摘　　要：动态电压恢复器(DynamicVoltageRestorer,DVR)是目前解决电压质量问题最有效的手段之一。综述了国内外DVR的研究现状,分析了DVR的基本工作原理和主电路结构。对DVR的各种检测方法和补偿策略进行了深入的分析比较,指出改进后的d,q检测法完全能满足DVR的检测需要,综合考虑电压和能量补偿能力的优化补偿策略更具有实用性。随着电力用户对动态电压质量要求的不断提高,DVR必将在配电系统中得到广泛的应用。Dynamic Voltage Restorer （DVR） is one of the most effective means to solve voltage sag problems at present.This paper summarizes the research status and development of dynamic voltage restorer at home and abroad, analyzes the fundamental compensation principle and configuration of the main circuit.Especially the detection methods and compensation strategies of DVR are researched in detail.A series studies and analysis show that an improved d,q detection method is more appropriate and an optimal compensation strategy with voltage and energy considered is more practical.The analysis results indicated that DVR will be used extensively in distribution systems.
