Changing electric load and higher power transfer in a wide interconnected network lead stoserious, security lack in power system operations also if a sudden fault occurs there is a change in voltage profile which can lead to a sudden damage on load end. These voltage sags are compensated at generator side by various methods but at the load end there is a contingency. to avoid such sag at load side a mat lab model is proposed in which a transmission line is fed with two sources out of which one is a wind source and then is subjected to a 3 phase fault. the voltage sag which occurs is compensated in the other model at same instant when DVR Dynamic voltage restorer is programmed and is connected at the midpoint of grid. The results obtained shows that the voltage is compensated and profile is balanced, DVR uses the energy source in well timed manner and injects nessacary AC voltage to grid.
