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。
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.
