Abstract:
The goal of this effort is to determine how a real-time digital simulator (RTDS) can be used to simulate the behavior of a remedial action scheme (RAS) in a controlled laboratory environment at the Southern California Edison (SCE) Power Systems Laboratory. The RAS functions with two redundant pairs: System A and System B. The lab test setup includes all actual RAS System A relays and all simulated System B relays. The RTDS scripting capability automates more than 9,000 tests that span various contingencies, arming levels, load flows, and A/B system availability. The simulator demonstrated the ability to re-create an existing RAS in the laboratory environment, which will be a valuable tool in preparing for future RAS
applications.
