during the start up process. The networkand the results of the network analysis in the network windows are based on data fromthe network database, temporary network and real time switching state. The feedingvoltage (busbar voltage) is received from a primary substation voltage measurement orfrom primary transformer settings and the loads are received from the given loadinformation and from separate load points. The current measurement is used during theload estimation to make the load data of the feeder and MV/LV stations more accurate.An auxiliary window contains the voltage drops in different parts of this existing mediumvoltage network. The default contents of the windows can be changed during projecting.

The change in network and/or switching state data automatically recalculates the networkand updates network topology on screen (if not disabled in the general settings. For moreinformation about general settings, see 7.4.1, Defining automatic function settings). Theanalysis is executed for radial feeders. After this the meshed network load flow andmaximum short-circuit current calculation for the whole medium voltage network areperformed automatically, if this is configured in the settings and the time interval fromthe last calculation has elapsed (for more information about general settings, see7.4.1, Defining automatic function settings).

If a current measurement, an active power (P) measurement, or a reactive power (Q)measurement are connected to a motor node, the change in the motor measurement dataaffects the load flow calculation results in the radial calculation of WS. If only the currentmeasurement is available, it is used so that the voltage in measurement point is used toestimate the total power (S).

The meshed network load flow is calculated for the total network even if it consists ofseveral isolated networks. An isolated island is a part of network fed by one or severalprimary feeding transformers but isolated from other network. Several islands can beconnected to each other but isolated by open switches. If automatically meshed network

127


Operation Manual

analysis is used, the maximum short-circuit currents are calculated for all the isolatedislands after a change in switch status (for more information about general settings, see7.4.1, Defining automatic function settings).

If a current measurement, an active power (P) measurement, or a reactive power (Q)measurement are connected to a generator node that is connected to a Generator BlockTransformer, the change in generator measurement data affects the meshed network loadflow calculation results of the loop calculation.

When the automatic updating of radial feeders or meshed networks is not in use, youcan select Analyze > Network & Protection and Analyze > Meshed Network Analysisto execute a network analysis.

Feeder power and loss reports11.2.8.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license is required for feeder load flowreports .

The estimation program maintains load flow calculation results in the database of eachMV feeder of each hour of the current and previous month. Each hour that the loadestimation is run, the program also updates the feeder results for all feeders. This includesall feeders even if no measurement value for the load estimation has been defined forthe feeder. The data of previous months will be removed at the beginning of a new month.

The load flow calculation uses estimated loads for MV/LV substations when measure-ments have been defined. If needed, the functionality can be removed by adding a linefor key LossReporter=0 under section [Common_settings] in Common.prm file.

The results include active power (P), reactive power (Q), active power losses, reactivepower losses, energy, energy loss and biggest voltage drop for each feeder and hour.The MS Access based reporting tool (FeederReport.mdb) provides results of peak loadhours. The data can naturally be fetched from relational database server using linkedtables.

The short-circuit capacity is the percentage ratio of a 3-phase short-circuit current overthe calculated maximum permissible short-circuit current for the conductor. It is calculatedusing the equivalent duration of the short-circuit and the short-circuit capacity (1 s) ofthe conductor. If the relative value is less than 100%, the conductor can stand the short-circuit. If the relay is not tripping, dashed lines are appearing here.

Short-circuit detection means the percentage ratio between 2-phase short-circuit currentand the relay setting. If the value is higher than 100%, the relay will trip.

Operation Manual

Fault management12.

General about fault management12.1.

This chapter does not apply to the DMS 600 (Base) license.The Fault Location license is required for fault management.

The main functions of MV fault management are:1. Fault location2. Sending of GSM messages to important customers3. Fault isolation and restoration planning4. Execution of the planned switching sequences5. Fault reporting (for more information about fault reporting, see 14.4.1, General

about reporting fault and maintenance outages)6. Fault archiving (for more information about fault archiving, see 14.6, Archiving

outage data)

Several medium voltage faults can be managed at the same time with fault management.Automatic fault isolation and restoration handles one fault at a time.

DMS 600 WS contains the manual management of low voltage network faults (for moreinformation about LV fault management, see 12.11, Management of LV outage).

General progress of the MV fault management12.2.


The progression of fault clearance depends on the use of the automatic fault isolationand restoration function and the type of fault.

A new fault causes automatic zooming into the area of the faulted feeder. Other simul-taneous faults are not zoomed, but the faults are processed in the background (for moreinformation about automatic zooming, see 7.4.1, Defining automatic function settings).

