摘　　要：针对现行的常规备自投控制策略的不足,开发了基于EMS中高级应用软件系统的广域备自投控制决策方法,对全网所有变电站备自投的负荷联切定值进行实时整定计算。新研制的厂站端备自投装置接收来自远方主站端调度中心的控制定值,根据动作条件和控制定值自动切除相应的负荷馈线,并且通过软/硬压板灵活实现新型的"远方"和传统的"就地"备自投功能。经过严格现场测试和长时间的试运行,结果表明该新型广域备自投控制系统充分考虑了整个电网的安全稳定性约束,有效地提高了地区电网运行的安全性和供电可靠性。Aiming at the deficiencies of conventional automatic bus transfer control strategy,the wide-area automatic bus transfer control system of regional power grid is developed based on the advanced application software of EMS.Its control and decision-making strategy calculates the real-time load shedding settings for all substation automatic bus transfer devices of power grid.The developed automatic bus transfer device receives the control settings from the master station in dispatch center and disconnects the relevant feeder automatically according to the action conditions and control settings.It realizes the ＂remote＂ or ＂local＂ automatic bus transfer functions flexibly by soft / hard platen.Field test and trial operation show that the wide-area automatic bus transfer control system considers the security and stability constraints of the whole power grid,efficiently improving the security and reliability of regional power network.
