| 摘 要： | 简要分析了动态电压恢复器（DVR）的开环控制策略，指出了该控制策略对系统的不利影响。提出了一种基于干扰电压前馈的新的控制策略，增加了系统的稳定裕度，提高了系统的动态响应速度。并通过仿真验证了改进控制策略下DVR补偿的有效性。

| Abstract: | The open-loop control strategy of dynamic restorer was briefly analyzed,and its bad effect on the system was pointed out.A new control strategy based on interference voltage feed-forward adjustment was proposed.The new control strategy not only improved steady margin,but also sped up system dynamic response.The better performance of improved control strategy was then validated by simulation. |
