Abstract
A fast and efficient solution to voltage sag/swell problem is Dynamic voltage restorer (DVR). DVR is a power electronic based device that provides three phase controllable voltage source whose voltage vector i. e. magnitude and angle is added to the source voltage during sag event, to restore the load voltage to pre-sag condition. The DVR is designed for protecting the whole plant with loads in the range of some MVA. The load voltage can be restored within few milliseconds using DVR. Several configurations and control methods are suggested for the DVR. In this paper, an overview of the DVR, its function, configuration, components, compensating strategies and control methods are viewed along with the device capabilities and limitations.
