SICAM PASSubstation Automation System

SICAM PAS (Power Automation System)meets all the demands made of a distri-buted substation control system – bothnow and in the future. Amongst manyother standardized communication proto-cols SICAM PAS supports the new stand-ard IEC 61850 in the substation for com-municating with the bay devices. SICAMPAS is an open system and besides provid-ing standardized data transfer processes, itfeatures user interfaces for the integrationof system-specific tasks and offers multipleautomation possibilities.

SICAM PAS can thus be integrated withease in existing systems and can be used forsystem integration too. With modern diag-nostics, it optimally supports commission-ing and maintenance.

SICAM PAS is clearly structured and reli-able, thanks to its open, fully documentedand tested system.

Description/Application

System overview, application andfunctionality of SICAM PAS

• SICAM PAS is an energy automationsolution; its system architecture makes itscalable.

• SICAM PAS is suitable for operating asubstation not only from one single sta-tion computer (station unit), but also incombination with other SICAM PAS sys-tems or station control units. Communi-cation in this network is based on apowerful Ethernet LAN.

• SICAM PAS for safe substation automa-tion based on robust hardware compo-nents (non-rotating components) andan embedded operating system.

• With its features and its modular expand-ability, SICAM PAS covers a broad rangeof applications and supports distributedsystem configurations. A distributedSICAM PAS system operates simulta-neously on several computers.

• SICAM PAS can use existing hardwarecomponents and communication stan-dards as well as their connections.

• SICAM PAS controls and registers theprocess data for all devices of a substation,within the scope of the data transfer pro-tocols supported.

• SICAM PAS is a communication gateway.This is why only one single data connec-tion to a higher-level system control cen-ter is required.

• SICAM PAS enables integration of a fullygraphical process visualization systemdirectly in the substation.

• SICAM PAS simplifies installation andparameterization of new devices, thanksto its intuitive user interface.

• SICAM PAS is notable for its onlineparameter setting features, particularlywhen the system has to be expanded.There are no generation times, and thereis no need for loading into a target system(unless configuration is performed on aseparate engineering PC).

• SICAM PAS features integrated testing anddiagnostic functions.

• Its user-friendliness, its operator controllogic, its orientation to the Windowsworld and its open structure ideally suitusers’ requirements.

Fig. 14/2Typical SICAM PAS configurationIEDs are connected to the station unit with IEC 61850 and various other protocols(IEC 60870-5-103, IEC 60870-5-101, PROFIBUS FMS and PROFIBUS DP). The station unit communicatewith the higher-level system control center by means of IEC 60870-5-104.

SICAM PAS works on PC-compatiblehardware with the Microsoft Windows2000, Windows XP Professional and Win-dows XP Embedded and Windows 2003Server operating systems. The advantagesof this platform are low hardware andsoftware costs, ease of operation,scalability, flexibility and constantlyavailable support.

With the powerful real-time data distri-bution system, applications can be allo-cated among several computers, thusboosting performance, connectivity andavailability.

A system stores and organizes the data-base (e.g. configuration data, administra-tive status data, etc.).

The device master function for commu-nication with Intelligent ElectronicDevices (IEDs) supports a large numberof well-established protocols.

The SICAM PAS data normalizationfunction allows such conversions as mea-surement filtering, threshold calculationand linear characteristics.

SICAM PAS CC is used for process visu-alization. Specifically designed for energyautomation, it assists in optimization ofoperations management. It provides aquick introduction to the subject matterand a clearly arranged display of the sys-tem’s operating states.

SICAM PAS CC is based on SIMATICWinCC, well-known in industrial auto-mation worldwide.

To facilitate incident analysis, the faultrecordings from protection units areretrieved and archived automaticallyduring operation. This is supported bythe IEC 61850 and PROFIBUS FMS(SIPROTEC 4) protocols, or theIEC 60870-5-103 protection units proto-col. SICAM Recpro is used for archivingand navigation in the fault recording ar-chive. Fault recordings are visualizedwith Comtrade View (included withSICAM Recpro). Alternatively, SIGRA 4can also be used.

Communication

Device interfaces andcommunication protocols

In a substation that you configure and op-erate with SICAM PAS, you can use vari-ous types of protection units, IEDs, baycontrol units, measured-value recordersand telecontrol units from a wide range ofmanufacturers.

