电动汽车交流充电桩谐波分析及谐波抑制研究
Harmonic analysis of electric vehicle AC charging spot and research on harmonic restriction
摘要
Abstract
AC charging spot,a major energy supply facility for electric vehicles,uses on-mounted charger to power the battery of household electric cars.The harmonic pollution of electric vehicle chargers is increasing rapidly as the scale of electric vehicle charging stations enlarge.This paper builds a model of single-phase vehicular charger.Besides,it analyzes the harmonic characteristics in detail.The influence on grid harmonic by the changes in the number of charging stations is analyzed.In view of the harmonic problem of charging spot,the active power filter technology is applied to the AC charging spot.In the simulation model,based on the load characteristics of single-phase vehicular charger,the traditional PI control and repetitive control are combined,which can improve the quality of the grid side power and reduce the influence of harmonics on electric energy.关键词
