摘要
分析了并联有源滤波器的基本工作原理,提出了一种谐波和无功电流检测的新算法,对此作了详细的理论分析。此检测算法不需要锁相环,能准确检测出负载电流中谐波及无功分量。对这种检测算法用 MATLAB 进行了仿真,并在以 TMS320F2407 DSP 为控制核心的实验装置中对这种检测算法作了具体实现,仿真结果和实验结果均证实了这种检测方法的可行性。
A new algorithm of detecting harmonic and reactive current in active power filter is discussed.In addition,the simulation result base on MATLAB and the experiment result base on TMS320F2407 are given.The results show that the proposed algorithm is valid,and the harmonic and reactive current can be detected accurately.