SICAM PAS offers a large number of com-mercially available communication proto-cols for recording data from various de-vices and through differing communicationchannels. Subsequent expansion is easy.

Available protocols

These communication protocols and devicedrivers can be obtained as optional addi-tions to the standard scope of SICAM PAS.

IEC 61850

IEC 61850 is the communication standardfor interconnecting the devices at the bayand station control levels on the basis ofEthernet. IEC 61850 supports the directexchange of data between IEDs, thus en-abling switching interlocks across bays in-dependently of the station control unit, forexample.

PROFIBUS FMS

Most SIPROTEC 4 bay controllers andprotection units can be connected to theSICAM PAS station unit with PROFIBUSFMS. Many of the functional aspects stan-dardized in IEC 61850 have been antici-pated in this communication platform.

IEC 60870-5-103

Protection units, IEDs, bay control units,measured- value recorders and trans-former controllers from many manufac-turers support the IEC 60870-5-103protocol and can therefore be connecteddirectly to SICAM PAS.

IEC 60870-5-101 (master)

The IEC 60870-5-101 protocol is generallyused to connect telecontrol units.

The ‘balanced’ and ‘unbalanced’ trafficmodes are supported.

Automatic dialing is also supported for theconnection of substations with this protocol.

SICAM PAS can establish the dial-up con-nection to the substation either cyclically oras required (e.g. for command output). Bycontrast, the substation can also establish aconnection cyclically or in event-triggeredmode.

Analog or ISDN modems can be used. AGSM modem can also be used in the sub-station.

Several modems are supported for com-munication with substations. Even if the‘standard modem’ is already in use, othersubstations remain accessible.

IEC 60870-5-104 (Master)

Furthermore, connection of substationsis also supported by the TCP/IP-basedIEC 60870-5-104 protocol.

PROFIBUS DP

PROFIBUS DP is a highly powerful fieldbus protocol based on the token passingmethod. For example, it is used for indus-trial automation and for automating thesupply of electricity and gas.

PROFIBUS DP serves to interface multi-functional measuring instruments such asSIMEAS P (I, V, P, Q, p.f. (cos ϕ)) or, forexample, to connect ET200 componentsfor gathering messages and for simplecommands. Messages, for example, can bederived from the signaling contacts of fuseswitch-disconnectors.

For simple applications that do not needfunctions like time synchronization and faultrecording transfer, etc., SIPROTEC 4 unitscan also be interfaced via PROFIBUS DP.

IEDs and substations can also be con-nected with DNP V3.00 (serial and“over IP”) and MODBUS.

ILSA Protocol

Communication via the ILSA protocol is ahighlight of SICAM PAS system. ExistingLSA central devices can be used withoutchanging of configuration on bay level.A future-proof extension with IEC 61850is possible.

System control center connections,distributed process connection and processvisualization

SICAM PAS operates on the basis of Win-dows 2000, Windows XP Professional andWindows XP Embedded. This means thatthe extensive support which 2000/XP offersfor modern communication protocols isalso available with SICAM PAS.SICAM PAS was conceived for easy and fastintegration of conventional protocols.Contact Siemens if you have any questionsabout integration of user-specific protocols.

The standardized telecontrol protocolsIEC 60870-5-101, IEC 60870-5-104 andDNP V3.00 (which is also used throughoutthe world) are supported for the purposeof linking up to higher-level system controlcenters.

Asymmetric encryption enables tap-proofDNP V3.00 communication via TCP/IPconnection to higher-level control centers.

Distributed process connection in the sub-station is possible thanks to the SICAMPAS Device Interface Processor (DIP).

SICAM PAS can also be set up on comput-ers networked with TCP/IP. Here, onecomputer performs the task of the so-called full server. Up to six other comput-ers can be used as DIPs. With this architec-ture, the system can be adapted to thetopological situation and its performancealso boosted.

SICAM PAS allows use of the SICAM PAS CCprocess visualization system for centralprocess control and monitoring.

For industrial applications, it is easy toconfigure an interface to process visualiza-tion systems via OPC (object linking andembedding for process control).SICAM PAS can be configured as an OPCserver or as an OPC client.The SICAM PAS process variables – avail-able with the OPC server – can be read andwritten with OPC clients working either onthe same device or on one networked byTCP/IP. This mechanism enables, for ex-ample, communication with another pro-cess visualization system.The OPC server is included in the basicsystem.

