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.
