大功率低成本新型混合型有源滤波器的电流检测方法
Detecting current method of new high capacity hybrid active power filter with low cost
摘要
Abstract
This paper proposed a new high capacity hybrid active power filter with 3-phase 4-switch inverter, which could be applied in high grid system. Analyzed the topology structure of the given system and the inverter. Proposed an improved detec-ting harmonic current method based on single current detection, which just decreased computing time greatly. Presented a de-tecting DC link current method based on energy balance. The system detected two-phase currents and controlled 4 switches. Simulated the new hybrid APF based on the inverter of 3-phase 4-switch. The results show that the filtering equipment based on the inverter of 3-phase 4-switch can suppress harmonics and compensate reactive power well. The DC link voltage is kept stable and balance. The cost and loss of the new filtering equipment are decreased greatly.关键词
