摘要: 提出了一种三电平并联型有源电力滤波器双闭环控制系统的设计方案。该系统采用ip-iq法提取谐波，利用瞬时无功功率理论检测三相电压与负载电流，用以计算补偿电流；其电压外环采用模糊PI控制器控制，电流内环采用内模控制器控制，并由三电平SVPWM调制器输出补偿电流。仿真实验结果验证了该系统具有良好的谐波补偿效果。

Abstract: The paper put forward a design scheme of control system with double closed loops of three-level SAPF. The system uses ip-iq method to extract harmonics and uses instantaneous reactive power theory to detect three-phase voltage and load current, so as to calculate compensation current. The voltage loop is controlled by fuzzy PI controller and current loop is controlled by internal model controller. Meanwhile, the system adopts three-level SVPWM modulator to output compensation current. The simulation experiment result showed that the system has good harmonic compensation effect.