The OPC client can read and write datafrom other OPC servers. Typical applica-tions are data exchange with anotherSICAM PAS station unit, and the connec-tion of SIMATIC programmable control-lers.The OPC client is available as an optionalpackage.

Automation

SICAM Diamond

SICAM Diamond can be used to monitorthe system interfaces, to indicate switchingdevice states (and up-to-date measuredvalues), and also for further diagnosticpurposes.SICAM Diamond features an event list andenables the issue of switching commands.SICAM Diamond allows access to datawith a Web browser (Microsoft InternetExplorer), either on the same computer orfrom a Web client.I addition to this, a fault recording archivecreated with SICAM Recpro can be accessedvia the intranet/Internet using SICAMDiamond for visualization, analysis anddownloading of the fault recordings.

In other words:SICAM PAS permits data access withWeb-based programs.

Further station control aspects

SICAM PAS features bay blocking andtelecontrol blocking functions.The telecontrol blocking function can alsobe configured for specific channels so as toprevent the transfer of information to oneparticular control center during operation,while transfer continues with other controlcenters. The bay blocking and telecontrolblocking functions act in both the signalingand the command directions.

Channel-specific switching authority alsomakes it possible to distinguish betweenlocal control (SICAM PAS CC) and remotecontrol for the switching direction, butalso between control center connections.

Circuit-breakers can be controlled insynchronized/unsynchronized mode.

Automation tasks

can be configured in SICAM PAS with theCFC (Continuous Function Chart), whichconforms to IEC 61131. In this editor,tasks are configured graphically by wiringfunction blocks. SICAM PAS comes withan extensive library of CFC functionblocks, developed and system-tested spe-cially for energy automation.

Applications range from generation ofsimple group indications through switch-ing interlocks to complex switching se-quences.

Namely creation of switching sequencesare supported by the SFC Editor(Sequential Function Chart).

Redundancy

The SICAM PAS station unit can be usedin a duplicate configuration to furtherboost the availability of the station controllevel (see Fig. 14/3). This duplication ispossible with IEDs or substation devicesthat support simultaneous communicationwith two masters (PROFIBUS FMS,IEC 60870-5-101) or clients (IEC 61850).

A redundant structure is also possible forprocess visualisation with SICAM PAS CCand fault-record archiving with SICAMRecpro as shown in Fig. 14/3.

Scope of information

The amount of information to beprocessed by SICAM PAS is essentiallydetermined by the following factors:

• Computer network concept(multiple-computer network orsingle-station system)

• Performance data of the hardware used

• Performance data of the network

• Size of the database (RDBMS)

• Rate of change of values

With a distributed PAS system using afull server and up to 6 DIPs a maximumof 350 IEDs and 20,000 data points canbe supported.

Process Visualization

Process visualization with SICAM PAS CC(see also Fig. 14/4)

In the operation of a substation, SICAM PASis used for configuration purposes and as apowerful data concentrator. SICAM PAS CCserves as the process visualization system.

Several independent SICAM PAS CC serv-ers can be connected to one SICAM PAS.Connection of redundant servers is alsosupported. SICAM PAS CC supports theconnection of several SICAM PAS systems.

In the signal lists, the original time stampsare logged in ms resolution as they occur inthe devices. With every signal, a series ofadditional data is also presented to provideinformation about causes (spontaneous,command), event sources (close range, lo-cal, remote), etc. Besides process signals,command signals are also logged.

IndustrialX-Controls are used to controland monitor switchgear. These switchingdevice objects support four different formsof presentation (IEC, DIN, SINAUT LSA,SICAM) for circuit-breakers and discon-nectors. It is also possible to create bitmaps(defined for a specific project) to representswitching devices, and to link them to theobjects. For informative visualization, notonly nominal and spontaneous flashing aresupported, but also the display of variousdevice and communication states (e.g. up-to-date/not up-to-date, bay and telecontrolblocking, etc.).

Measured values and switching device statesthat are not continuously updated due to,e.g., device or communication failure or bayblocking, may be updated directly via theoperation panel with SICAM PAS CC.

