Introduction to RTDS Network Interface Card GTNET-GSE GTNET-SV IEC 61850 applications

in RTDS Question and Answer

The World Standard for Real Time Digital Power System Simulation


RTDS Technologies Inc.

Background and History: Technical Advisory Board (sponsors)

RTDS Development Project initiated in 1986

Major Funding from Manitoba Hydro

World’s 1st real time HVDC simulation was achieved in 1989

Continued development and refinement to produce a commercial product

1st commercial installation in 1993

RTDS Technologies created in 1994



RTDS Simulation Hardware

RTDS Hardware Custom parallel processing computer

Modular hardware design• A unit of hardware is called a ‘Rack’ and typically includes:• 2~6 RISC PB5 Processor Cards • 1 Giga Transceiver Workstation InterFace Card (GTWIF)

Main interface with the hardware is through user-friendly software

Ample, convenient input and output allowing connection of physical devices



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 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 Component LibraryGTNET-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



GTNET-SV

GTNET Component LibraryGTNET_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 onlyThe World Standard for Real Time Digital Power System

Simulation


GTNET-SV

GTNET Component LibraryGTNET_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-SV

GTNET Component LibraryGTNET_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



GTNET-SV

GTNET Component LibraryGTNET_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-GSE

GTNET Component LibraryGTNET_GSE

GTNET_GSE_v5.def Provides IEC 61850 GOOSE communications Supports up to 4 TX/RX modules, which can be arranged to

simulate 1-4 IEDs (i.e. 1 IED with 4 modules, 4 IEDs each with 1 module…)

Each module can publish up to 64 points (stVal) (Boolean, or INT32, or FLOAT32, or Dbpos), or 32 points with Quality

Each module can subscribe up to 32 points (16 Booleans) with Quality

Can subscribe GOOSE message from up to 16 unique external IEDs



GTNET-GSE

GTNET_GSESCD Editor

A software tool to generate the required configuration file

The configuration file defines the capabilities of the interconnected devices

Provides a mechanism for the user to create and edit a Substation Configuration Description (SCD) file

Includes an interface for mapping the external references to the GTNET inputs

Loads existing SCD files to import ICD/CID files

Exports GTNET ICD file

GTNET IEC 61850 Test

GTNET CardTesting 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
