摘　　要：介绍了欧、美国家电网发展设想,指出其对我国未来电网发展具有一定的借鉴意义和启示,并根据我国未来电源及负荷预测结果,分析了我国2020年、2030年及2050年可能的电力流格局,对我国2020年、2030年输电网发展模式进行了预测,对我国2050年输电网发展模式进行了展望,指出未来我国全国联网是一种必然趋势,2020年及2030年我国电网将主要以交直流超/特高压混合输电网模式发展,2050年我国电网发展模式可能存在交直流超/特高压混合输电网模式、超导主网架模式及电源与负荷匹配模式3种情况。最后总结了我国未来电网发展的关键技术需求。The development ideas of power grid in Europe and America are presented and the inspirations that could be leant from these development ideas for China’s power grid development in future are pointed out.Based on the predicted results of power sources and load in China in future,the possible power stream patterns in 2020,2030 and 2050 are analyzed,and the development patterns of China’s power transmission networks in 2020 and 2030 are predicted and the development pattern of China’s power transmission networks in 2050 is prospected.On this basis,it is pointed out that the nationwide interconnection of power grids in China is an inexorable trend.In 2020 and 2030,China’s power grids will be mainly developed in the pattern of EHV/UHV AC/DC hybrid transmission network,and in 2050 there will possibly coexist three development patterns,namely the AC/DC EHV/UHV hybrid power transmission mode,the superconducting backbone network and the matching pattern between power source and load.Finally,the requirement on key technologies for China’s power network development in future is summarized.
