摘　　要：为有效地满足无功补偿和谐波抑制的要求,改善电网电能质量,降低混合有源滤波器装置开发成本,提出一种新型并联混合型有源电力滤波器拓扑结构,通过加入基波并联谐振电路,调谐于工频,使APF不再承受基波电压,从而减小APF(active power filter)容量,并对其工作原理进行了详细的分析。采用电力系统暂态仿真软件PSCAD/EMTDC进行仿真实验,结果表明新型拓扑结构比传统结构有更好的滤波性能,证明了该设计方案的有效性和正确性。In order to satisfy the requirements of reactive compensation and harmonic suppression, improve the power quality and reduce the developing cost of hybrid active power filter, a new topology of shunt hybrid active power filter is proposed. In the new topology, a base resonance circuit is introduced to reduce the capacity of APF. The working principle of the new topology is described. Simulation experiments are done with the software PSCAD/EMTDC,and the results show that the new topology has better filtering performance than the traditional one. The results also verify the effectiveness and validity of the new topology.
