新一代智能变电站通信网络技术应用研究

Application of Communication Network Technology in New Generation Smart Substation

智能变电站是智能电网建设的重要内容之一,也是智能电网6个环节信息交互的关键"支撑点"。系统研究了智能变电站站内信息网络、智能变电站与调控、运检端的骨干通信网络和智能变电站与配、用电侧的终端通信网络,提出了站内信息网络结构简化技术路线和骨干、终端通信网框架建设方案,为新一代智能变电站的研究与建设提供了重要的理论支撑和实践依据,为下一步示范工程的设计与建设提供了重要的指导作用。

As one of the most important parts of smart grid, smart substation is the ＂ key node＂ of information interaction of six links in smart grid as well. The substation information network, the trunk communication network between smart substation and the terminal of regulation, operation and maintenance, as well as the terminal communication network between smart substation and power distribution and consumption were systematically studied. Then, the simplified technology route of substation information structure and the development scheme of the trunk and terminal communication network framework were presented. The research results can provide important theoretical supports and practical basis for the research and development of the new generation smart substation, and also provide important guidance for the design and construction of demonstration projects in the next step.
