| Abstract: | The harmonic current detection has great significance before harmonic compensation in APF.This paper described ip,iq algorithm based on instantaneous reactive power theory and builtcd Simulink simulation module by Simulink on one matrix.The harmonic current detection algorithm simulation system was built.Different filtering result could be achieved by changing the cut-off frequency of second-order low-pass filter.Considering real-timing and accuracy in APF,the best cut-off frequency was selected by the filtered single-phase current waveform and the THD analysis.The simulation has a better reference to actual filter circuit. |
