摘　　要：在变电站的运行过程中,母线的差动保护尤为重要,一次误动都会使一条母线失电,造成变电站停电,对电网稳定运行带来隐患。对某110 kV线路的一次故障使得一条母线停电的原因进行了分析,找出故障原因,并提出了相应的解决措施。In the operation process of the substation,the differential protection of the bus bars is particularly important.A misoperation will cause a bus to lose power,resulting in power failure of the substation,which brings hidden dangers to the stable operation of the power grid.The causes of a bus power failure caused by a fault of a 110 kV line are carefully analyzed,the action causes of the fault are found out,and the corresponding solutions are put forward.

关 键 词：母线 差动 稳定
