  1. REAL TIME DIGITAL SIMULATION GOOSE and SV with RTDS

  2. GOOSE and SV with RTDS Presentation Outline: • 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

  3. 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 The World Standard for Real Time Digital Power System Simulation

  4. RTDS Simulation Hardware RTDS Hardware • Custom parallel processing computer • Modular hardware design • A unit of hardware is called a ‘Rack’ and typicallyincludes: • 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 The World Standard for Real Time Digital Power System Simulation

  5. 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 The World Standard for Real Time Digital Power System Simulation

  6. 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

  7. 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

  8. 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

  9. 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 The World Standard for Real Time Digital Power System Simulation

  10. 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

  11. 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 The World Standard for Real Time Digital Power System Simulation

  12. GTNET-GSE • GTNET Component Library GTNET_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 The World Standard for Real Time Digital Power System Simulation

  13. GTNET-GSE • GTNET_GSE SCD 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 The World Standard for Real Time Digital Power System Simulation

  14. GTNET-GSE GTNET_GSE SCD Editor The World Standard for Real Time Digital Power System Simulation

  15. 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 The World Standard for Real Time Digital Power System Simulation

  16. GTNET IEC 61850 Test Testing IEC 61850 Closed-Loop Relay Testing Demonstration The World Standard for Real Time Digital Power System Simulation
