摘　　要：备自投装置是保障电力系统连续可靠供电的重要设备。文章介绍了一起110 kV智能变电站中110 kV母线失压开关跳开后,由于网络报文丢包而导致备自投装置异常动作的事件,并针对这种现象提出相应的改进措施,从而保障二次装置的安全稳定运行。The automatic standby switching device is important to ensure the continuous and reliable power supply in power system. This paper introduces an abnormal action of the automatic standby switching device caused by the 110 kV busbar voltage loss in a 110 kV smart substation, which is caused by network packet loss after switching off. It then puts forward corresponding improvement measures, so that the safe and stable operation of the secondary device is ensured.
