分布式电网二次设备管控平台的研究 黄学庆 夏友斌 潘文虎 苏志朋 宋铭敏 （国网芜湖供电公司，安徽芜湖 241000 ） 摘要 针对目前电力系统二次设备存在无法管控的问题，本文提出一套新型分布式电网二次 设备管控平台，通过部署在机房和变电站内的监控、代理服务器，实现调度数据网和变电站二次 设备运行状况的实时监测和管控。平台采用分布式架构，关键节点离线后，系统可解列独立运行。 该平台基于Liunx 系统及B/S 架构，并通过 SNMP 技术获取网络拓扑及设备状态，以此提供智能 告警功能，支持告警定制，满足各种业务需求，具有可靠、安全、高效的特点。 关键词：二次设备；SNMP；交换机；调度数据网 Research on the Distributed Control Platform of Secondary Equipment in Power Grid Huang Xueqing Xia Youbin Pan Wenhu Su Zhipeng Song Mingmin (State Grid Wuhu Power Supply Company, Wuhu, Anhui 241000) Abstract A new distributed control platform for secondary equipment in power grid is proposed in this paper to solve the monitoring problem. The monitoring server and proxy server are deployed in the server room and substation respectively, which the operating conditions of secondary equipment in dispatching data network and substation could be monitored and control on the real time. The distributed architecture is adopted in this control platform, when the key node is offline, the system could be disassembled, and run independently. The platform is based on Linux system and B/S architecture, and with SNMP technology the network topology and equipment status could be obtained. The intelligent alarm function is provided in the platform, which support the alarm information customization, and has reliable, safe and efficient features.
