摘要
Abstract
In this paper,the working mechanism of modular multilevel converter(MMC)is briefly introduced at first. Second,to deal with the problem of circulating current suppression and capacitor voltage balance of MMC,a new meth-od is proposed to suppress the circulating current and achieve the capacitor voltage balance based on CPSM. Finally , considering the AC asymmetrical fault of MMC-HVDC,a sub-sequence current inner loop controller and an outer loop power controller are designed based on deadbeat control. Using PSCAD/EMTDC,the simulation result verifies the cor-rectness and effectiveness of the proposed control strategy.关键词
