In this paper the studies of the performance of feeder distance protection with multiple installations of static synchronous compensator (STATCOM) is presented. Detailed representation of delta-connected multi-level modular converter (MMC) STATCOM is modelled and its impact on feeder distance protection is analytical studied. A Real-Time Digital Simulation (RTDS) based Hardware-in-the-Loop (HIL) testing platform is established using practical distance relays, multiple detailed MMC STATCOM models and realistic transmission data. Different types of internal/external faults at varying locations are simulated to investigate the STATCOM’s impact on feeder distance protection.
