针对110 kV内桥接线智能变电站死区故障或主供线路侧开关异常时常规备用电源自动投入(简称备自投)装置动作逻辑的不足，提出了站域备自投装置基于过程层网络的应用方案。详细论述了站域备自投装置通过改进逻辑，统一控制高低压侧断路器来扩大备自投逻辑的动作范围，并可以实现电源切换时全站负荷零损失。

In view of the inadequacy of conventional automatic switchover device when the breaker is abnormal or failure occurs on bus at the internal bridge connection substation,the application of substation area automatic switchover device based on the process layer network is proposed.An elaboration is made of how the range of automatic switchover device is expanded by the improved logic of the substation area automatic switchover device and and how zero load loss is attained during switchover for the whole station by unified control of the high and low voltage side switches.
