A Detecting Approach of Harmonic and Reactive Currents Based on Transformation of dq Coordinates

介绍一种基于dq坐标变换的谐波和无功电流检测法,并对该方法进行了理论分析和仿真研究。仿真结果表明,这种检测方法无论电源畸变与否都可以准确检测出谐波和无功电流。

A harmonic and reactive currents detection approach based on transformation of dq coordinates is introduced in the article. This method is also analyzed from theory and made simulation. The simulation results verify that the approach can detect harmonic current and reactive current no matter whether the power source is distortion or not.
