RT22 | Substation Automated Training Simulator (SATS) 

As the complexity of today’s power system increases, it is crucial to have a system protection training program that can incorporate evolving changes and mimics a realistic environment. Dominion Energy is developing real-time models to conduct closed-loop tests. The Substation Automated Training Simulator (SATS) infrastructure is composed of a OP5700 simulator, four OP5600 expansion boxes, and 24 Omicron Power Amplifiers, all mounted on five equipment panels. This system is hardwired to protective relay equipment panels and to primary equipment. There are a variety of use cases that can introduce various abnormal scenarios that may be encountered in a real power system. This closed-loop system enables a simulation to seamlessly replicate the power system response while switching primary substation equipment. Beyond that, it also provides a method of validating entire protection schemes including equipment wiring, individual protective relay settings, and overall device coordination.
