摘要
介绍了ip-iq法和网侧电流法两种谐波电流检测方法的有源电力滤波器,对比传统有源电力滤波器ip-iq谐波检测方法的复杂性,提出了网侧电流检测法。此种方法不仅省去了传统有源滤波器谐波检测单元而且更为简单实用,并在Matlab/Simulink环境下,对两种谐波检测方式的有源电力滤波器进行了仿真分析比较,证明了网侧电流检测法的有效性和优越性。
The theory of i iqand gridside harmonics detection was proposed. Compared with the traditional complex active power filter based on theory ofip iq, the theory of gridside harmonics detection was introduced. This new theory discarded the traditional harmonics detective units to make it easier for practical. According to the compares of simulation results in Matlab/Simulink environment, the results strongly affirm the efficiency and advantage of gridside harmonics detection.
