新型一体化五防系统在变电站的应用

Application of New Five － prevention Integrated System to Substation

摘要:

在德阳地区各变电站现有五防系统基础上，根据地区电网调度自动化、通信及变电站自动化系统实际情况， 提出一种新型的一体化五防系统构架。其以德阳电网监控中心防误数据服务器生成的多层次防误架构为基础，利用 变电站现有防误资源，实现防误数据集中统一、站间联络线闭锁、集中/就地开票等功能，完善现有五防系统，提升其可 靠性，为地区电网调度控制及变电站安全稳定运行提供可靠保障。

Abstract:

In order to solve the application defects of the existing anti － misoperation locking system，a new five － prevention integrated system is proposed，which takes the realities of grid dispatching automation system，communication system and substation automation system into account． The five － prevention integrated system has multi － level frame based on anti － misoperation data server which is deployed in dispatching and control center，and then the available anti － misoperation resources in substation are utilized，which can realize the functions such as data processing and storage centralization，anti － misoperation locking of tie － lines，producing operation order in substation or centralized control station． It can improve the existing anti － misoperation locking system，enhance its reliability，and provide a reliable guarantee for the safe and stable operation of regional power grid and substation．
