A Dynamic Voltage Restorer (DVR) For Protecting Hybrid Grids | Asian Basic and Applied Research Journal

Dynamic Voltage Restorer (DVR), for some important reasons, is utilized in Power Distribution for protecting loads especially critical loads against some power quality issues like sag, swell, harmonics and faults. Fast transient response for compensating voltage quality is an unavoidable factor. Different control topologies have been applied to this device. In this project, a DVR is deployed to preserve a critical load which is connected in parallel with grid and A wind turbine. Several situations of power quality issues have been considered. The simulation results of a proposed system which has been implemented in MATLAB/Simulink show how DVR is effective for protecting loads.
