ABSTRACT:- In this paper the detail description of DVR, A DVR is a fast acting custom power device provides effective voltage control to the distribution feeder Every consumer expects a clean and uninterrupted power quality for their sensitive equipment. When there is flow of energy there will be fault and voltage sag, voltage swell, fluctuations and other problems which are most common in power system. Sudden change in loads, motor starting and faults in power system are main causes of voltage sag. Custom power devices are implemented to solar power quality problems. In custom power devices DVR is most effective. Simulation studies have been completed to attest the outcomes. DVR demonstrated and reenacted utilizing the MATLAB/ Simulink and simpower framework tool stash.
