摘要
5G非地面网络(non-terrestrial network,NTN)是当前最先进的星地融合、空天一体化通信技术,是地面5G通信移动系统面向卫星通信和低空通信等新应用场景的主流技术。研究5G NTN关键技术及应用对数智化坚强电网建设具有重要意义。文章在深入阐述新型电力系统面临的形势与挑战的基础上,深入分析5G NTN关键技术特性及应用场景,结合当前新型电力系统电力业务盲区通信需求,提出电力5G NTN技术应用架构,构建面向电力业务的星地融合通信系统,并给出星地融合通信系统在电力行业应用的测试结果,最后展望了电力空天地一体化技术演进及发展趋势。将5G NTN技术与电网深度耦合赋能新型电力系统构建,提供电力多业务承载与信息交互的坚强空天一体通信保障,为空天地一体化电力通信网建设奠定基础。
5G non-terrestrial network(NTN)is the most advanced satellite-terrestrial and air-space integrated communication technology,and is an important technology for terrestrial 5G communication systems for new application scenarios such as satellite communication and low-altitude communication.It is of great significance to study the key technologies and applications of 5G NTN for the construction of a digital,intelligent and strong power grid.On the basis of in-depth exposition of the situation and challenges faced by a new type of power system,this paper deeply analyzes the key technical characteristics and application scenarios of 5G NTN,combines the current communication requirements of a new type of power system’s service blind zone,proposes an application architecture of power 5G NTN technology,builds a satellite-terrestrial integrated communication system for power services,and gives the application test results of the satellite-terrestrial integrated communication system in the power industry,and finally looks forward to the evolution and development trend of power air-space-earth integration technology.The deep coupling of 5G NTN technology with the power grid empowers the construction of a new type of power system,provides a strong air-space integrated communication guarantee for power multi-service carrying and information interaction,and lays the foundation for the construction of a power integrated communication network of air, space, and earth.
