摘要
动态电压恢复器DVR(Dynamic Voltage Restorer)串联于电网络,用来保护敏感负荷免受电压波动尤其是电压凹陷的影响。该文讨论了动态电压恢复器实时补偿的检测原理及其特点,并结合负荷特性进行了综合比较。
A Dynamic Voltage Restorer (DVR) is connected in series with the network.The main function of a DVR is the protection of sensitive loads from influence of the voltage fluctuation, especially voltage sag.This paper deals with the main identification methods, combines the characteristics of the loads to have a general compare.