Fault management starts with fault location (for more information about fault location,see 12.5.1, General about fault location). After fault location, a GSM message about theoutage can be sent to important customers automatically or manually. The default valuesused in the message are based on the active fault and possible reconfiguration. The defaultGSM message is sent to customers without supply.

143


Operation Manual

If DMS 600 WS is in the Automatic Fault Isolation and Restoration Mode and the faultis definitely located during the fault location function, the isolation and restorationplanning is started automatically. If the automatic function is not in use or the fault cannotbe located definitely, the isolation and restoration planning can be started manually afterthe location of the fault (for more information about setting the fault location manually,see 12.7.1, Selection of active fault).

After the fault isolation and restoration planning, DMS 600 WS can execute the plannedswitching sequence. The execution is automatic or manual, depending on the functionsettings (for more information about the execution of fault isolation and restoration, see12.6.2.1, General about automatic fault isolation and restoration and 12.6.3, Generalabout manual fault isolation and restoration). After the fault is repaired, the fault data issaved to the fault archive (for more information about archiving, see 14.4.1, Generalabout reporting fault and maintenance outages).

as default.• To view the default areas by the username, click Restore default Areas.• To enable fault filtering according to selected areas, click OK.

Fault location12.5.

General about fault location12.5.1.


The fault location function deals with permanent feeder faults occurring in radial operated,neutral isolated, compensated or neutral earthed distribution networks. In meshed net-works, the fault location works only if the faulted feeder or an opened circuit breaker isfeeding a radial branch. Busbar faults (no feeder for an opened circuit breaker) are locatedin the same way as radial feeder faults.

If there are problems with the MicroSCADA connection, the fault location simulationcan also be used for real faults as described in 12.8.6, Locating real faults in MicroSCADAdisconnection.

Permanent faults in a distribution network are detected by relays connected to Micro-SCADA. When a permanent fault has occurred, the required fault data collected byMicroSCADA is automatically sent to DMS 600 WS. The states of the remotely readablefault detectors are obtained from MicroSCADA.

After that, DMS 600 WS automatically starts the fault location function and shows thepresent topology of the network. DMS 600 WS analyzes the fault data and inferencesthe most likely fault locations. All line sections that are possible fault locations basedon the fault distance calculation are shown on the screen using the alarm color.

145


Operation Manual

Possible fault locations along the feeder in which a fault has occurred are determined onthe basis of the following information:• Fault distance calculation (based on sequence representation, if necessary).• Fault detector data.• Type of line sections (underground cable/overhead line).• Overload conditions for distribution transformers and cables.

The fault location of short-circuits and earth-faults based on the transferred fault detectordata can be used in any kinds of networks. However, fault location based only on faultdetectors can locate a fault to a feeder zone determined by fault detectors not accuratelyto a point along feeder.

The fault distance calculation requires fault current or impedance registration, for example,for relays and data transfer from process via MicroSCADA. The fault data needed forthe fault location function of DMS 600 WS can be automatically transferred fromMicroSCADA. Only fault detector data that is read on-site has to be updated manuallyin DMS 600 WS (for more information about fault detectors read on-site, see12.5.3, Management of on-site readable fault detector state).

If data is missing and the fault location cannot be calculated, the faulted feeder is stilldisplayed on the screen with zooming, and the Fault Management dialog indicates anew fault.

For more information about fault location parameters, see 12.5.1, General about faultlocation and System Overview.

Fault distance calculation12.5.2.

Fault distance calculations can use the following methods:1. Magnitude of short circuit current (A)2. Impedance (reactance) from the relay to the fault location3. Distance (meters) from the relay to the fault location

The method using current magnitude can calculate the fault distance in case of 2- or 3-phase short-circuits and 1-phase or 2-phase to earth short-circuits in earthed networks.However, earth short circuits cannot be located if the substation is fed from a loop becausethe feeding impedance components cannot be determined. In neutral isolated or com-pensated networks, 1-phase to earth short-circuits cannot be located using the currentmagnitude method.

The method using reactance from the relay to the fault location can be used in any kindsof networks. The distance to fault can also be calculated in case of 1-phase to earth faultsin neutral isolated networks. In these cases the given reactance is the sum of positiveand zero sequence reactances. Normally the accuracy of available reactance measurementis lower, especially in compensated networks.

