G200 SMU实现多主站的远程通信

IMPLEMENTING WAN COMMUNICATION BY G200 SMU

以新一类网络型变电站监控装置 G2 0 0 SMU(站主装置 )在上海南桥 5 0 0 k V交直流换流站实现 SMU直接上广域网与国调中心和华东网调的 EMS进行通信为例 ,介绍了开放式网络通信方案 (ONCP)的特点 ,分析讨论了 SMU直接上广域网实现方案的技术特点、结构特征及发展趋势 ,并对SMU与多个 EMS及其它系统之间实现远程计算机通信方式的发展提出了看法。

In China a WAN communication from the control system in 500kV Nanqiao high voltage AC/DC converter substation to National Power Dispatching & Communication Centre and East China Dispatching Center is first implemented by G200 Substation Master Unit (SMU). In this paper the technical feature, structure character and development trend of WAN communication implemented by SMU are analyzed. Otherwise, the opinion on how to use G200 SMU to communicate with many EMS and other systems is put forward.
