2.1 SCADA-TE functions

SCADA-TE is mainly designed to manage the power traction infrastructure for metro, light rail and

traditional railways. In simple words, SCADA-TE enables Customer to operate the remote control

of power lines and all ancillary equipment (for example: switches, interlocking devices, alarms,

signals, energy stations).

In such systems, the Operations Control Center (OCC) is the heart for the railway system. Thequalified staff members working in the OCC are responsible for the overall control and commandof the system including all stations and all ancillary subsystems to achieve the goals of CompanyMission Statement. In degraded and emergency situations the control and command can beestablished from the fall back control room to continue the smooth train service.

SCADA-TE SW platform is based on Client/Server architecture which allows the data to be

acquired, managed and displayed on the same or on different network nodes.

Main functionalities provided by the system are listed in the following:

- Acquiring information from peripheral devices and subsystems (remote monitoring)

- Sending commands to peripheral devices (remote control)

- Giving an overall view of the state of the system in real time by synoptic means

- Providing a detailed view of the system by means of video pages displaying:

- power sub-stations

- power networks

- Recording of chronological events (Service Journal)

- Inhibiting 'line clear'/'line blocked' signals of switches by means of "counter marking"

- Software "out of scan" or "Simulation" state for devices

- Locking (precautionary action)

- User rights management

- Maintenance & engineering functions.

Furthermore, the following functions may be added to the system:

- Automatic Fault detection

- "Hot – standby” redundant mode

- Telemetry

- Video projection for synoptic panels.

- Interface with other systems

A.S.C. Group


Resilient architectures are available , spanning from single , stand alone, up to three redundant

server with or without additional Disaster Recovery system with real time alignment of the

Primary/Secondary.

SCADA-TE manages a large number of Operator Workstations ( up to 254) with single or multiple

monitor ( up to 4 )

HMI can be accessed from LAN and WAN with traditional and web based Operator Workstations

Different ways of time synchronisation are available: Client NTP over Ethernet and or a GPS

synchronisation

2.1.1 Data acquisitionData are collected by RTUs (Remote Terminal Unit) . SCADA-TE concept is based on “intelligent”

RTUs. Use of RTUs, enables for the implementation of local control logic that can operate even

when the OCC is disconnected due to some fault.

Data coming from the field (via the RTUs) are collected by the Front End. FE is in charge to

manage communication connections, RTUs data alignment and RTUs polling process.

RTU’s can be connected using different transport media and protocols.

Type of media :

- Single , two parallel, ring telecommunication over a copper pair;

- Single Fiber Optic ring or doubled Fiber Optic ring

- Any reliable, deterministic and secure TCP/IP network

Supported protocols are :

- IEC 608870-5-101 or 104

- IEC 61850

- DNP3

- Modbus RTU/Modbus TCP

and many others1.

1 Please see relevant information for available protocols.

A.S.C. Group


Picture 1: double fiber optic ring configuration

Data managed by the RTUs may be of several types as:

• DI = digital Input ( single point or double point entities )

• DO : Digital Output ( simple or double point , CBO ( Check Before Operate) entities

• AI : Analogue Input ( 0-20 mA , 4 – 20 mA , 0 -10 Vcc, etc. )

• Local serial : data coming from Intelligent Electronic Devices (IED) using different types ofprotocols, as for example : Profibus, IEC 61850, IEC 60870-5-103, Modbus, HDLC, SPA

Bus, etc. )

In this context, data acquisition of these signals is operated for field entities as:

▪ High Voltage feeding line ( if present)

▪ Medium Voltage feeding line ;

▪ Group transformer supply line;

▪ Transformers;

▪ Static Conversion groups;

▪ Catenary supply;

▪ Low Voltage cabinet and auxiliary subsystems, battery charger , etc;

▪ Auxiliary breakers;

▪ Switches;

2.1.2 Remote monitoring

Supervision of plant by means of several video terminals providing overall views (Synoptic Panel)and detailed views (Command Pages) of the Power Supply installations;

� Remote control: possibility of remote control for all the devices on the stretch of trackcontrolled;

� Display of the State of Feeders: real time display of the feeders (AT, MT, BT) in relation to thestate of the devices;

� Forcing: possibility of simulating operational status of the devices;

� Device Masking: makes it possible to exclude a device from scan in order to avoid uselessstatus changes display in case of sensors faults.

