Abstract: Power quality problems such as voltage sag which is to be generate effect on industrial distribution system. In this paper analyses the application of custom power devices using dynamic voltage restorer for mitigation of power quality problems voltage sag due to starting of three phase induction motor.contol strategies for DVR is based on dqo transformation feed forward control techniques. DVR to have less THD In distribution system. the propose control scheme simulation results carried out by MATLAB Simulink. The result shows that although period of voltage sag and rating of the load changes even then voltage sags are totally compensated.

Keywords: Voltage sags, power quality, dynamic voltage restorer, THD, custom power device.
