北京地铁1、2号线变电站自动化系统方案

基于网络化结构下的分层分布式系统的实践,使变电站自动化系统的结构和性能发生了重大的变化,提出一种实现变电站全站自动化的方案,应用于北京地铁1、2号线地铁变电站自动化系统。基于分层分布式系统下的系统构成,该系统按纵向分为网络管理层、数据传输层和基础设备层。重点介绍了通信网络的构成,网络管理层基于TCP/IP的以太网络通信,采用站内103通信规约,数据传输层以通信服务器为核心,向下采集其他智能设备数据,支持任何采用103规约及采用Modbus通信规约、pro-bus通信规约或采用TCP/Modbus协议的智能设备,并将采集到的数据转换成以太网双网数据,通过交换机上传至监控系统及调度中心。该系统采用NDT650监控系统软件,完成地铁变电站自动化系统实现的各种功能。

Scheme of substation automatic system for Beijing subway No.1 and No.2

The implementation of layered and distributed system with network structure changes the topology and performance of substation automation system greatly. A whole substation automation scheme is proposed and applied to Beijing subway No.1 and No.2,which is divided into network administration layer,data transmission layer and basic equipment layer. The communication network is emphasized. The network administration layer is based on Ethernet with TCP / IP and in-station 103 protocol. Taking the communication server as the core,the data transmission layer collects data from other intelligent devices with 103 protocols,Modbus protocols,pro-bus protocols or TCP / Modbus protocols,which are converted as dual Ethernet network data and then transmitted to monitoring system and dispatch center via hub. NDT650 monitoring software is used to realize different functions of substation automation system for subway.
