摘要
Abstract
To improve the low anti-disturbance capability and the inability of traditional proportional-integral modular multi-level converter(MMC)circulation suppressors to suppress harmonics above the second order,an improved quasi-PIR control strategy was designed through analysis of the mechanism and characteristics of circulation generation,and its implementation method was provided.A three-phase MMC simulation model was built in MATLAB/Simulink,and its reliability was analyzed by com-paring it with traditional PI circulation suppression strategies.The results show that the distortion rate of the output arm current is only 5%of the original value,and the suppression effect of the proposed strategy is improved by 78%.关键词
