摘要
Abstract
Based on analysis of the dynamic process of the arm capacitors during start-up and DC fault of a MMC,an improved equiv-alent electro-magnetic simulation model of MMC is proposed in this paper,and according to the dynamic characteristics of the total ca-pacitor voltage of an arm,an averaged value model of MMC for its operating condition simulaton is proposed. Then detailed switc-hing,equivalent and averaged value electro-magnetic models of a 21-level MMC are built on PSCAD/EMTDC. By taking simulations during start-up,current step,AC fault and DC fault,the proposd equivalent model and average value model are proved to be suitable to replace the detailed simulation model of MMC in the converter-level study and power system level study with significantly increased simulation speed.关键词