In conjunction with the SICAM PAS stationunit, the switching devices can be controlledeither directly or with “select before operate”.

When visualizing the process by single-lineimages, topological coloring can be used.

The WinCC Add-on SIMATIC Web navi-gator can be used for control and monitor-ing via the Internet.

SICAM Valpro can be used to evaluatemeasured and metered values. It not onlyallows a graphical and a tabular display ofarchived values, but also enables subse-quent evaluation functions such as min-ima, maxima and averages (on an hourlyor daily basis).

SICAM Recpro supports automatic retrievaland archiving of fault recordings from protec-tion units connected with IEC 60870-5-103,PROFIBUS FMS and IEC 61850.

SICAM PAS CC is based on SIMATICWinCC, which has advanced to becomeboth the industrial standard and the mar-ket leader in Europe. It has the followingimpressive features:

• Multilingual capability

• All operation and monitoring functionson-board.These include not only the graphics sys-tem for plant displays and the signalingand archiving system for alarms and mea-sured values, but also a reporting andlogging system. Further advantages areintegrated user administration, along withthe granting and checking of access rightsfor configuration and runtime operations.

• Easy and efficient configurationConfiguration is assisted by dialogs,wizards and extensive libraries.

• Consistently scalable, even via the WebIn conformity with requirements, thebandwidth ranges from simple single-userstation through to distributed multi-usersystems with redundant servers andmulti-site solutions with Web clients.

• Open standards for easy integrationUsing any external tools, archived datacan be accessed through a series of openinterfaces (such as SQL and ODBC) forfurther editing.Manufacturer-independent communicationwith lower-level controllers (or with appli-cations such as MS Excel) is supported withOPC (OLE for Process Control).Visual Basic for Applications (VBA),VBScript or ANSI-C create an ideal scopefor project-specific solutions.

• Expandable with options and add-ons

− WinCC/Dat@Monitorserves to display and evaluate current pro-cess states and historical data on office PCs,using standard tools such as the MicrosoftInternet Explorer or Microsoft Excel

− WinCC/Web Navigatoris an option with SIMATIC WinCC forcontrolling and monitoring systems overthe Internet, a company Intranet or a LAN

− WinCC/Connectivity PackThe functions of the two OPC serversHDA and A&E, and of the WinCCOLE-DB provider are ensured by theWinCC/Connectivity Pack.

− FunkServerProWith the aid of FunkServerPro, messagesfrom the WinCC signaling system can beforwarded automatically to radio call re-ceivers.

Configuration

Overview of the operator controlphilosophy and user interface

The SICAM PAS user interface is based oncustomary Windows technology, whichenables you to navigate in the familiar Win-dows environment both when configuringthe system and during ongoing operation.

The system distinguishes between configu-ration and operation of a substation. InSICAM PAS, these two tasks are firmlyseparated by two independent programs.

The SICAM PAS UI – Configurationprogram is used to create and edit aproject-specific configuration. To enhanceclarity, four views are distinguished:− Configuration

− Mapping

− System topology

− Device templates

A common feature of all views is that theyhave an Explorer window that shows thesystem configuration in a clearly arrangedtree structure. As in the Windows Explorer,you can open individual levels of this treestructure to work in them. Meanwhile, youcan close other levels to improve clarity.

Depending on the level you are currentlynavigating in and the component you havechosen, in the context menu (right mousebutton) SICAM PAS offers you preciselythose program functions that are currentlyappropriate.

You work through the necessary steps inthe data window on the right. Here, you setparameters, select information and defineassignments to a user-specific, process-oriented system topology.

The user interface is uncomplicated andstructured according to the task definition,so as to enable intuitive working and tosimplify changes. The user interface assiststhe editing process by displaying parameterdescriptions and messages when incorrectparameters are entered.

In the tabular views for informationassignment and allocation to the systemtopology, configuration is made easy byextensive sorting and filtering mechanisms,multiple choices and Drag & Drop.

To ensure data consistency and to avoidredundant data input, SICAM PAS UIprovides extensive import and exportfunctions for the exchange of configura-tion data, e.g. with the bay control leveland with process visualization.

Application

The following figures show the most im-portant applications of the SIPROTECIO-Box 6MD61.

