The problems faced by a power system are sudden variations in voltage, transient currents, short circuits e. t. c. among all these sudden variations in voltage is the major and frequent problem which occurs mainly in distribution networks. This problem results in the damage of sensitive load. This problem can be solved by means of using capacitor banks, but this doesn�t provide an accurate solution. Hence this paper provides an effective solution to this problem by using the FACT devices which are efficient. This paper also provides the modeling and simulation results by which the working and performance of Dynamic Voltage Restorer (DVR) in the conditions of both balanced and unbalanced voltage sags and swells can know. Hence the voltage Quality in distribution networks can be improved.
