摘　　要：采用动态电压恢复器(dynamic voltage restorer,DVR)可有效补偿电压暂降。为了更好地衔接动态电压恢复器的检测算法和控制策略,避免因非故障引起的供电电压波动而造成的DVR装置的频繁启动,提高DVR装置工作的可靠性和实时性,将启动算法分为检测算法和启动判据两部分,提出了一种较适合工程应用DVR装置的启动判据。Dynamic voltage restorer （DVR） can effectively compensate temporary voltage drop. To better link DVR detection algorithms and control strategies, avoid frequent DVR switching due to non-fault-caused voltage fluctuations, and increase DVR reliability and instantaneousness, a DVR switching criterion suitable for engineering applications is presented by dividing switching algorithm into 2 parts, namely, detection algorithm and switching criterion.
