摘　　要：针对三相四线制并联型有源电力滤波器,设计一种以基于瞬时功率理论p-q算法的指令电流计算和改进的三角波比较的电流控制技术为核心的控制方案,分析了基于该方案的补偿原理,给出推导过程,并在Matlab/Simulink环境下搭建APF模型并进行仿真验证。仿真结果表明,该有源电力滤波器补偿效果显著,降低电流畸变率,平衡三相负载,补偿电流跟随性能好。To the active power filter in three-phase four-wire system,a control scheme was designed with instruction current of p-q algorithm based on instantaneous power theory and improved current control strategy comparing the triangular wave,the principle of filtering and compensation based on the theory was analyzed,gave derivation and built APF model under Matlab/Simulink environment and simulation.Simulation results show that the effects of active power filter compensation is significant,reducing the current distortion rate,balancing three-phase load,creating a good performance of compensation current to follow.
