摘　　要：风电汇集地区的自动电压控制(AVC)系统对优化汇集地区的电压运行水平有十分重要的作用,其控制策略处于核心地位。通过概括近年来我国风机脱网事故,指出研究风电汇集地区的AVC系统的重要性;介绍AVC系统发展概况与目前风电场无功电压控制策略的研究现状;详细阐述目前我国风电场所应用的AVC系统的控制策略,最后总结出目前风电汇集地区AVC系统所存在的问题和改进之处。The automatic voltage control （AVC） system of wind power centralized area is very important for optimi- zing voltage operation level, and its control strategy plays an important role. In this paper, firstly, it summarizes the large scale of wind turbines detaching from the system in recent years,pointing out the importance of the AVC system in wind power centralized area. Then it introduces the development of AVC system and the research on the control strategy of the AVC system in wind farms. Followed by the applications of AVC system control strategy in wind farm. Finally it summarizes current problems and improvements of the wind farm AVC system.
