摘　　要：研究了一种新型双谐振注入式混合型有源电力滤波器(hybrid active power filter,HAPF),通过添加基波串联谐振支路与有源部分并联以减小它的基波分压,通过添加基波并联谐振支路构成注入通道,增强谐波电流注入能力的同时避免无功过补,并能够通过系统中的无源滤波器组来补偿大容量无功功率。针对某110 kV变电站谐波抑制和无功补偿的工程需求,详细介绍了兼具大容量无功静补能力的双谐振注入式HAPF应用方案的设计、设备参数、装置主要组成部分以及仿真、实验情况等,并给出了装置投运后的预期降损节能效益,仿真和实验结果证明了所提双谐振注入式HAPF方案的可行性和有效性。A new double resonance injection type of hybrid active power filter （HAPF） is researched. By means of adding a power frequency series resonance branch connected to active part in parallel, the divided fundamental voltage of the active part is reduced; by means of adding fundamental parallel resonance branch, an injection channel is constructed, so the overcompensation of reactive power can be avoided while the injection ability of harmonic currents is enhanced, thus large capacity of reactive power can be compensated through passive filter groups in the system. According to the requirement of a certain 110kV substation to harmonic suppression and reactive power compensation, the design of the applied scheme of HAPF, its parameters and main components as well as the simulation and experiments of the applied scheme are presented in detail, and the energy-saving and loss reduction benefits brought about by the application of the proposed HAPF are given. The feasibility and effectiveness of the proposed double resonance injection type of HAPF are verified by results of simulation and experiments.
