#### Abstract

The production of electric energy is basic pillar for normal functioning of every modern society. But in present day’s power distribution system is suffering from severe power quality problems. To reduce such problems we are using advanced technologies in power electronic devices (semi conductor devices). However these power equipments which include Adjustable Speed motor Drives (ASDs), electronic power supplies, direct current (DC) motor drives, battery chargers, electronic ballasts are responsible for the rise in related PQ problems. These non-linear loads are constructed by nonlinear devices. But these non-linear loads appear to be prime sources of harmonic distortion in power distribution system. Harmonic currents produced by non-linear loads are injected back into power distribution systems through the Point of Common Coupling (PCC). These harmonic currents can interact adversely with a wide range of power system equipment, most notably capacitors, transformers and motors causing additional losses, overheating and overloading. And also it can decrease the power quality in power distribution system. Traditionally, current harmonics caused by non-linear loads have been dealt with using passive filters consisting of capacitors, inductors and damping resistors. This paper mainly concentrates on proposing a new PWM current controlled Shunt Active Power Filter, to propose a simple current reference estimation method for the proposed topology, to design a Takagi-Sugeno (TS) type Fuzzy Logic Controller (FLC) to a three phase Shunt Active Power Filter which can decrease the harmonics so that the quality of power increases in power distribution systems. The first objective is achieved by designing a PWM current controlled Voltage Source Inverter which acts as a Shunt Active Filter for a three phase three wire system. For the second objective, this paper proposes the application of the extension instantaneous reactive-power (p-q) theorem to estimate the compensation current reference. The third objective is achieved by designing a Takagi-Sugeno (TS) Fuzzy Logic Controller with seven fuzzy sets for each input and output, triangular membership functions for simplicity, fuzzification using continuous universe of discourse and defuzzification using the centroid method. This paper will give the MATLAB/SIMULINK circuits of above proposals which interm gives the solutions to improve the power quality in power distribution systems. *Copyright © 2013 Praise Worthy Prize - All rights reserved.*
