Modelling of Dynamic Voltage Restorer for Mitigation of Voltage Sag and Swell Using Phase Locked Loop

Deepa Patil, Datta Chavan

Abstract: Voltage variations such as sag and swells in the distribution system effects sensitive loads. For protection of electric circuitry and sensitive equipments dynamic voltage restorers are implemented. Dynamic Voltage Restorer (DVR) is modelled using Matlab Simulation program and using basic circuit analysis in this paper. Control scheme applied for modelling is bases on phase locked loop. Performance of DVR is presented with the help of simulation results under sag and swell conditions.
