摘　　要：针对无源滤波器的缺陷,提出了一种低压电网无源滤波器改造方案。在已安装无源滤波器的基础上,将有源滤波器通过小电感与无源滤波器相连,设计了混合有源滤波器。阐述了有源滤波部分谐波检测与控制方案的选取、新增补偿容量与品质因数的确定。实验与仿真结果表明,该方案具有能抑制谐波放大现象和提高滤波效果的特点。Considering limitations of the passive power filter （PPF）, a reform method of PPF for low voltage power grid was presented. On the basis of installed PPF, connecting active power filter to PPF by small inductor, a hybrid active power filter was designed. The selection of harmonic inspection and control method for active filter and certainty of last added compensation capacity and quality factor were expounded. The experiment and simulation results show that the reform method can damp harmonic resonance and improve the filtering effect.
