摘　　要：分析了三相并联型有源电力滤波器的系统结构和工作原理,介绍了基于三相瞬时无功功率理论的指令电流计算方法和主电路的控制策略,在此基础上建立了有源电力滤波器的仿真模型,并在MatLAB/Simulink平台上对该模型进行了仿真。仿真结果表明谐波计算方法正确,主电路控制策略合理,所设计的有源电力滤波器能够有效地抑制谐波电流,显著提高了电能质量。The system structure and the operating principle of a three-phase shunt active power are analyzed in this paper. And the algorithm of computing harmonic current based on three-phase instantaneous reactive power theory and hysteresis current tracking control strategy is introduced. A model of APF is established and simulation has been came out in MatLAB/Simulink. The result of simulation shows that method of computing harmonic current and the control strategy are correct. APF can compensate harmonic current and improve the power quality effectively.
