通过对中国发电能源与电力需求分布的客观条件以及特高压交直流输电技术性能的综合分析，系统论述了中国特高压电网的发展特征、结构特点及其成因，探索并揭示了特高压电网发展的内在规律，结合中国电力发展的布局和发展前景，进一步论证了未来形成“三华”特高压同步电网的客观必然性，结合大型能源基地开发和特高压交直流技术特性，提出了交直流并列输电的理由，并分析了能源基地开发对特高压骨干网架的影响。

Analysis on the Development Strategies of the UHV Grid in China

In the paper, analysis is given on the conditions of the distribution of the resources for electricity generation and the electricity demands as well as the technical properties of ultra-high voltage (UHV) AC/DC transmission technologies in China. A systematic discussion of the structural features and the originality of UHV grids are made. And an exploration of the development of UHV and the internal reason to form the Three-Hua synchronous grid (the large synchronous UHV grid connecting North China, Central China and East China Grid) are conducted. The reason to employ parallel AC/DC transmission and the impacts of developing energy bases on the main network structure of the UHV grids are analyzed.
