Dynamic Voltage Restorer against Voltage Sag

H.P. Tiwari and Sunil Kumar Gupta

Abstract—A dynamic voltage restorer (DVR) is a custom power device used to correct the voltage sag by injecting voltage as well power into the system. The mitigation capability of these devices is mainly influence by the maximum load; power factor and maximum voltage dip to be compensated. Voltage Dips on a feeder is an important task for DVR system operation and appropriate desired voltage sag compensation. This paper is intended to assimilate the amount of DC energy storage depends on voltage dip. It is available in a convenient manner for DVR power circuit.

Index Terms—DC Energy Storage, Dynamic Voltage Restorer, Power Quality, Voltage Sag.
