电动汽车充电站并联APF谐波放大效应研究
Research on harmonic amplification effect of shunt APF in electric vehicle charging station
电动汽车充电过程中会产生谐波,常采用并联有源电力滤波器(active power filter,APF)的方式来补偿谐波。但是并联APF在补偿谐波时会产生谐波放大效应。本文通过采用等效电路分析的方法,提出一种量化谐波放大程度方法,根据此方法来改进谐波补偿电路的拓扑结构,以消除谐波放大效应,最后在MATLAB仿真软件上验证此方法的正确性。本文的研究有利于提高电动汽车充电站中并联APF的设计和利用。
英文摘要:
Electric vehicle charging process will produce harmonics,we often use shunt active power filter(APF) to compensate harmonics. However, shunt APF will generate harmonic amplification effect during compensating harmonics. This paper propose a method to quantify the degree of harmonic amplification by using equivalent circuit analysis, according to this method to improve the topology of harmonic compensation circuit, and the harmonic amplification effect is eliminated,finally, the correctness of the method is verified by MATLAB simulation software. This study will help to improve the design and utilization of shunt APF’s in electric vehicle charging stations.
