Sarang V. Bhonde, Ravindra S. Pote

Abstract: Voltage sag & swell creates useless dispute at the customer side as well as utility side. In this paper, dynamic voltage restorer device based on voltage source converter topology is used to compensate voltage sag & swell. Dynamic Voltage Restorer (DVR) is a power electronic device that is utilized to improve voltage stability i. e. To reduce the power quality problems in electrical power system network. Usually DVR is installed between load feeder and source in the distribution system. In this paper approach to compensate voltage sag & swell by using dynamic voltage restorer base on sin template generation is discussed. Simulation is done in MATLAB software and results are obtained.
