| Abstract: | Aiming at the harmonic in three-phase three-wire active power filter(APF),we studied a harmonic current rapid detection algorithm based on instantaneous reactive power theory.Combining with a second-order Butterworth low-pass filter for suppressing the frequency aliasing phenomenon,we realized high precision harmonic detection for APF.The experiment results validated the correctness and robustness of the method.It can greatly improve the APF compensation performance. |
