Coordination of MMCs With Hybrid DC Circuit Breakers for HVDC Grid Protection [PDF]
IEEE Transactions on Power Delivery, 2019 A high-voltage direct-current (HVDC) grid protection strategy to suppress dc fault currents and prevent overcurrent in the arms of modular multi-level converters (MMCs) is proposed in this paper. The strategy is based on the coordination of half-bridge (HB) MMCs and hybrid dc circuit breakers (DCCBs).
