智能电网高度兼容的电力接入能力、安全可靠性、灵活可控性将极大提高我国电网的安全稳定运行水平。根据我国未来形成的“三华”特高压同步电网的现状，分析了我国大型互联电力系统发展智能电网的必要性，对我国输电系统智能电网发展现状进行了综述，提出了我国输电系统智能电网发展的建议。

In view of the characteristics, such as highly compatible power access capability, high security and reliability, and great flexibility and controllability, the application of smart grids in power transmission systems will improve both operation security and stability of power grids in China. Based on the development conditions of the Three-Hua UHV synchronous power grid, which connects North China, Central China and East China Grids, the necessity of applying smart grids to large-scale interconnected power systems in China is analyzed, the current development status of smart grids in domestic power transmission systems is reviewed, and suggestions on the development of smart grids in China are provided.
