摘要：
At present, the research on the principle and settings of DC pole protection for MMC-HVDC(Modular Multilevel Converter based High Voltage Direct Current) is concerned about the normal operating conditions of the system, there is little adaptability analysis of DC pole protection during start-up process. The dynamic start-up process of MMC-HVDC is described theoretically, and the characteristics of DC pole-to-pole short circuit fault and monopolar grounding fault are analyzed in detail. The difference of related quantities of typical DC pole protection between fault occurred during start-up process and normal operating stage is analyzed, and the adaptability of the typical protection to fault occurred during start-up process is also studied. Based on detailed electromagnetic transient model of MMC-HVDC system, the DC pole-to-pole short circuit fault and monopolar grounding fault occurred during both start-up process and normal operating stage are simulated, which verifies the analysis on fault characteristics during start-up process and the adaptability of typical protection to start-up process. New suggestions are put forward for the protection setting calculation. © 2019, Electric Power Automation Equipment Press. All right reserved.
