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。

关 键 词:自动电压控制  在线预警  静态电压稳定  区域电网

Abstract: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.
Keywords:automatic voltage control  on-line early warning  static voltage stability  regional power grid
