针对实际电网中普遍存在的串行供电网络，提出一种在调度主站实现的区域备用电源自动投入(简称备自投)系统。该系统综合利用全网信息，有效解决串行供电网络故障时的恢复供电问题。系统能自动识别串行供电变电站数目，并且能处理双回线、母联分位运行等情况。文中基于电网调度自动化系统实现区域备自投功能，并利用其调度员培训仿真模块进行区域备自投逻辑测试。系统经过严格的逻辑测试和现场开环测试，已经在永煤电网投入开环运行。

A regional automatic switchover system in the dispatching main station is proposed for serial power supply network that generally exists in an actual power grid.This system that synthetically utilizes information of the whole network, effectively solves the serial power supply network”s fault restoration.This system can automatically identify the number of serial substations and handle such conditions as double lines,open running of bus tie breaker and other problems.The function of regional automatic switchover is realized based on the power grid dispatching automation system,and its dispatcher training simulation module can be used in the regional automatic switchover logic test.After strict logic test and open loop test,the system is put in open loop operation in the power grid of Yongcheng Coal Corporation.
