摘　　要：全球能源互联网是实现世界范围内能源资源优化配置的路径,亚洲电网互联是全球能源互联网的重要组成部分。亚洲区域内能源资源分布不均衡,大规模电力需要通过远距离输电通道送至负荷中心,到2030年,亚洲区域跨国电力输送将达到250 GW左右。基于对输电技术发展趋势的判断,提出了亚洲特高压交流同步电网、特高压直流送电和直流电网3种亚洲电网互联模式,从系统安全性、对当地电网发展的影响等角度分析了各种联网模式的技术优缺点,提出了各联网模式对输电技术的需求。建立亚洲电网模式方案决策的层次分析法模型,通过层次分析模型的数学求解,提出直流电网模式是未来亚洲电网互联的可能模式。Global energy internet is the way to realize energy resource optimization in the world. Asia grid interconnection is an important part of global energy internet. Distribution of energy resources in Asia is not balanced and large amount of electric power transferred with long distance lines is necessary. Electric power transferred with inter-regional and inter-national power networks in Asia will reach about 250 GW by 2030. Based on future development trend of electric power transmission technology, three interconnection modes, i.e. UHV AC synchronous power grid, HVDC power supply and DC grid, are proposed. Advantages and disadvantages of these interconnection modes are analyzed, focusing on system security and impacts on local power grid development. Demand of electric power transmission technology is presented. An analytic hierarchy process model is established to select probable interconnection mode. Result of the analytic hierarchy model shows that DC grid mode should be recommended.
