铁路低压电网监测系统结构的研究及应用

Research and application on architecture of Monitoring System for railway LV electric power transmission network

根据铁路低压电网的特点、地理分布和监测内容,提出了两级分布式监测系统结构。第一级是变电所监测系统,它由现场总线、微型计算机和监测站组成,通过公用电话网(PSTN)将各个变电所监测系统连接起来构成电网监测系统的第二级。该结构成功地应用于徐州铁路分局低压电网监测系统,系统能够进行分布式数据采集、可视化监视和数据存储。

It was brought forward the two stages distributed architecture of the monitoring system for railway LVDN (LowVoltage Distribution Network) according to the features and monitor contents of the LVDN. The first stage was SMS(Substation Monitoring System), which consists of field bus, microcomputer and measuring units. The second stage is set upwhen every SMS is joined together with PSTN. The architecture is successfully applied to Xuzhou railway LVDN monitoringsystem, which is able to sample data, to monitor visually and store data in the way of distribution.
