摘　　要：介绍了一种实现110 kV串供变电站备用电源自动投入(以下简称"备自投")供电的系统,指出这种系统存在不同站点判别备自投成功的等待延时不同的问题。为此,建立动态延时算法模型,分析开环点和非开环点的各关键要素,提出一种有效的解决办法。实验结果表明,采用该方法的装置在各种模拟故障情况下均能正确判断备自投是否动作成功。This paper introduces a kind of system for realizing power supply of the automatic bus transfer equipment in 110 kV series substation and points out that there is a problem of different waiting delay time for distinguishing success action of automatic bus transfer equipment in different stations.Therefore,a dynamic delay time algorithm model is set up to analyze key factors of open looping points and non-open looping points and effective solutions are proposed.Experimental results indicate that the device using this method could correctly judge whether the automatic bus transfer equipment could act successfully under different simulating faults conditions.
