摘　　要：针对电动车充电站大面积投运造成电网电能质量问题,本文建立三相四线制系统充电站等效模型,利用MATLAB仿真软件分析了其谐波特点。应用有源电力滤波器(APF),对电动汽车充电站进行无功补偿及谐波治理。其主电路采用中点引出式三桥臂三电平逆变器,在建立其数学模型基础上,采用一种改进三维空间矢量调制(3-D SVM)控制策略,提高了系统响应速度。通过搭建实验样机,实验结果表明APF可以提高电网侧电能质量,同时还能抑制零线电流。For electric vehicle charging station operation of large area power grid power quality problem,this paper establish charging station equivalent model of three phase four wire system using MATLAB simulation software analyzes the harmonic characteristics. Application of three-phase four-wire active power filter（APF）,its main circuit USES the midpoint raises three three level inverter bridge arm,on the basis of its mathematical model is set up,using an improved three dimensional space vector modulation（3-d SVM）control strategy,improve the system response speed. Through constructing the experimental prototype,the experiment results show that the APF can improve the quality of grid side power,at the same time also can inhibit the line current.
