Abstract
This paper aims to address the problem of return power existing in grid-connected interface system of the wind power system caused by replacing the power electronic transformer into conventional transformer.The study involves optimizing the control measures of the power electronic transformer to im-prove the traditional double phase-shift control method;changing the shifting ratios of D1,D2 on the basis of traditional double phase-shift contrl,and achieving the best combination,which can reduce the return power in system and improve the efficiency of the system;and modeling and simulating the system of im-proved control measure in Matlab.The results show that the minimum value of the output power is about-5 kW before improvement,and the minimum value of the output power is about-1.5 kW after apply-ing the improved phase-shift control method to PMSG-PET system.The effective reduction of the system return power proves the effectiveness of the improved phase-shift control measures.关键词
