摘　　要：牵引供电系统中大量非线性元件的使用,在系统中产生了大量的谐波与无功电流。采用有功电流分离法,分离出牵引变压器副边的基波有功电流,从而得到补偿电流,利用有源电力滤波器对其进行补偿,通过MATLAB仿真,说明了补偿方法的可行性。A large number of harmonics and reactive current are generated because of the use of nonlinear elements in the traction power supply system. In this paper, the active current separation is used to separate the active current of the secondary side of the transformer and get the compensation current.The feasibility of the compensation method of using active power filter （APF） for compensation is described and verified by MATLAB simulation.