The configuration shown in Fig. 14/9 al-lows direct GOOSE communication be-tween the SIPROTEC 4 units (6MD66,7SJ63) and the IO-Boxes, independent ofthe substation controller. Of course, thisconfiguration is also possible without sub-station controller. The IO-Box is used asadditional digital inputs and measure-ments (measurements only with 6MD612),and serves as an additional command out-put.The communication between IO-Box andthe substation controller is established byusing the IEC 61850 standard protocol.

Fig. 14/10 shows a configuration in whichthe IO-Box is used as a central process con-nection in the cubicle of the substationcontroller. For example, cubicle signalinglamps or a signaling horn are controlled bythe command relays of the IO-Box.

Fig. 14/11 shows the communication forsubstations with no Ethernet protocolused. In this case, all communication linesgo directly to the substation controller. Ifinformation from the IO-Box is used forswitchgear interlocking, the interlockinglogic must be part of the substation con-troller.

Communication

With regard to communication betweencomponents, particular emphasis is placedon the SIPROTEC 4 functions required forenergy automation.

• Every data item is time-stamped at itssource, i.e. where it originates.

• Information is marked according towhere it originates from (e.g. if a com-mand originates “local” or “remote”)

• The feedback to switching processes isallocated to the commands.

• Communication processes the transferof large data blocks, e.g. file transfers,independently.

• For the reliable execution of a com-mand, the relevant signal is first ac-knowledged in the unit executing thecommand. A check-back indication isissued after the command has been en-abled (i.e. interlocking check, target =actual check) and executed.

In addition to the communication inter-faces on the rear of the unit, which areequipped to suit the customer’s require-ments, the front includes an RS232 inter-face for connection of DIGSI. This is usedfor quick diagnostics as well as for theloading of parameters. DIGSI 4 can readout and represent the entire status of theunit online, thus making diagnostics anddocumentation more convenient. It is inprinciple possible to implement othercommunication protocols upon request.

Control

The bay control units of the 6MD66 serieshave command outputs and indicationinputs that are particularly suited to therequirements of high-voltage technology.As an example, the 2-pole control of aswitching device is illustrated (see Fig.14/18). In this example, two poles of thecircuit-breaker are closed and 1 pole isopen. All other switching devices(disconnectors, earthing switches) areclosed and open in 1½-pole control.A maximum of 14 switching devices canbe controlled in this manner.

A complete 2-pole control of all switchingdevices (see Fig. 14/19) is likewise possible.However more contacts are required forthis. A maximum of 11 switching devicescan be controlled in this manner.

Fig. 14/19 2-pole connection diagram of circuit-breakers and disconnectors

A possible method to connect the switch-ing devices to the bay control unit 6MD66is shown in Fig 14/20. There it is shownhow three switching devices Q0, Q1, andQ2 are connected using 1½ pole control.

Siemens SIP · 2008

14/23

Functions

Using the CFC (Continuous FunctionChart) available in all SIPROTEC 4 units,the bay interlock conditions can, amongother things, be conveniently configuredgraphically in the 6MD66 bay control unit.The inter-bay interlock conditions can bechecked via the “inter-relay communica-tion” (see next section) to other 6MD66devices. With the introduction ofIEC 61850 communication, the exchangeof information for interlocking purposes isalso possible via Ethernet. This is handledvia the GOOSE message method. Possiblepartners are all other bay devices or protec-tion devices which support IEC 61850-GOOSE message.

In the tests prior to command output, thepositions of both key-operated switches arealso taken into consideration. The upperkey-operated switch corresponds to the S5function (local/remote switch), which is al-ready familiar from the 8TK switchgear in-terlock system. The lower key-operatedswitch effects the changeover to non-interlocked command output (S1 func-tion). In the position ”Interlocking Off”the key cannot be withdrawn, with the re-sult that non-operation of the configuredinterlocks is immediately evident.

The precise action of the key-operatedswitch can be set using the parameter”switching authority”.

With the integrated function ”switchgearinterlocking” there is no need for an exter-nal switchgear interlock device.

Furthermore, the following tests are imple-mented (parameterizable) before the out-put of a command:

• Target = Actual, i.e. is the switching de-vice already in the desired position?

• Double command lockout, i.e. is an-other command already running?

