面向全球能源互联网的天空地协同卫星通信网络架构

Space-ground integrated satellite communication network architecture for global energy internet

全球能源互联网的监测、调度、授时、同步及定位等业务均需要能提供广域覆盖、泛在灵活接入服务的可靠通信网络。针对该需求,首先分析阐述全球能源互联背景下各种新型业务需求及其特点,并总结各种业务的共性数据特征;然后论述卫星通信技术的特点以及与全球能源互联网业务特点与数据传输需求的高度契合性,最终提出融合卫星通信网络的全球能源互联网天空地协同网络体系架构。其以IP技术为基础,各层网络通过星间、星地、星空、空空、空地以及地面有线、无线链路连接起来,构建全球覆盖的一体化网络体系。

The system monitoring and scheduling,time service and synchronization,object location and other businesses of global energy internet all need reliable communication networks,which are able to provide wide area coverage and ubiquitous flexible access services.According to the requirement,various new businesses and their data features with the background of the global energy interconnection were firstly analyzed,and then the unique characteristics of satellite communication technology and how it highly accords with the demands of the global energy internet were discussed.Then a space-ground integrated network architecture by the integration of satellite communication networks was presented.Based on IP technology,each network layer interconnects through various communication links,including satellite to satellite,space to ground,ground cable,wireless link,etc.,and then constitute an integrated network system with excellent global coverage performance.
