The growth of power electronic technology in the field of electric power sector has caused a greaterawareness on the power quality of distribution systems. With the re-structuring of power systems and with shifting trendtowards distributed and dispersed generation, the issue of power quality is going to take newer dimensions. The presentresearch is to identify the prominent concerns in this area and hence the measures that can enhance the quality of power.The research work is going to be investigates the problems of voltage sag, swell and its severe impact on nonlinearloads, sensitive loads. Protection of the sensitive unbalanced nonlinear loads from sag/swell, distortion, and unbalancein supply voltage is achieved economically using the dynamic voltage restorer (DVR).DVR is installed between supplyand load which will inject voltage and active power to the distribution system during balanced/unbalanced voltage sagand swell disturbances. The control technique used to operate the DVR is SRF Theory with Proportional Integral (PI)controller. The performance of DVR based Synchronous reference frame theory (SRF) for the mitigation of voltage sag,swell for balanced and unbalanced voltages is going to be tested and Simulation results are going to be carried out byPROTEUS with its Simu-link to analyze the proposed method .