146


Operation Manual

The method using distance from the relay to the fault location can be used in any kindof a network. The fault location is calculated directly from the lengths of the sections inthe network model.

Management of on-site readable fault detector state12.5.3.


The states of the remote readable fault detectors are obtained from MicroSCADA butthe on-site readable detectors are managed by the user interface of DMS 600 WS.

If there are any faults under fault management in DMS 600WS, a change of the fault detector state also causes a new faultlocation function for the active fault to be run again using thenew fault detector information.

To change the operational state of detectors:1. Click a fault detector in the network window or on the diagram to open the Fault

detector data form.2. Change the operational state of an on-site readable detector by selecting Operated

or Non-operated. The network window is updated and a message sent to all instancesof DMS 600 WS to read the new fault detector state from the DMS 600 database.The fault location function for the active fault is run again using the new fault detectorinformation.

The operational time of an on-site readable detector is managed by DMS 600 WS, sothat the operational time is always the present time relating to the selection of a state.

If DMS 600 WS is in Simulation Mode (for example, while studying an old repairedfault), you are asked if you want to store the update permanently in the real time DMS600 database, too. The selection of a state always affects the network model and the faultfile under simulation.

Progress of the fault location12.5.4.


MicroSCADA detects a fault and switches to DMS 600 SA and DMS 600 WS. WhenDMS 600 WS receives information of a new fault, it runs the fault location function. For

147


Operation Manual

more information about settings, see 7.4.1, Defining automatic function settings. Whenthe fault location function is running, the user interface of DMS 600 WS contains twonetwork windows. The main network window is automatically zoomed to the feeder inwhich a fault has occurred. The feeders are shown according to the switching state (thefeeder that has been faulted is shown with an unsupplied color) and possible faulted linesections are shown with an alarm color in the main network window. Other feeders areshown according to the switching state of the feeders. The bottom-right corner includesthe resizable Fault Management dialog box which is the basic dialog box for gettinginformation on faults.

If the fault location function of DMS 600 WS cannot locate the fault definitely ("Faultnot located" text is visible in the dialog), the management of the fault is continued withthe functions of the Fault Management dialog (for more information about fault man-agement, see 12.7.1, Selection of active fault).

If DMS 600 WS is in the Automatic Fault Isolation and Restoration Mode, the FaultManagement dialog is disabled and the Automatic Operation Mode Running dialogis active. For more information about automatic fault isolation and restoration, see12.6.1, General about fault isolation.

Fault isolation and restoration12.6.

General about fault isolation12.6.1.

This chapter does not apply to the DMS 600 (Base) license.The Fault Location license with the Restoration Support sub-license is required for fault management.

The fault isolation and restoration planning necessitate the definition of fault locations(for more information about fault location, see 12.5.1, General about fault location).Fault location can be based on the automatic fault location function or the faulted zonecan be defined manually. The definition of the faulted zone for the isolation and restorationplanning is done automatically, if the probability of the fault in some remotely controlledzone is larger than the lower limit of the faulted zone and the probability of a fault inother zones is smaller than the upper limit of the other zones (for more information aboutfaulted zone parameters, see 7.8.2.3, Faulted zone location settings).

Fault isolation and restoration planning generates the switching sequence that takes intoaccount the technical constraints of the network and the protection demands. Voltagedrop, short-circuit detection, earth-fault detection, short-circuit capacity and load levelfor each line section included in the planning are checked (for more information aboutswitching planning parameters, see 7.8.3, Switching planning settings).

Figure 12.6.2.2-1 The flow of the fault management in the Automatic Fault Isolation andRestoration Mode

After Automatic Fault Isolation and Restoration Mode detects a new fault:1. DMS 600 WS receives information of a new fault, waits for a delay (defined by

Fault Location Start Delay (s) in DMS 600 NE) and runs the fault location functionautomatically.

2. If DMS 600 WS cannot locate the fault definitely, the management of the fault mustbe continued manually. For more information about manual fault management, see12.6.3, General about manual fault isolation and restoration. If DMS 600 WS canlocate the fault definitely to a remotely controlled zone (or a feeder without remotelyoperated switches), DMS 600 WS automatically starts the fault isolation and restor-ation planning. The result of the planning is the switching sequence.

