Abstract: Compared with synchronous generators, modular multilevel converter-based high voltage direct current (MMC-HVdc) stations have unique fault behaviors, potentially impeding the correct operations of distance relays of lines connecting MMC-HVdc stations. To minimize the adverse effect… read more here.

DOI: 10.1109/jsyst.2022.3155881
Abstract: The peculiar fault current signatures of modular multilevel converter-based high voltage dc transmission (MMC-HVdc) system degenerate the operating performance of conventional current differential protection (CDP). CDP may incur low sensitivity or maloperations, especially when MMC-HVdc… read more here.
