摘　　要：介绍了一种针对中等功率非线性设备网侧谐波补偿的分布式并联混合型有源电力滤波器,并对其中无源滤波器的优化设计问题进行了重点研究,提出了一种实用的无源滤波器优化设计方法;详细分析了无源滤波器参数对有源模块开关管耐压、滤波支路电流的影响并推导了时域解析表达式;基于此优化设计方法,针对整流性负载进行了滤波器参数设计,相比传统的经验设计方法,在相同有源容量情况下,采用新的优化方法设计无源参数,滤波器滤波效果明显改善。仿真及实验结果验证了优化设计方法的有效性。This paper presents a distributed shunt hybrid active power filter for medium-power nonlinear devices＇ net harmonic current compensation. Research on the optimization of passive power filter is made and a practical design method is proposed. The effects of passive filter parameters on the switch voltage pressure and current of compensation approach are analyzed and the time domain analytical expressions are got. Based on this optimization method, passive filter parameters are designed for rectifier load system. Compared to traditional empirical design method, new optimization method improves the effect of filter significantly. Simulation and experimental results demonstrate the effectiveness of this optimization method.
