摘要
随着我国特高压建设和全国联网工程的不断推进,传统的输电系统在适应现代电网发展过程中出现一定的局限性,智能输电系统的建设将是我国电网建设的重要任务。文章分析了建设智能输电系统的动因,提出了适应于我国智能输电系统的结构和功能特点。首先介绍了电力通信系统的特点和传输的内容,然后分析了智能变电站的技术特征和集成自动化系统的结构,总结了建设智能输电网络的核心技术,列举了输电控制中心的基本功能、扩展功能和备用功能,提出了后智能电网时代我国输电网的发展问题应该成为智能输电系统规划建设考虑的问题之一。
With inceasing development of nationwide power grid interconnection and construction of UHVAC/ UHVDC power transmission projects, the construction of smart power transmission systems will be the vital task in China＇s power grid construction, however, traditional power transmission systems are indicative of certain limitation during the adaptation of them to the development of modem power grids. In this paper, the authors analyze the reasons of constructing smart power transmission systems, and propose the structure and functional characteristics in adaptation to smart power transmission systems in China. Firstly, the features and transmitted contents of power communication systems are presented; then the technical features of smart substations and the structure of integrated automation systems are analyzed; the core technologies for the construction of smart power transmission network are summarized; the basic functions, extended functions and alternate functions of power transmission control center are enumerated, and finally it is pointed out that the development of China＇s power transmission networks in the post-smart power grid era should be the problem to be considered in the planning and construction of smart power transmission systems.
