有源电力滤波器的动态无功补偿方法研究

Research on dynamic reactive power compensation methods of active power filters

为克服大量分布式电源、电动汽车并网时对电网带来的冲击,同时考虑到分布式电源及负载的双重随机动态变化特性,文章对现有无功补偿装置进行了分析,提出采用有源电力滤波器(Active Power Filter,APF)对配电网进行动态无功补偿,并在MATLAB-Simulink中搭建仿真模型。经验证,APF动态无功补偿能力较好。

To overcome the impact of large-scale distributed power generation and electric vehicles connected to grid,considering the dual random dynamic change characteristic of distributed power generation and loads,based on analysis of the existing reactive power compensation devices,active power filter(APF)is proposed for dynamic reactive power compensation in distribution networks.A simulation model is built in MATLAB-Simulink to verify the dynamic reactive power compensation capability of APF.
