摘要：
The Modular Multilevel Converter (MMC) with DC fault current blocking capacity has broad application prospects in High Voltage Direct Current (HVDC) transmission applications. This paper proposes a novel Dual Reverse Blocking Sub-Module (DRBSM) based MMC with DC fault current blocking capability. Under the same output voltage level, the DRBSM based MMC has a strong DC fault current blocking capability and less power losses compared with existing topologies. Moreover, the DRBSM based MMC can adopt the simple control and modulation strategy of the HBSM based MMC directly. This paper also analyzes the DRBSM structure, operation principle and DC fault current blocking mechanism. Finally, the feasibility and validity of the topological structure is verified by PSCAD/EMTDC simulation. © 2019, Power System Protection and Control Press. All right reserved.
