通过综述和现状分析,总结当前我国特高压外送通道的发展现状,目前已投运特高压工程共计39个,包括19个交流工程,20个直流工程。结合沙戈荒基地发展,分析特高压通道存在输电效率降低、配置大量火电挤占一定输电空间、输电通道和站址资源日趋紧张、多项工程并行配套保障压力大、关键技术存在短板等问题,并提出相关建议:首先应加强顶层设计,统筹全国合理布局特高压工程;其次应加强关键核心技术创新和应用,加大柔性直流特高压技术的研发与应用;最后应强化特高压工程应与其他产业融合发展。

Through literature review and current situation analysis,this article summarizes the current development status of ultra-high voltage transmission channels in China. A total of 39 ultra-high voltage projects have been put into operation,including 19 AC projects and 20 DC projects. Based on the development of the New Energy Base on the Desert,this paper analyzes the problems of reduced transmission efficiency,large allocation of thermal power occupying a certain amount of transmission space,increasingly scarce transmission channel and station resources,high pressure on parallel support of multiple projects,and shortcomings in key technologies in ultra-high voltage channels. And put forward relevant suggestions: first,strengthen top-level design,coordinate the reasonable layout of ultra-high voltage projects nationwide,second,strengthen innovation and application of key core technologies,increase research and application of flexible DC ultra-high voltage technology,and finally,strengthen the integration and development of ultra-high voltage projects with other industries.
