摘　　要：非线性负载大规模出现在电力行业中,使得电网中产生大量的谐波污染问题,有源电力滤波器能够有效抑制谐波和补偿无功。阐述了APF的基本原理、主电路拓扑结构。建立了三相三线并联型有源电力滤波器在三相静止和两相旋转坐标系下的数学模型,电流环采用PI控制,低通滤波器环节采用移动平均滤波器进行控制,实现对电网电压的准确跟踪。利用MATLAB/Simulink平台进行仿真分析,实验表明:谐波含量从30.74%降到了14.17%,APF能够进行谐波抑制和补偿。The large-scale non-linear load appears in the power industry,causing a large number of harmonic pollution problems in the power grid.The active power filter can effectively suppress harmonics and compensate reactive power.This article describes the basic principles of APF,the main circuit topology.A mathematical model for the three-phase three-wire shunt active power filter in three-phase stationary and two-phase rotating coordinate systems was established.The current loop was controlled by PI and the lowpass filter was controlled by a moving average filter to achieve grid voltage.Accurate tracking was also realized.Using MATLAB/Simulink platform for simulation analysis,the experiment shows that the harmonic content is reduced from 30.74%to 14.17%,and APF can perform harmonic suppression and compensation.
