摘要
为了提高电网经济安全运行水平,依据混合式有源滤波器的原理,提出了基波串联谐振式混合有源滤波器.给出了混合有源滤波器的拓扑结构及主要特点,并基于瞬时无功理论的ip-iq电流检测算法搭建了实验模型.实验模型仿真结果表明,混合有源滤波器较好地发挥了无源滤波器和有源滤波器的优点,同时极大限度地减小了有源滤波器的容量,改善了无源滤波器的性能,对电网中的谐波电流分量具有良好的滤除特性.
For improving the safety of power grid,a novel hybrid active power filter with series resonance circuit tuned at fundamental frequency is proposed in this paper.The topology and the main characteristics of the filter are introduced,and the experimental model is built according to the ip-iq current detecting algorithm based on the instantaneous reactive theory.It is shown from the simulation results that hybrid active power filter combining the passive filter with active filter is recommended.The capacity of active power filter decreases to a great extent,meanwhile the filtering performance is good for the harmonic current of power system.
