Abstract Research on insulation coordination is fundamental during the design of back-to-back flexible MMC-HVDC converter station. Based on the analysis of typical fault condition of MMC-HVDC converter stations, the typical configuration scheme and selection principle of arresters are carried out. Besides, according to Khwaja-Alwan converter station in Afghanistan, simulation and modeling via PSCAD is given, minimum requirements for the parameters of arresters under various fault conditions are proposed, also the whole scheme of arrester configuration and insulation coordination are put forward and verified.

Key words： modular multilevel converter (MMC) flexible HVDC converter station fault condition arrester configuration insulation coordination
