Hardware-in-the-Loop Testing for Protective Relays Using Real Time Digital Simulator (RTDS)

With the increasing size and complexity of power systems, it is crucial to have an effective protection system in place ensure its reliability. One important components are relays. It for a relay operate dependably securely so that any fault can be cleared time minimize damages network. However, test realistic environment before commissioning Testing actual network expensive with limited scenarios. Hence, Hardware-in-the-Loop (HIL) testing efficient method perform closed-loop since numerous cases simulated provide operating under test. This paper sheds light on HIL done protective relays using sample distribution RTDS. Two SEL-351 been used this experiment, proper settings calculated coordination. The also describes procedure configuring other RTDS interfacing After setup, pre-fault, fault, post-fault analysis was system. results obtained from these analyses cross-checked event history two relays, AcSELerator Quickset software. provides thorough information researchers replicate presented study or develop new experiments. help developing fundamental understanding setup further applied more complex