3. The generated switching sequence is automatically executed. After the startup ofthe automatic sequence, DMS 600 WS presents the status the Automatic sequencerunning. If the whole switching sequence was successful, DMS 600 WS waits forthe delay (defined by Switching State Update Delay (s) in DMS 600 NE) andchecks that the current switching state is similar to the switching sequence plan.Only if no errors occur during the sequence, and the two switching states are similar,DMS 600 WS continues normally and may start another restoration sequence if anew fault appears, otherwise the status will be changed to "Automatic fault isolation

Fault location simulation12.8.

General about fault location simulation12.8.1.


Fault location simulation can be used to:• Locate real faults with changed fault information or fault location parameters.• Insert new real fault data and locate faults (especially if there are problems with the

MicroSCADA connection).• Demonstrate a fault for simulation purposes (for example, a fault cleared by the

protection relay's autoreclosing function can be studied afterward using the manuallyread values measured from the relay).

Operation Manual

To create a new fault for areas fed by a disconnector or an MV fuse, select Create Faultfrom the short cut menu of the switching device.

Create Fault command will appear in the short cut menu if the feeder, in which theswitching device is located, is not looped or meshed, and at least one side of theswitching component is powered.

Locating real fault with changed data12.8.3.


After MicroSCADA detects a new fault, the fault location function runs using the realfault data that is automatically transferred from MicroSCADA and the fault locationparameters defined by the administrator. To simulate a real fault, you can select it fromthe list of all faults.

Changing fault information12.8.4.


To change real fault data transferred from MicroSCADA:1. Click Fault information in the Fault Management dialog box. The Fault

information dialog box opens showing the detailed information on the active fault.For more information about fault data, see 12.7.3.1, Base data of fault.

2. Change the fault information. Here are some notes for the changing:Earth short-circuit faults can be selected only if the network is earthed.•

• In the case of a permanent fault and final tripping, which normally starts thefault location function, the last measured value of the short-circuit current isused as a default in the fault distance calculation. Generally, an autoreclosinghas preceded the final tripping. Therefore, the register also includes the measuredvalues relating to the autoreclosing operation. For simulating the fault locationwith the fault current of the first circuit breaker opening (that is, when the faultreally occurs), the correct value is selected from the buffer dialog box andwritten in the fault current field.

• Normally fault location uses the feeding network's short-circuit impedancevalues that are associated with the main transformers. To use alternativeswitching states in the feeding network, you need different feeding networkimpedance values. Alternative feeding network impedance values can be usedif they are defined (for more information about the definition of alternative

165


Operation Manual

network impedance values, see System Administration). If the alternativeimpedance values are defined, the Fault information dialog contains theAlternatives box which presents the descriptions of the alternative feedingnetwork for the selected main substation and circuit breaker. Select the desiredalternative situation and the corresponding resistance and reactance values. Touse the values associated with the main transformers, select Default.

• If resistance or reactance values are changed manually during fault location,they can be saved to the fault file when the defined fault state is "repaired" (willbe prompted). These values cannot be saved at the fault simulation.

Operation Manual

Switching planning13.

General about switching planning13.1.

This chapter does not apply to the DMS 600 (Base) license.The Network Analysis license with the Operation Planningsublicense is required for switching planning.

Switching planning functions require the Network Analysis license. The isolation andrestoration planning made during the fault management also requires the Fault Locationlicense.

The main functions of switching planning are:• Isolation and restoration planning can be used in experimental switching planning

(for more information about fault isolation and restoration planning, see12.6.1, General about fault isolation).

• Maintenance outage planning is used in the planning of switching actions that areneeded to disconnect line sections for outages and to restore supply after an outagewith as little disturbance to the customers as possible.

• Contingency analysis by stepping through predefined sequences. The sequencespresent major outage situations in the network. Measurement value adjustments ofload and generation points (motor and generator power changes) can be includedinto the sequences. Also Analyze Contingency commands can be used in thesequences, and if any violations are found in the network analyses, a report is gen-erated. The report can be set to contain both topology and calculation violations, oronly violations during the network calculation.

• Reconfiguration planning helps to find an optimal switching state with minimallosses in the existing load situation.

Automatic planning functions generate the switching sequence which informs about thetechnical constraints of the network and the protection demands. Voltage drop, short-circuit detection, earth-fault detection, short-circuit capacity and load level are checkedfor each line section included in the planning (for more information about switchingplanning parameters, see 7.8.3, Switching planning settings). In addition to automaticswitching planning, you can also create a switching sequence manually in DMS 600WS.

The switching sequence contains the opening and closing of switch devices, simulatedpower values to motors and generators if contingency analysis was used, and other actionsneeded during an outage (for more information about the data content of the switchingsequence, see 13.10.1, Plan data). You can modify, simulate and execute switchingsequences that are created manually or with the maintenance outage planning function.

