摘要
介绍了串联型有源电力滤波器的基本工作原理,研究了基于三相瞬时无功功率理论的谐波电压检测方法,并分析了系统主要参数的选取方法,最后结合检测负载谐波电压控制方式用Matlab/Simulink搭建了系统的仿真模型.仿真结果验证了在合理的参数配置下,串联型有源电力滤波器可对电压型谐波能进行较好的补偿,使得电源电流的畸变减小.
This paper presents the basic operation principle and the harmonic voltage detecting method based on 3 phase instantaneous reactive power theory. The circuit parameter selection method is analyzed. Finally using the Matlab/Simulink software （mainly the toolbox PowerSystem Blockset）, a simulation system of series active power filter with the control scheme of detecting the load harmonic voltage method is built. In the end, a result is given to show that the series active power filter can compensate the voltage type harmonic source correctly and feasibly and reduce aberrance of current under proper parameter configuration.
