摘　　要：通过对动态电压恢复器(DVR)的仿真模型分析,介绍了DVR的工作原理和相关的控制策略,并在PSB/Matlab下建立DVR和PWM控制器的模型,对电压跌落情况下的DVR电压补偿过程进行仿真。仿真结果验证了DVR的动态特性和对系统电压跌落的补偿效果。This paper dealt with the dynamic voltage restorer（DVR）,which is a series device that generates an AC voltage and injects it in series with the supply voltage to compensate the voltage sag.The compensation criteria and conclusions of the minimal energy output were sought on different voltage change levels,to provide accurate voltage and angle control for DVR,in order to reduce the loss and the cost.Simulation results were carried out by Matlab/Simulink,which are based on one phase compensation.It shows that the proposed voltage and angles can minimize the injection real power of DVR in different voltage situations.