Outage data management14.

General about outage data management14.1.

This chapter does not apply to the DMS 600 (Base) license.The Outage Reporting and the Statistics licenses are requiredfor outage data management.

The outage data management requires the Outage Reporting and Statistics license. TheFault Location, Low Voltage Networks and Operations Planning licenses are needed forthe full operation of the function.

The main functions in outage data management are:• LV network outage reporting• MV fault reporting• MV maintenance outage reporting• Reclosing reporting• Retrieval of customer and MV/LV station specific outage data• Archiving of outage reports

General about outage data14.2.

This chapter does not apply to the DMS 600 (Base) license.The Fault Location license is required for outage information.

The duration of a fault as well as the number of unsupplied customers for each outageis available for users without the need to use the Fault Management dialog, or openingthe switching plan. Information about the active faults and maintenance outages iscombined with the network topology.

Reporting fault and maintenance outages14.4.

General about reporting fault and maintenance outages14.4.1.

This chapter does not apply to the DMS 600 (Base) license.The Outage Reporting and Statistics license is required foroutage data management.

Outage reporting is used for the reporting of basic outage data and actions during a faultclearance and maintenance outage.

When a fault report is opened for the first time and if Save switchings to fault file isnot selected, a dialog box for confirming fault starting and ending times is shown.Switching data is read from the switching log, and stored to the fault file. For moreinformation, see 12.1, General about fault management.

188


Operation Manual

DMS 600 WS generates an outage report template. Most of the template's fields are filledin advance on the basis of the executed sequence. You can define the exact MV faultlocation by pointing the location in the network window before reporting. The systemcalculates key values of the MV outage on the basis of outage data (for more informationabout reporting settings, see 7.8.4, Reporting settings). The operator completes the reportand saves the data into archives for later use.

The fault reporting function is used after the fault has been repaired, the supply is restoredand the fault is set to repair. The maintenance outage reporting function is used after theoutage has been repaired and supply is restored.

Fault and maintenance outage reports can also be created by defining an interruptionarea. In this case outage data is not needed.

Outage reporting is performed in the control center. Other workstations can only scanthe outage report data. Only a user who has rights to perform the fault management andis responsible for the appropriate fault or maintenance outage can update the fault reportdata of the outage.

Reporting of LV network outages14.4.2.


The customer normally notifies about a low voltage network fault. Information about afault can be saved to DMS 600 WS during the fault. LV outage maintenance data canalso be saved using LV network outage management in the same way as in fault cases.For more information about LV outage data management see 12.11, Management of LVoutage. Data about saved LV outages can be used to create a LV network outage reportwhich can be archived in an archive.

To create a LV outage report:1. Select Fault > LV Network Outage Report to open a list of all saved LV network

outage data.2. Select the desired outage and click OK to open the outage data. The Outage dialog

Exporting outage data14.8.

This chapter does not apply to the DMS 600 (Base) license.The Outage Reporting and Statistics license and the AdvancedReporting Management sublicense are required for exportingoutage data.

DMS 600 WS enables the exporting of defined outage data to a file. This outage datafile can then be imported, for example, to a customer's information system.

Exported outage data is collected from reported outages in DMS 600 database using thequery function. The query is formed using the outage type, starting and ending dates andoutage duration. The export file contains outage areas and data about them. Every outagearea is saved to the export file only once.

To export outage data into the export file:1. Select Fault > Outage data export. The New outages to be exported to a transfer

file dialog opens.2. Select report type or types.3. Define limits for starting and ending dates. Insert date in the form dd.mm.yy (for

example, 01.01.04).4. Define the limits for the duration of the outage. Insert the duration times in the form

hh:mm:ss (for example, 01:00:00).5. Select the archives that are included in the query.6. Click Execute. Outage areas that meet the query limits and are not yet exported to

the file, will be shown on the dialog.7. Click Export to file.

Operation Manual

Database analysis15.

General about database analysis15.1.

The database analysis produces summaries and data collections from the network database.

The analysis is based on queries. DMS 600 software contains a default group of queries.An experienced user can create queries of his/her own using the capabilities of the fullversion of MS Access (for more information about creating queries, see SystemAdministration). Simple queries can also be created using the graphical query creationfeature in DMS 600.

