| Abstract: | Dynamic voltage restorer is considered to be one of the effective means to solve power quality problems such as voltage sag.DVR control strategies include feedforward control,compensation voltage feedback control and composite control strategy.The basic structure and working principle of the DVR on the voltage drop detection methods are introduced,the dynamic voltage restorer (DVR) control strategy is analysed,and the advantages and disadvantages of the three control strategies are pointed out.A DVR mathematical model is established and simulation verifies the feasibility and effectiveness of the DVR. |
