摘　　要：发展电动汽车必须建设大规模充电站,进而电网势必会注入充电站工作时产生的大量谐波。该谐波的一致措施一般有主动型谐波抑制和被动性谐波抑制两种,针对电动汽车充电站产生谐波的被动抑制措施中,比较了无源滤波器和有源滤波器的优缺点,在对电动汽车充电站的谐波分析的基础上,本文提出了一种无源滤波器谐波抑制方法,用以谐波治理的模型在Matlab/Simulink平台上进行对比分析,结果表明无源滤波器对谐波电流的畸变能有效抑制,该无源滤波器更适合在电动汽车充电站中推广应用。The development of electric vehicles requires large-scale construction of charging stations,and a large number of harmonic current generated in the charging station will be inject into the grid.There are generally two types of harmonic suppression methods of charging stations,such as active harmonic suppression and passive harmonic suppression.Aiming to the passive harmonic suppression in the electric vehicle charging station,the advantages and disadvantages of the passive power filter and active power filter are compared.On the basis of the harmonic analysis of the electric vehicle charging station,the paper proposes a harmonic suppression method of a passive power filter.The harmonious simulation model is established by the Matlab/Simulink platform.The simulation result shows that the passive power filter can effectively reduce the total resisure of the harmonic current generated by the charging station.
