The present power system is a complex network and specially the power distribution network is very intricate. Voltage sag is the most severe problem among all power quality issues. Voltage sag can cause critical power interruption in the distribution network. Generally, voltage sag occurs with the fault in the power system. In this paper, the working of dynamic voltage restorer (DVR) for the compensation of source voltage sag is presented. Here, a voltage sag in the source voltage due to three phase fault has been compensated by the photo voltaic (PV) voltage through voltage source inverter (VSI) with a DVR control scheme. The pre-sag open loop feed forward control scheme has been used for this purpose.
