摘要
对并联型有源滤波器的谐波和无功电流检测方法进行了讨论,对目前常用的基于瞬时无功理论畸变电流检测算法的p-q法,ip-iq法进行了理论分析与仿真验证,对比了两种检测算法,仿真结果表明,p-q法,ip-iq法均可以有效检测出谐波,但是ip-iq法要优于p-q法。
The methods for detecting harmonics and reactive current of the shunt Active Passive Filter is discussed and analyzed. The p-q and ip-iq methods based on theory of instantaneous reactive power were simulated and compared with simulation tool box in MATLAB software.The results showed the p-qand ip-iq methods were very useful for detecting harmonics and reactive current,and the ip-iq method was more effective than the p-q method.
