摘　　要：针对电动汽车充电站连接的三相四线制配电系统电能质量问题,采用应用于三相四线制系统中的配电网静止同步补偿器(DSTATCOM),对电动汽车直流充电站进行无功补偿及谐波治理。DSTATCOM主电路采用中点引出式三桥臂两电平逆变器,在建立其数学模型基础上,提出一种新型三维空间矢量调制(3-D SVM)控制策略,节约计算时间。搭建实验样机,实验结果表明中点引出式三桥臂DSTATCOM可以对无功进行补偿,同时还可以有效地抑制谐波电流和中线电流。For electric vehicle charging station connected three phase four wire system of power distribution system power quality problems, the application in three phase four wire system of distribution static synchronous compensator （ DSTATCOM）, electric vehicle charging stations for reactive power compensation and harmonic management. DSTATCOM main circuit adopts the midpoint raises three two level inverter bridge arm, on the basis of its mathematical model is set up, put forward a new type of three-dimensional space vector modulation（ 3- d SVM）control strategy, save computation time. Structures, experimental prototype, the experimental results show that neutral DSTATCOM can lead to three bridge arms for reactive power compensation, at the same time also can effectively suppress harmonic current and line current.
