摘　　要：电动汽车作为一种具有随机性的移动负荷,大规模的并入电网可能导致配网线路过载、线损增加、电压降低、谐波等电能质量问题。以某种型号电动汽车充电机构成的充电站为例,在MATLAB中搭建仿真模型,分析充电站在电网上产生谐波的特点。As a kind of random mobile load,the large-scale integration of electric vehicles into the power grid may lead to power quality problems such as overloading of distribution network lines,increased line loss,voltage drop and harmonic.Taking a charging station composed of a certain type of electric vehicle charger as an example,a simulation model is built in MATLAB to analyze the characteristics of harmonics generated by the charging station on the power grid.

关 键 词：电动汽车 电网 充电桩 谐波
