Demo | Traveling Wave Relay Testing with FPGA-based Real-Time Simulator | OPAL-RT Learning Journey

Author : Shijia Li

Watch a demonstration on how to use a real-time simulator to perform Hardware-in-the-Loop (HIL) testing of the latest Traveling Wave Fault Locators. The model of a power system network including a long transmission line is executed in real-time on FPGA at a time step of hundreds of nanoseconds. Low-power analog signals are sampled at 1MHz from the RTS and injected to two SEL-T400L relays. Various fault scenarios are applied to test the TW87 fault locating algorithms.
