摘要
为解决谐波电流长延时问题,根据三相电路的瞬时无功功率理论推导,采用三相/两相坐标变换方法,实现了一种有源电力滤波器的谐波电流实时检测方法。计算结果表明,该方法可以准确,实时地检测出谐波电流。
In this paper, a method of harmonic current detection of active power filter based on the 3 - phase instantaneous reactive - power theory deduction is realized by making use of the 3 - phase/2 - phase coordinate transformation. The method is able to deal with the problem of long detected duration. It shows from the calculating results that the harmonic current can be detected accurately and rapidly.
