| Abstract | ||||
| In the recent years the growing use of nonlinear loads, such as power converter , Uninterruptible Power Supply (UPS), and Adjustable Speed Drives (ASD) had been increased rapidly. All of these loads inject harmonic current into the power system. This paper presents a study and simulation of a three-phase Active Power Filter (APF) controlled by Fuzzy Logical Controller (FLC) to improve the Power Quality (PQ) of the distribution system by reducing the Total Harmonic Distortion (THD) and compensating the reactive power. The Synchronous Reference D-Q Frame (SRF) theory is used to generate the reference compensating currents for APF. In this paper APF controlled by FLC is developed to regulated the voltage of the DC capacitor. The main purpose of the proposed APF was tested using the MATLAB/SIMULINK toolbox and the results satisfy the harmonic limit specified by IEEE harmonic standard 519. The obtained simulation results are presents and compared with the conventional PI controller. The simulation results show that the proposed FLC has better performance over the PI controller especially when the load is varied | ||||
