Abstract

Full-Bridge Modular Multilevel Converter (FBMMC) has strong ability to ride through serious DC faults, thus it is very suitable for multi-terminal flexible HVDC applications. However, no references have reported the locating and isolating of DC faults and corresponding DC faults ride-through capability evaluation index. This paper introduces the topology mechanism of FBMMC and its loss reduction operation mode, theoretically certifies that the universal decoupled control strategy of Voltage Source Converter (VSC) and the similar modulation strategies of Half-Bridge MMC (HBMMC) can be applied to FBMMC for constructing complete closed-loop control system. On the basis of the existing DC faults locating and isolating schemes of 2-level VSC based Multi-Terminal HVDC (VSC-MTDC) system and the particularity of FBMMC, this paper proposes the DC faults wire selection “handshaking” method of the FBMMC-MTDC system, and proposes the DC Fault Ride-Through Capability Index (DFRTI) for evaluating the DC faults suppressing capability of the VSC-MTDC systems, including FBMMC-MTDC. Simulations of FBMMC-MTDC in PSCAD/EMTDC validate the correctness and effectiveness of the proposed control strategy and evaluation index.
