摘　　要：为了实现并联混合型有源电力滤波器(SHAPF)高补偿性能的要求,提出一种SHAPF电流双闭环控制策略。利用基波电流环为谐波电流环控制器提供阻尼项,实现有源阻尼的同时减少一组传感器,降低系统复杂度。分析了SHAPF的滤波特性,并给出了SHAPF系统配置的参数设计方法。分析了电流双闭环控制器在离散系统中的稳定性条件,并给出了控制器参数设计方法。搭建了SHAPF的仿真模型与实验样机。结果表明SHAPF具备良好的谐波补偿性能,验证了电流双闭环控制策略及参数设计的合理性。In order to achieve the requirement of high compensation performance of shunt hybrid active power filter(SHAPF),a SHAPF current dual closed-loop control strategy is proposed.The fundamental current loop is used to provide the damping term for the harmonic current loop controller to achieve active damping and reduce the complexity of the system by reducing a set of sensors.The filtering characteristics of the SHAPF are analyzed and the parameter design method of the SHAPF system configuration is given.The stability conditions of the current dual closedloop controller in the discrete system are analyzed and the controller parameter design method is given.The simulation model and the experimental prototype of SHAPF are built.The results show that the SHAPF has good harmonic compensation performance,and the rationality of the current dual closed-loop control strategy and the parameter design is verified.
