A large capacity hybrid active power filter composed of passive filters,isolation transform, fundamental resonance and diode neutral point clamped three-level inverter was proposed to meet the requirements of harmonic elimination and reactive power composition in distribution network.Among them the passive filters maintain the network voltage while the fundamental resonance branch shunts the reactive current, which greatly reduces the rated current and voltage of the active filter.Active filter has structure of diode neutral point clamped three-level inverter. Its combined control strategies were adopted, and parameter change of fundamental resonance circuit was taken into account in this system.MATLAB simulations results prove the feasibility and validity of the novel hybrid active power filter.

针对中压配电网谐波治理问题,提出了一种大容量混合型有源滤波器。它由无源滤波器、基波谐振支路、隔离变压器及有源滤波器等组成。其中,无源滤波器承受大部分电网电压,基波谐振支路分流无功电流,它使有源滤波器的工作电压和电流大大降低;有源逆变器采用基于二极管中点箝位式(NPC)三电平结构,它使有源滤波器的工作电压大大提高。文中简述了该混合型滤波器的工作原理,分析了基波谐振支路在参数变化失谐时,对滤波性能的影响。仿真结果证实了新型混合有源滤波器的可行性和有效性。
