摘要
为提高有源电力滤波器的容量并改善其补偿性能,从现有各种大容量有源电力滤波器的拓扑结构入手建立其数学模型,分析了各种结构的补偿原理并比较了它们的性能特点。研究结果表明:有源无源混合滤波器较适合于已安装了无源滤波器的场合,级联型多电平结构较适合于大容量的有源电力滤波器且该结构也是未来有源滤波技术发展的主要趋势。
Improving the capacity of APF has become a bottleneck to the development of harmonic mitigation technology. Therefore many scientists are searching for new power electronic circuit to improve the capacity of the APF and its compensating performance in current level of power electronic devise. In this paper, the author derivate the modeling of multifarious topologies, and has a full analysis to the structure and its compensation strategy and gives a comparison of all the topologies. At last put forward some opinion on the development of APF with large capacity： the hybrid filter is fit for those situation where the passive filter is existing; the CISDCS is predominant in the large capacity, and this topology is the future develooment trend nf APF.
