摘　　要：随着随州500kV编钟变电站的建成投运,随州电网结构将会有大规模调整,其中之一即是从孝感电网中解环。此时,广水电网中几座110kV变电站需要进行失压操作,这一操作将使得由这几座110kV变电站作电源的35kV变电站失去电压,三座光伏电站将脱网,还会造成包括一些重要用户在内的大规模停电。文章针对以上问题进行分析,并提出了相应解决措施。With the completion and operation of Suizhou 500kV bell substation,the structure of Suizhou power grid will be adjusted on a large scale,one of which is to remove the loop from Xiaogan power grid.At this time,several 110kV substations in Guangshui power grid need to operate under voltage loss.This operation will cause the 35kV substations powered by these 110kV substations to lose voltage,the three PV stations will be disconnected,and will result in largescale blackouts,including some important users.The article analyzed the above problems and puts forward corresponding solutions.
