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

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 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