• Individual commands, e.g. earthingcontrol can additionally be secured us-ing a code.

Functions

The bay control unit can, upon closing ofthe circuit-breaker, check whether the syn-chronization conditions of both partialnetworks are met (synchro-check). Thusan additional, external synchronization de-vice is not required. The synchronizationconditions can be easily specified using theconfiguration system DIGSI 4. The unitdifferentiates between synchronous andasynchronous networks and reacts differ-ently upon connection:

In synchronous networks there are minordifferences with regard to phase angle andvoltage moduli and so the circuit-breakerresponse time does not need to be takeninto consideration. For asynchronous net-works however, the differences are largerand the range of the connection window istraversed at a faster rate. Therefore it iswise here to take the circuit-breaker re-sponse time into consideration. The com-mand is automatically dated in advance ofthis time so that the circuit-breaker con-tacts close at precisely the right time.Fig. 14/21 illustrates the connection of thevoltages.

As is evident from Fig. 14/21, the synchro-nization conditions are tested for onephase. The important parameters forsynchronization are:

|Umin| < |U| < |Umax|(Voltage modulus)

Δ < Δ max

(Angle difference)

Δf < Δfmax

(Frequency difference)

Using the automation functions availablein the bay control unit, it is possible toconnect various reference voltages depend-ing on the setting of a disconnector. Thusin the case of a double busbar system, thereference voltage of the active busbar canbe automatically used for synchronization(see Fig. 14/22).

Alternatively the selection of the referencevoltage can also take place via relay switch-ing, if the measurement inputs are alreadybeing used for other purposes.

Synchronization

The bay control unit offers the option ofstoring various parameter sets (up to eight)for the synchronization function and ofselecting one of these for operation. Thusthe different properties of several circuit-breakers can be taken into consideration.These are then used at the appropriatetime. This is relevant if several circuit-breakers with e.g. different response timesare to be served by one bay control unit.

The measured values can be connected tothe bay control unit in accordance withFig. 14/21 (single-phase system) orFig. 14/23 (two-wattmeter circuit).

The synchronization function can beparameterized via four tabs in DIGSI.

Communication

Communication

The device is not only able to communicateto the substation control level via standardprotocol like IEC 61850, IEC 60870-5-103or others. It is also possible to communicatewith other bay devices or protection devices.Two possibilities are available.

Inter-relay-communication

The function “inter-relay-communication”enables the exchange of information direct-ly between 6MD66 bay controller devices.The communication is realized via Port “C”of the devices, so it is independent from thesubstation communication port “B”. Port“C” is equipped with a RS485 interface. Forcommunication over longer distances, anexternal converter to fiber-optic cable canbe used.

An application example for inter-relay-communication is shown in Fig. 14/29.Three 6MD66 devices are used for controlof a 1½ circuit-breaker bay. One deviceis assigned to each of the three circuit-breakers. By this means, the redundancyof the primary equipment is also availableon the secondary side. Even if one circuit-breaker fails, both feeders can be supplied.Control over the entire bay is retained, evenif one bay control unit fails. The three baycontrol units use the inter-relay-communi-cation for interchange of switchgear inter-locking conditions. So the interlocking isworking completely independent from thesubstation control level.

IEC 61850-GOOSE

With the communication standardIEC 61850, a similar function like inter-relay-communication is provided withthe “GOOSE” communication to otherIEC 61850-devices. Since the standardIEC 61850 is used by nearly all SIPROTECdevices and many devices from other sup-pliers, the number of possible communi-cation partners is large.

The applications for IEC 61850-GOOSE arequite the same as for inter-relay-communi-cation. The most used application is theinterchange of switchgear interlocking in-formation between bay devices. GOOSEuses the IEC 61850 substation Ethernet, sono separate communication port is needed.The configuration is shown in Fig. 14/30.The SIPROTEC devices are connected viaoptical Ethernet and grouped by voltagelevels (110 kV and 20 kV). The devices inthe same voltage level can interchange thesubstation-wide interlocking information.GOOSE uses the substation Ethernet.

Fig. 14/30 Connection for IEC 61850-GOOSE communication

Like inter-relay-communication, GOOSEalso supplies a status information for super-vision of the communication. In case ofinterruption, the respective information ismarked as “invalid”.

