摘要
Abstract
Under the influence of energy,environment and other factors,the development of the electric vehicle industry has attracted much attention,while the harmonics generated by the large-scale access of electric vehicles will have inevitable impact on the power grid. Firstly,the simulation model of the single charger as well as the charging station were established. Secondly,the charging power curve was equivalent to a constant resistance and a time-varying resistance and the harmonic characteristics of a single charger and multiple chargers were studied in the constant power mode and the actual charging power mode,respectively. Then,the harmonics of different chargers were analyzed,and the fundamental and harmonic currents on both sides of the distribution transformer were compared. Finally,the characteristics of harmonics of different starting charging states were briefly analyzed.关键词
