Studies of commutation failures in hybrid LCC/MMC HVDC systems [PDF]
Global Energy Interconnection, 2020 A hybrid of line commutated converters(LCCs) and modular multi-level converters(MMCs) can provide the advantages of both the technologies. However, the commutation failure still exists if the LCC operates as an inverter in a hybrid LCC/MMC system. In this paper, the system behavior during a commutation failure is investigated.