Therefore, non-affected information stillcan be used for interlocking, and a maxi-mum functional availability is guaranteed.

Functions

Measured-value processing is implementedby predefined function modules, which arelikewise configured using DIGSI 4.

The transducer modules are assigned in theDIGSI 4 assignment matrix to current andvoltage channels of the bay control unit.From these input variables, they form vari-ous computation variables (see Table 14/1).

The individual transducer modules can beactivated in the functional scope of theunit and will then appear in the DIGSI 4assignment matrix with the input channelsand output variables from Table 1. Theoutput variables can then be assigned tothe system interface or represented in themeasured value window in the display.

Functions

The connection of the input channels canbe chosen without restriction. For the two-wattmeter circuit, the interface connectionshould be selected in accordance withFig. 14/33. The two-wattmeter circuit en-ables the complete calculation of athree-phase system with only two voltageand two current transformers.

For internal metering, the unit can calcu-late an energy metered value from themeasured current and voltage values. If anexternal meter with a metering pulse out-put is available, the bay control unit canobtain and process metering pulses via anindication input.

The metered values can be displayed andpassed on to a master unit. A distinction ismade between forward, reverse, active and

reactive power (± kWh, ± kvarh).

With integrated logic, the user can set, via agraphic interface (CFC, Continuous Func-tion Chart), specific functions for the auto-mation of switchgear or substation.Functions are activated via function keys,binary input or via communication inter-face. Processing of internal indications ormeasured values is also possible.

The switching authorization (control au-thorization) (interlocked/non-interlocked,corresponds to key-operated S1 in the 8TKinterlock system) and the switching au-thority (local/remote, corresponds tokey-operated S5 for 8TK) can be preset forthe SIPROTEC 4 bay control unit usingkey-operated switches. The position ofboth keys is automatically evaluated bycommand processing. The key for opera-tion without interlocks cannot be removedwhen in the position “non-interlocked”,such that this mode of operation is imme-diately recognizable (see also page 14/23,Section “Switchgear interlockings”).

Every change in the key-operated switchpositions is logged.

Fig. 14/33Two-wattmeter circuit (connection to bay control unit)

Chatter blocking

Chatter blocking feature evaluates whether,in a configured period of time, the numberof status changes of indication input ex-ceeds a specified figure. If exceeded, the in-dication input is blocked for a certainperiod, so that the communication line tothe master unit will not be overloaded bydisturbed inputs.

For every binary input, it is possible to setseparately whether the chatter blockingshould be active or not. The parameters(number of status changes, test time, etc.)can be set once per unit.

To avoid the transmission of informationto the master unit during works on thebay, a transmission blocking can be acti-vated.

Indications can be filtered and delayed.

Filtering serves to suppress brief changes inpotential at the indication input. The indi-cation is passed on only if the indicationvoltage is still present after a set period oftime.The filter time can be set from 0 to 24hours in 1 ms steps. It is also possible to setthe filter time so that it can, if desired, beretriggered.

Furthermore, the hardware filter time canbe taken into consideration in the timestamp; i.e. the time stamp of a message thatis detected as arriving will be predated bythe known, constant hardware filter time.This can be set individually for every mes-sage in a 6MD66 bay control unit.

Auto-Reclosure (ANSI 79)

The 6MD66 is equipped with anauto-reclosure function (AR). The func-tion includes several operating modes:

• Interaction with an external device forauto-reclosure via binary inputs and bi-nary outputs; also possible with interac-tion via IEC 61850-GOOSE

• Control of the internal AR function byexternal protection

• 3-pole auto-reclosure for all types offaults; different dead times are availabledepending on the type of the fault

• 1-pole auto-reclosure for 1-phase faults,no reclosing for multi-phase faults

• 1-pole auto-reclosure for 1-phase faultsand 2-phase faults, no reclosing formulti-phase faults.

