Abstract
Modular multi-level converter has become one of the most prospective converter technologies in HVDC transmission. According to the topological structure and mathematical model of MMC, this paper proposes a multi-point DC voltage control strategy based on voltage margin control, and designs the corresponding controller. On this basis, the influence of DC single pole ground fault on the system is analyzed, and the relevant protection strategy is proposed. Finally, the PSCAD/EMTDC is utilized to simulate the single pole ground fault and implement protection strategy. The simulation results indicate that the system can quickly recover after system fault and improve the system stability, the effectiveness of fault protection is proved.