A query can cover the entire network data or a selected object group. The query filterscan contain one or more constraints (for example, manufacturing year before 1970 andthe last maintenance made before year 1995) which are then used to filter the data fromthe database.

The results of queries can be viewed in table format in MS Access. The queries containingcoordinate or node code data can be viewed in graphical form in DMS 600.

Any saved queries can be added to DMS 600 menu commands. Reports from the networkdatabase can also be run using DMS 600 WS menu commands.

A full or runtime version of MS Access is needed, dependingon the covered tasks.

Queries in DMS 600 software15.2.

Query results in DMS 600 software15.2.1.

Graphical queries saved in MS Access can be executed in DMS 600. Simple graphicalqueries can also be created using the functions of DMS 600.

Only graphical queries are shown in DMS 600.

Any saved MS Access queries can be added to the DMS 600 software menu View >Access Queries as a command (for more information about adding queries to menu, see15.4, Adding query command to menu ). Select View > Access Queries > "QueryName" to open MS Access and show the query results in table format (for moreinformation about functions in MS Access, see System Administration).

Operation Manual

Performing ready graphical query15.2.2.

To perform a graphical query:1. Select View > Database Queries > Select Query to Execute to open a dialog box

for selecting a query. The list contains all graphical queries of the database (queriescontaining coordinate fields X and Y or node code field NODE CODE). If the querycan be restricted graphically, focus the query by selecting the objects before perform-ing the query (for more information about using graphical restriction on the query,see 15.2.3, Graphical restriction of the query focus ).

2. Select the desired query.3. Insert the query parameters if needed.

Results of the query are displayed graphically in the main network window and numer-ically in the information window.(For more information about symbols, see SystemAdministration).

Select View > Database Queries > Query Info to open an information window thatshows the name of the query and the object results.

Select View > Database Queries > Clear Results in Network Window to remove theresults from the screen.

Graphical restriction of the query focus15.2.3.

If the graphical restriction has been taken into account during the query design IfSELECTED_NODES table is included to the query, it is possible to restrict a query tothe graphically selected nodes.

Before performing the query, restrict the query focus graphically in the following way:1. Select View > Database Queries > Select Nodes in Network Window to start the

restriction of the query.2. Select the object type for restriction using the list (contains also the free database

objects) or check the All node types check box to select all regular node types tobe included in the query (not the free database objects).

3. Define the area of the restricted query by clicking one corner of the area, draggingthe cursor and releasing it on the opposite corner. The number of selected nodes andthe nodes' codes and names are shown in the Selected Nodes dialog box

4. Click Remove to remove the selected node from the list. Use Browse to open a freedata form of the first selected node.

5. Click OK to save the contents of the dialog box into the table SELECTED_NODEStable in the database.

Operation Manual

Creating simple graphical query in DMS 600 software15.2.4.

This chapter does not apply to the DMS 600 (Base) license.The Extended Data Management license is required for creat-ing queries.

You can create simple graphical queries and present the results of several graphicalqueries simultaneously with the DMS 600 functions.

You need the full version of MS Access to create graphicalqueries in DMS 600.

To create a query:1. Select View > Graphical Database Queries to open the dialog box for query

definitions. The dialog box contains five separate query fields. Each field containsthe definition of one query.

2. Select the base for each query from the list that contains all graphical tables andqueries of the database (tables and queries containing the coordinate fields X andY or the node code field NODE CODE).

3. Define query constraints for each query. Each query can have two constraints. Selectthe field for a constraint from the list that contains all the fields of the selected tableor query. Insert an individual value or a normal SQL operator (<,<=,>,>=,<>,*)together with the value for the selected field. The acceptable values for a field canbe figured out by opening the table or query in MS Access. If both edit boxes areleft empty, all records of the table or query are included in the results. If only oneconstraint is needed, the edit box of the other part is left empty.

4. Define the combination of the two query constraints by selecting and or an operatoroption.

5. Select the Execute check box to take the query into account during the execution.6. Define a symbol for the results of each query. Click Color to open the standard

color definition dialog box. Define the size of the symbol by selecting it from a list.7. Perform the selected queries by clicking Execute. The results are shown in the main

network window. The network window can be zoomed and panned normally.

The number of resulting objects in the network database and in the existing networkwindow is shown in the dialog. The data is refreshed after every change in the zoomingof network window.

To clear the values of all fields and remove the query results from the network window,click Empty All.

To save the queries and definitions of the dialog box into a file, click Save and definethe file in the standard file-saving dialog box.
