摘　　要：随着工业自动化程度的日益提高,电力用户对电能质量问题也越来越敏感,其中电压暂降、跌落已经成为影响电力负荷安全运行最突出的问题。动态电压恢复器(DVR)被认为是目前解决电压跌落问题最经济、有效的用户电力装置。在对电压跌落问题和治理措施进行阐述的基础之上,对一种新型的低压动态电压恢复期的性能进行了详细分析,并对用户使用选择低压动态电压恢复器给出了相关建议。With development of industry automation,the power customer is becoming more and more sensitive with power quality,with the focus on voltage sag.The dynamic voltage restorer（DVR） is considered as an effective and economic voltage sag solution.The problem of voltage sag and related countermeasures were illustrated,and based on that a new kind of low voltage DVR was proposed and recommended.Suggestions on low voltage DVR selection were also put forward for users.
