Performance of Powersystem to Enhance Power Quality using Fuzzy Logic Controller Based DVR

This paper accord the Power Quality interpretation to make apparent for electricity consumers been made better power quality with application of DVR.Despite of advantages of DVR, it focuses full extent of the relatedness surrounded by loads, various power networks. DVR is most accepted power device which could be used for better solution for the disturbances of voltages in distribution systems for sensitive loads. For efficiency considerations, the DVR mostly hinge on an act of presenting the control modus, and can be harnessed to switching the inverters. Reliability of hysteresis voltage control with ease in operation under variable switching frequency can be trustworthy for a DVR can introduced and the proposed methods achieves good compensation of voltages under disturbances and can be seen by the simulation by using fuzzy logic controller.
