| Abstract: | 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. |
