摘要
对110 kV内桥接线变电站的备自投装置展开了研究,论述了备自投装置的基本要求和逻辑原理。针对变电站轻载状态下备自投装置易误动作的问题,结合两起相关案例,提出了完善电压回路设计和增加额外启动条件两个改进方向,并提出了相应的改进方案。
This article conducts research on the backup power automatic switching device of 110 kV internal bridge connection substation,and discusses its basic requirements and logical principles.In response to the problem of mistaken actuation of backup power automatic switching device under light load conditions in substations,this article analyzes two relevant cases,proposes two improvement directions,namely"improving voltage circuit design"and"adding additional starting conditions",and proposes corresponding improvement plans.
