​An FPGA-based HIL testing solution for Traveling Wave Fault Locators

This case-study is to demonstrate how to use the Real-Time Simulator (RTS) to perform Hardware-In-the-Loop 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.
