Aiming at the problems of large workload, low efficiency and incomplete function coverage in the maintenance process of VSC-HVDC project, this paper studies the SM detection technology of MMC. Firstly, it analyzes the background and significance of this research, then based on the elaboration of the working principle of SM, a SM function detection method is proposed. This method can not only realize the automatic detection of multiple mmc-sms, but also cover all the power components except the thyristor of SM, which greatly simplifies and improves the detection steps and efficiency. The feasibility and effectiveness of the method are verified by simulation analysis.
