基于常规变电站备自投原理及应用概述

常规变电站备自投装置的动作逻辑的控制条件可分为三类:充电条件、闭锁条件、起动条件。即在所有充电条件均满足,而闭锁条件不满足时,经过一个固定的延时完成充电,备自投装置就绪,一旦出现起动条件即动作出口,文章即对其工作原理及应用作相对概述,对指导实践具体一定参考意义。

The control conditions of the operation logic of the spare power source automatic switch gear in conventional substation can be divided into three categories： charging condition, locking condition and starting condition. That is, when all the chargingconditions are satisfied and the latching conditions are not satisfied, the charging is completed after a fixed delay, and the sparepower source automatic switch is ready. Once the starting condition is present, the working principle and application of the devicewill be relatively summarized, which has reference significance to guiding the specific practice.
