摘要

备自投是变电站常见的一种二次保护设备,通过甘肃某地级市110 kV两线两变内桥接线变电站改造为三线三变扩大内桥接线变电站为例,提出一种采用两套常规备自投装置实现三线三变扩大内桥接线变电站的备自投逻辑,并给出了桥备自投、线路备自投及两种备自投相结合的逻辑分析,实际运用表明,该方法简单实用,对于实际110 kV变电站的新建或者改造有很好的指导意义。
        The spare power automatic switching is a kind of secondary protection equipment commonly used in substations. Taking the transformation of 110 kV two-line two-variable inner bridge wiring substation in certain prefecture-level city of Gansu into a three-line threevariable expanded inner bridge wiring substation as an example, this paper proposed a kind of two set of conventional spare power automatic switching devices to realize the spare power automatic switching logic of three-line three-variable expanded inner bridge wiring substation and gave the logical analysis of bridge spare power automatic switching, circuit spare power automatic switching and the combination of two kind of spare power automatic switching. The practical use shows that this method is simple and practical, and has a good guiding significance for the construction or transformation of the actual 110 kV substation.
