RTDS Simulation Software

RSCAD

  • Includes everything required for simulation studies

  • No additional add-on modules required for any aspects of simulation

  • No 3rd party modules

  • Site license and one maintenance agreement

Gtnet

GTNET

GTNET Card

  • Network Interface Card

  • Used to interface a number of different network protocols with RTDS simulator

  • Currently supports

    • GSE – IEC 61850 GOOSE/GSSE

    • SV – IEC 61850 9-2LE (Sampled Measured Values)

    • PMU – IEEE C37.118 data stream output

    • DNP3 – Distributed Network Protocol

    • IEC 60870-5-104 (104)

    • PLAYBACK – Playback of large data sets

The World Standard for Real Time Digital Power System Simulation


Gtnet sv

GTNET-SV

GTNET Component Library

GTNET-SV

  • Simulates IEC 61850 9-2 LE compliant Merging Unit

  • Two models with different capabilities available in the library

    • GTNET_SV9-2_v5.def

    • GTNET_SV-SE2.def

The World Standard for Real Time Digital Power System Simulation


Gtnet sv1

GTNET-SV

GTNET Component Library

GTNET_SV9-2_v5

  • Compliant with IEC 61850 9-2LE

  • Provides IEC 61850 9-2 Sampled Measured Values communication using GTNET hardware

  • Can be configured to publish up to 2 data streams

    • According to 9-2LE, one data stream shall contain 4 currents and 4 voltages

  • Sample rate at either 80 or 256 samples per cycle

    • 256 samples per cycle applies to one output data stream only

The World Standard for Real Time Digital Power System Simulation


Gtnet sv2

GTNET-SV

  • GTNET Component Library

    GTNET_SV9-2_v5 – Non-9.2LE mode

  • based on IEC 61869-9 and the Chinese National Standard for SV merging units

  • Able to publish one datastream for up to 24 channels of voltages or currents

  • The time delay channel can be configured to the first channel as required in a Chinese merging unit SV datastream

  • Currently supports data rate of 80 samples/cycle

  • Able to achieve the requirement of 10 usec of jitter between samples

Gtnet sv3

GTNET-SV

  • GTNET Component Library

    GTNET_SV9-2_v5 – Input Mode

  • Can be configured to subscribe 1 data stream from 1 MU at 80 or 256 samples per cycle

  • GTSYNC is needed for use of the GTNET_SV9-2_v5 component

The World Standard for Real Time Digital Power System Simulation


Gtnet sv4

GTNET-SV

  • GTNET Component Library

    GTNET_SV-SE2

  • Developed to have customized functions for Alstom Grid (UK)

    • Only supports 1 SV output data stream at 80 samples per cycle

    • Change chronological order of Samples (packets)

    • Packet delay

    • Packet loss

    • Jitter algorithm

  • Provides more flexibility for testing MUs

GTNET IEC 61850 Test

GTNET Card

Testing

  • IEC 61850 Closed-loop relay testing

    • The interested power system is simulated in RTDS

    • Bus voltages and breaker currents at certain location are sent to the external physical IEDs (IEC 61850 9-2LE or 61869-9 compatible) through SV messages

    • Breaker status and tripping/reclosing signals are exchanged through GOOSE messages
