摘　　要：如何降低混合有源电力滤波器有缘部分电流容量,消除无源滤波器补偿无功及谐波时产生的谐振是混合有源电力滤波器的重要目标。为此,提出一种具有选择性谐波补偿的混合型有源电力滤波器(HAPF)。将有源滤波器与单调谐无源滤波器的电感并联组合,此拓扑结构显著降低了APF上的电流。并且采用具有选择性谐波补偿功能的比例谐振(PR)控制器,可选择地滤除含量较高的谐波。控制器在同步参考系下实现,相比PI控制使用谐振器数量减半,稳定性好,动态响应速度快。并且通过理论分析、仿真与实验验证了该混合滤波器结构和控制方法的可行性和有效性。To reduce the active part of the current capacity, and eliminate the resonance generated by the passive filterwhen compensating the reactive power and harmonic, a hybrid active power filter with a selective harmonic compensa-tion is proposed in this paper. The inductance of shunt active filter is combined with that of the single tuned passive fil-ters, which greatly reduces the current of active power filter. The adoption of selective harmonic compensation of propor-tion resonance（PR）controller can selectively filter the high haimonic. Implemented in the synchronous reference frame,and using only half the number of resonators compared with PI controller, the proposed controller has good stability andfast dynamic response. Theoretical analysis and simulation results show the feasibility and effectiveness of the hybrid fil-ter structure and control method.
