Power quality problems are of great concern due to the excess use of power electronic devices in power system. Voltage related power quality problems and its solution are discussed in this paper. Dynamic Voltage Restorer (DVR) is one of the custom power devices used to mitigate voltage related power quality issues such as voltage sag/swell, voltage distortions due to harmonics etc. Of these voltages sag is found to be the most common disturbance in the distribution systems. In this paper, a cost effective design of DVR for a three phase four wire distribution system is proposed.
