摘　　要：设计并实现了区域电网自动电压控制(AVC)系统。提出了区域电网AVC模式,包含对直控电网的闭环控制和对各下级电网的协调控制2部分;在主站系统中实现了对500 kV变电站内部的电容、电抗器、有载调压分接头(离散控制设备)和调相机(连续调节设备)的综合协调和闭环控制;通过约束条件的实时修改实现了电厂与变电站的协调控制;实现了在线静态电压稳定预警与AVC功能的协调;实现了三维可视化功能。该系统已在华北电网实际运行。An automatic voltage control （AVC） system for a large regional power grid is designed and implemented in North China Power Grid. The following new works are reported in this paper： an automatic voltage control mode for regional power grid based on a direct closed-loop control for its own area coordinated with lower-level control centers; an automatic control for 500 kV substation by coordinating with capacitors, reactors, OLTCs and synchronous condensers; a coordinated-control between power plants and substations by online modifying their own constraints; coordination of AVC system with the online security early warning system to ensure static voltage stability; 3-D visualization. This AVC system has been put into real time operation and an excellent performance of the AVC has been observed.
