A Generalized Compensation Strategy for Dynamic Voltage Restorer

Abstract:

Dynamic voltage restorer (DVR) is used to mitigate the impact of the voltage sags. At first the structure of DVR and three basic compensation methods are introduced. Considering the compensation performance and the injection capability of the DVR, a generalized compensation strategy based on pre-fault compensation, energy-saving compensation and progressive phase rotation method is proposed. With this compensation strategy, the active power injected by DVR can be minimized on the premise of the quality of compensation. Simulation results demonstrate the efficacy of the proposed compensation strategy.
