摘　　要：为解决三相四线制不对称电网系统的谐波污染问题,通过对三相四桥臂有源电力滤波器(APF)的电路结构进行分析,并与三桥臂APF的电流跟踪控制方法进行对比,提出了一种改进型的三维空间矢量电流预测方法,实现了四桥臂APF对谐波电流的有效补偿。仿真实验的结果证明了该方法的正确性与有效性。In this paper,a control algorithm used in four-leg active power filter（APF） was presented to resolve the problem of pollution in unbalanced power system.In order to compensate the harmonic current in four-leg APF,according to the analysis of circuit of APF and the comparison from three-leg APF,a current tract control algorithm was proposed,based on the improved three dimensional space vector control method.The simulation results prove the validness and availability of this method.
