Enhancement of Voltage Quality in Power System through Series Compensation using DVR

Voltage sag & swell creates useless dispute at the customer side as well as utility side. This paper present, dynamic voltage restorer device is custom power device is used to mitigate voltage sag & voltage swell. Dynamic Voltage Restorer (DVR) is a custom power device that is utilized to compensate the unbalance voltage i.e. to compensate the power quality problems in electrical power system. Usually DVR is installed between load feeder and point of common coupling in the network. In this paper approach to mitigate voltage sagas well as voltage swell by using dynamic voltage restorer base on sine vector template generation is discussed. Simulation is done with the use of MATLAB software and results are obtained.
