摘　　要：电压暂降问题是众多电能质量问题中需要重点解决的关键问题,特别是由于近年来大量新能源的接入,电力系统的电能质量问题变得尤为突出。为实现电压暂降综合治理,从电网侧、用户侧和电压暂降治理新技术3个方面综述了针对电力系统电压暂降的治理措施。首先分析了电网侧和用户侧目前电压暂降缓解措施及其效果,旨在实现“网-荷”协调配合下的电压暂降综合治理,为选择恰当电压暂降治理方案提供依据。其次阐述了目前电压暂降治理新技术的研究现状及发展趋势,为进一步研究新型电压暂降控制技术提供研究方向。电压暂降难以避免,多种方法综合控制才能实现最有效的治理。The solution to voltage sag problem takes special precedence among the variety of power quality problems,and the large-scale access of new energy in recent years markedly highlights the power quality problem of the power system.In order to realize the comprehensive control of voltage sag,this paper summarizes the control measures of voltage sag in power system from three aspects-grid side,user side and new control techniques.Firstly,current measures for mitigating voltage sag at the grid side and the user side and their effects are analyzed,aiming at implementing comprehensive treatment of voltage sag under the coordination of"grid-load",and providing a basis for selecting the appropriate treatment scheme of voltage sag.Secondly,the current research status and development trend of voltage sag control techniques are described,which provides research direction for further researches.
