220kV备用电源自动投入装置应用

Principle and application of 220 kV automatic bus transfer equipment

以佛山市220kV桃源变电站为例,介绍了备用电源自动投入装置(简称备自投装置)的主要功能及工作原理。详细分析了桃源变电站3种运行方式的判断策略、有关定值设定、装置闭锁和异常判断。具体给出了联切110kV出线开关、旁路代路和线路检修情况下备自投装置的动作程序。现场运行成功地实现了备自投装置的自动检测,智能化断、合相应开关及联切负荷。

With Taoyuan 220 kV substation of Foshan as an example, the working principle and main functions of automatic bus transfer equipment are introduced. Judgment strategies, relevant settings,blocking and abnormity state determination are analyzed in detail for its three operating modes. Action procedures of automatic bus transfer equipment in cases of 110 kV out-going switch operation,shunt switch operation and line inspection are offered. Functions of automatic detection, intelligent switching on-off and load rejection are realized on site.
