基于光纤光栅OPPC的城区箱变监控系统的研究

The Study of Urban Box-type Substation Monitoring System Based on Fiber Grating OPPC

为加强箱式变电站安全监管,研究一套箱变内置监控系统,采用嵌入WEB服务器监控终端,采集电能、环境温湿度、开关温度等数据,利用光端机和FAP保护盘实现OPPC光缆远距离传输。终端在接收传输数据的同时,还可以监测线路的应力与温度信息,监控室内借助浏览器或APP实时监控。试验验证,OPPC光缆传输耐受恶劣环境能力强,故障时短信报警、界面自动跟踪并可远程切除故障。

To strengthen the safety supervision of box-type substation,a built-in box-type substation monitoring system is studied.The box-type substation is equipped with embedded WEB server monitoring terminal,it collects a variety of data including energy data,environmental temperature and humidity,switch temperature and so on,monitoring terminal uses OPT and FAP protection disc to achieve long distance transmission of OPPC cable.Because OPPC cable is equipped with fiber grating,the terminal can not only receive the transmission data,but also monitor the stress and temperature information of the line,monitoring room achieves real-time monitoring with browser or APP.Test proved that the capacity of tolerating harsh environments of OPPC cable transmission is strong,when the fault occurs,SMS will alarm,interface will automatically track and the fault can remotely be removed.
