Harmonic Distortion Reduction in Distribution Power Network Using High-capacity Hybrid Active Power Filter with Fuzzy PI Controller: Simulation and Experiment

Abstract

Harmonics are still one of the important indicators to evaluate power quality. Based on the theory of harmonics and solutions to improve harmonic distortion, the article has proposed a model to reduce harmonic distortion in the distribution power network using a hybrid active power filter with fuzzy PI controller. The model of simulation by Matlab software, the simulation data is based on the characteristics and parameters of the specific distribution power network in Nghi Loc District - Nghe An. The simulation results on harmonics are calculated and analyzed, and the total harmonic distortion (TDH) meets specified conditions by standards. In addition, based on the measurement of voltage and current harmonic at PCC, the article also proposed an experimental model of a filter to reduce the harmonic distortion in the power system.
