The real-time digital simulator lab provides real-time dynamic simulation of system faults, sequence of events, and/or conditions such as power swings, open poles, out of step conditions and other fault and system conditions. Relay responses can then be observed in a real closed loop environment to prove the relay's performance within the customer's system.
Real Time Digital Simulator
Real-time digital simulator labs are used to perform real time closed loop testing of protection, control and relay communications equipment. The power system models for testing are developed from customer system data and components including transmission lines, transformers, generators, reactors, current and voltage transformers (CTs and VTs). Interaction between relays, breakers and communication equipment is simulated during power system disturbances to verify and fine-tune relay settings. GE Digital Energy senior engineers will be available for lab time. The following schemes and applications can be tested using the digital simulator:
Line Protection
- Two and three terminal distance or current differential protection
- MOV protected series-compensated lines
- Single-pole tripping applications
- Single-pole tripping applications
- Simulation of power system phenomenon affecting the behavior of protective relays such as power swings, frequency excursions, evolving/sequential/cross-country/resistive faults, etc.
- Current differential protection and distance relay pilot-aided schemes using actual communication equipment such as multiplexers, PLCs and modems
Transformer Protection
- 2 and 3 winding transformers with on-load tap changers
- 2 and 3 winding autotransformers
- Split-phase transformers
- Phase and angle regulating transformers
- Turn-to-turn faults, saturation and hysteresis phenomenon
AC Rotating Machine Protection
- Synchronous Generators complete with excitation system, stabilizer and governor turbine model
- Induction Generators
- Generator relay testing on a made-to-scale physical generator simulator
Busbar Protection
- Up to 12 single-phase or 4 three-phase circuit with bus-replica for double bus arrangement
- Breaker Failure simulation
ATP/EMTP Case Studies
ATP/EMTP case studies using detailed modeling techniques for medium voltage networks through extra high voltage generation, transmission and distribution systems.
Playback Test
Playback testing of recorded waveforms or ATP/EMTP simulations to protective relays to verify the intended operation and response of the device.
Testing & Verifying Relay Settings
With the customers relay or setting file the service includes upgrading firmware and uploading new setting files, testing relay settings and documenting test results.
