Merit’s Traction SCADA for IndianRailways

Keeping the critical requirements of the Railways in mind, MERIT has developed the standard electric traction SCADAsoftware (Traction scada) on the Windows platform to control and monitor 25 KVA Traction power line ( more than 30substation spread over more than 300 km per installation ) by the railway operator from a centralized Remote ControlCenter ( RCC ).

Pioneers in Railway SCADA :

MERIT is one of the few organizations who have been supplying Traction SCADA system to the INDIANRAILWAYS, since the past 11 years with more than 14 successful installations. Virtually any requirement of SCADA system in railways is synonymous with MERIT.

Beginning with IRTU 3000/4000 (Technology Transferred from ALS-USA) system, MERIT has progressively

offered the railways, a SCADA system that is the software developed in Latest WINDOWS Platform and RTUOff latest Phillips Microcontroller based PLC , technologically up to date with the best in the world.

Major Subsystems of SCADA:

Remote control center ( RCC ) : Consisting of 10 computers Named as Master, standby, FEP and OWS ( Operator work station ) computers connected in dual local area network , The Overall SCADA Software has been split in todifferent subsystems and loaded in the above named computers to perform their Specific Task

Remote Terminal Unit ( RTU ) : Merit Make RTU consisting of Micro controller based PLC ( CPU, DI , DO and AI ) ,Power Supply, Catnery Modules, Contactors, MODEM and Energy Meter installed in various Substation like SP, SSP ,FP and TSS collect the data relating to substation like Voltage, current , MD, PF, Open or Close Status of BM/CB’S ,Catnery ..etc and perform the control operation like OPEN/CLOSE the BM and CB’S , Transformer Tape Changing ..etc

as per the requirement of the operator From Remote control center ( RCC). The WAN communication between RCCand Various RTU is through Line Modem as well as through GSM.

Major Features of Traction SCADASystems:

The software consists of a set of closely interacting software modules that carry out the functions of real-time data

acquisition and supervisory control, data processing, handling operator interactions and report generation.

The functions of the SCADA system are:

• Acquiring Analog and digital data from field equipment

• Processing the acquired data Generating online alarms and events

• Control of circuit breakers and Interrupters located in the sub-station and switching stations

• Logging the data relating to the field inputs in to the database

• Presenting the on line Graphical display of BM , CB and Catnery Positions

• Generating alarm, event reports and graphical reports for Voltage, current, PF and MD

• Automatic localization of faults

Traction scada software sub process:

• FEP Process

• Control process

• Network Process

• FTX Process

• DBS Process

•

OWS Process

FEP Process:

This sub-system resides in the FEP Computer. It handles data acquisition from and control to the field.Tele-metered parameters like voltage and current are captured using remote terminal units (RTUs), whichare connected to suitable field instrumentation like meters, transducers, etc. The acquired data is processedto make it relatively protocol-free and is updated in the local database. The changed data (report byexception) is sent to the main sub-system.

The dual-redundant FEP provides a high reliability to the field interface. When the host system fails, the

FEP continues to acquire data from the field and buffers it locally. After the re-establishment of communication with the host, this buffered data is uploaded. This provides the end-user with the exacttiming details of status events.

8/6/2019 54930127 Merit Profile


CONTROL Processes:

Some of the analog, discrete and accumulated values received from the field may be raw values. They are

converted to engineering values, based on pre-defined equations, using linear, non-linear look-up tables.Each point in the system can have a separate equation depending on its field connectivity. The calculatedvalues are also checked for their validity. Reasonable values are passed on for further processing.

NETWORK Processes:

This is process control and monitor the data transfer between various subsystems through TCP/IP andassigning the priory in data transfer between data loging and control output enabling process.

FTX Processes:

The system has a high degree of fault-tolerance, to handle failures at various levels in the hardware andsoftware modules. Redundancy is provided for all critical modules of hardware, such as FEP, master system and software modules. If critical components fail — including a critical software task in the activesystem — the standby system takes over within a few seconds.

DBS Processes:

Logging the Various field parameters and generating the report as per the requirement is controlled by this process . Allthe analog , event and alarm data’s from the field is getting logged in a powerful SQL Database and this process

generates reports on system data. The software supports easy report configuration, with which a set of newreports can be configured for each application. The operator can create and print reports on any loggeddata, on demand. The system can be configured for periodic automatic printing of certain reports.

OWS Processes :

Monitoring and control of the user interactions with the field, is done through the Operator interface console(OWS ). This full-graphic user-friendly interface provides acquired data through single line diagrams andtabular formats.

The MMI is based on a Windows graphical user interface (GUI). It supports features like concurrent displayof multiple windows, resizing and positioning of windows, and multiple page display screens with scrolling.

This display consists of a real-time data presentation to the operator in full-graphic pictorial form, single linediagrams / schematics, tables, lists, icons, graphs, text, user-defined symbols and dynamic data display.

Dynamic data on these pictures and tables are updated with the latest data on change.