2.1.3 Alarm management

Several types of alarms may be collected from the field:

▪ Unknown breaker or switch position ( not open & not closed or both at the same time)

▪ Spontaneous status change (Not ordered entity movement) ( for example a breakers ismoving without any command was issued to it )

▪ Equipment faults

▪ Equipment operational alarms

▪ Analogue value exceed normal range value ( for example a temperature or a voltage);

▪ Auxiliary equipment fault

▪ SCADA-TE auto diagnosis fault

Alarm Management includes:

- Alarm Display (optic and acoustic)

- Alarm registration on the Service Journal

- Alarm Display on the Alarm List page from which it is possible to filter and organise viewsof different alarms

- Alarm management from the operator

- Historical recording ;

A.S.C. Group


Picture 2: Alarm List Display

To help prevent alarm cascades, an alarm can be masked by another alarm or by the result of a

logical expression. Alarms can also be temporarily inhibited by the operator or taken out of service

completely using maintenance mode.

Each Alarm Viewer includes a configurable toolbar allowing the operator to display and change the

Alarm Viewer filter, acknowledge, inhibit or switch alarms to maintenance mode, and execute an

action associated with a particular alarm. (For example opening a mimic video page related to the

alarm origin).

Picture 3: Alarm List Display

A.S.C. Group


2.1.4 Remote Command OperationRemote command: possibility of remote command for all devices on the stretch of track controlled.Commands sending requires a specific operator sequence, as follows:

▪ Lock of selected entity ( for example a breaker) . The system checks that the entity isavailable and not already operated locally and / or by another operator.

▪ Action selection : the operator selects required action that he wants perform on selectedentity;

▪ Remote command sending;

▪ Wait for echo : Echo waiting for the entity to reach the requested status and checking of thestatus

▪ Unlock: the entity is free for new actions..

Generation of commands sequences

SCADA-TE enable the operators ( under specific privileges) to define a sequence of commands.This helps operators to issue specific pre - defined commands sequences.

Command can be issued to:

- breakers

- Load-break switches

- disconnectors

2.1.5 Supply ( energised) busbars status calculationVisualisation in real time of the feeders (AT, MT, BT) in relation to the state of the devices.

Based on the electric network topology, a suitable algorithm calculates the voltage status of

busbars, of the overhead contact lines (catenaries) and feeder lines.

Calculations are executed based on entity status (Open / Closed, uncertain), voltage measures on

incoming feeder lines and minimum voltage relays. Thanks to this function, energised status is

clearly displayed to the operators.

Colours are used to represent the energy status of each section. Colours for each state and

colours priority can be easily configured based on Customer preferences.

2.1.6 Chronological event recording (RCE).SCADA-TE enable for recording chronological event. Resolution depend on selected RTU and may

be 1 ms. RTU are synchronised from a central Master Clock located in the Operation Control

Center and it uses a GPS receiver as reference.

2.1.10 Operators account managementUser privilege management: access to the system is managed by a procedure for entering User

Name and Password; each operator has his own access code (User and Password), unique within

the system. A certain profile is attached to each operator. The system can handle more then 4

different types of profile:

▪ Administrator,

▪ TE Operator,

▪ Maintenance Operator,

▪ Training

SCADA-TE implements a specific function to manage privileges of different domain as pergeographical or other criteria. Operator privileges can be managed by the administrator verysimply.

SCADA-TE provides a full management of Users accounts. It includes “single log-on” facilities ( if

not differently required ) and “domain management” that are “area of responsibility” under a

A.S.C. Group


specific user. In such a way , users are involved in information and procedures relevant to his

“area of responsibility” only.

Domain Management

Managed objects ( breakers, transformers, switches, station, etc. ) can be assigned to a specific“”domain”. Up to 10 domain are available. Domain assignment can be based on any criteria as forexample:

- technology

- geographical

- mixed

Domain assignment can be changed during the operation based on the operator request orbased on event.
