2 Presentation Outline:  Introduction to RTDS  Network Interface Card  GTNET-GSE  GTNET-SV  IEC 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 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 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 3 rd 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 GOOSE/GSSE  SV – IEC LE (Sampled Measured Values)  PMU – IEEE C data stream output  DNP3 – Distributed Network Protocol  IEC (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 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 LE  Provides IEC 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 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 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 Test GTNET Card Testing  IEC 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 LE or 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