• 1-pole auto-reclosure for 1-phase and3-pole auto-reclosure for multi-phasefaults

• 1-pole auto-reclosure for 1-phase faultsand 2-phase faults and 3-phase auto-reclosure for multi-phase faults

• Multiple-shot auto-reclosure

• Interaction with the internal synchro-check

• Monitoring of the circuit-breaker auxil-iary contacts

In addition to the above-mentioned oper-ating modes, several other operating prin-ciples can be employed by means of theintegrated programmable logic (CFC).Integration of auto-reclosure in the feederprotection allows the line-side voltages tobe evaluated. A number of voltage-depend-ent supplementary functions are thusavailable:

• DLCBy means of dead-line-check (DLC),reclosure is effected only when the line isdeenergized (prevention of asynchron-ous breaker closure)

• ADTThe adaptive dead time (ADT) is em-ployed only if auto-reclosure at the re-mote station was successful (reductionof stress on equipment).

• RDTReduced dead time (RDT) is employedin conjunction with auto-reclosurewhere no teleprotection method is em-ployed: When faults within the zone ex-tension but external to the protected lineof a distance protection are switched offfor rapid auto-reclosure (RAR), the RDTfunction decides on the basis of measure-ment of the return voltage from the re-mote station which has not trippedwhether or not to reduce the dead time.

Breaker failure protection (ANSI 50BF)

The 6MD66 incorporates a two-stage cir-cuit-breaker failure protection to detectfailures of tripping command execution,for example, due to a defective circuitbreaker. The current detection logic isphase-selective and can therefore also beused in single-pole tripping schemes. lf thefault current is not interrupted after asettable time delay has expired, a retripcommand or a busbar trip command willbe generated. The breaker failure protec-tion can be initiated by external devices viabinary input signals or IEC 61850 GOOSEmessages.

The 6MD66 bay control units can, like theother units in the SIPROTEC 4 range, beprovided with the current time by a num-ber of different methods:

• Via the interface to the higher-level sys-tem control (PROFIBUS FMS orIEC 61850)

• Via the external time synchronization in-terface on the rear of the unit (variousprotocols such as IRIG B and DCF77 arepossible)

• Via external minute impulse, assigned toa binary input

• From another bay control unit by meansof inter-relay communication

• Via the internal unit clock.

DIGSI 4 Configuration tool

The PC program DIGSI 4 is used for theconvenient configuration of all SIPROTEC4 units. Data exchange with the configura-tion tool plusTOOLS of the energy auto-mation system SICAM is possible, suchthat the bay level information needs onlybe entered once. Thus errors that couldarise as a result of duplicated entries are ex-cluded.

DIGSI 4 offers the user a modern and intu-itive Windows interface, with which theunits can be set and also read out.

The DIGSI 4 configuration matrix allowsthe user to see the overall view of the unitconfiguration at a glance (see Part 3,Fig. 3/2). For example, all allocations of thebinary inputs, the output relays and theLEDs are shown at a glance. And with oneclick of the button, connections can beswitched. Also the measuring and meteringvalues are contained in this matrix.

Special attention has been paid to commis-sioning. All binary inputs and outputs canbe read and set directly. This can simplifythe wire checking process significantly forthe user.

CFC: Reduced time and planning for pro-gramming logic

With the help of the CFC (ContinuousFunction Chart), you can configure inter-locks and switching sequences simply bydrawing the logic sequences; no specialknowledge of software is required. Logicalelements, such as AND, OR and time ele-ments, measured limit values, etc. areavailable.

Display editor

A convenient display editor is available todesign the display on SIPROTEC 4 units(see Part 3, Fig. 3/6). The predefined sym-bol sets can be expanded to suit the user.Drawing a single-line diagram is extremelysimple. Operational measured values (ana-log values) in the unit can be placed whererequired.

In order to also display the comprehensiveplant of the high-voltage switchgear andcontrolgear, the feeder control display ofthe 6MD66 bay control unit can have anumber of pages.

Fig. 14/35CFC plan for interlocking logic (example)

Fig. 14/36General configuration view of the bay control unit

In this process, several pages of a controldisplay can be configured under one an-other, and the user can switch betweenthem using the cursor. The number ofpages, including the basic display and thefeeder control display, should not exceed10, as otherwise the memory in the unitwill be completely occupied.

Fig. 14/36 illustrates the general view of the6MD66 bay control unit on the DIGSI 4configuration interface.

As is the case with the SIPROTEC 4 pro-tection units, there is an icon called “Func-tional Scope”. It enables the configurationof measured-value processing and the syn-chronization function and the protectionfunctions (auto-reclosure and breakerfailure protection).
