摘　　要：介绍荆门变电站是1000kV晋东南—南阳—荆门交流输变电工程的一部分,作为特高压电网的重要枢纽点,其落点位置及接入系统方案对华中区域电网的发展有着深远的影响。结合特高压骨干电网规划及华中电网“十一五”500 kV电网规划,对1000kV荆门变电站落点位置进行综合分析研究,并进一步对其接入电网方案进行技术经济比较和分析,提出推荐意见。同时对湖北鄂西-鄂东断面输送能力、荆门近区网架优化等相关问题进行研究。As a part of the 1 000 kV Jindongnan-Nanyang-Jingmen UHVAC transmission project and a key point in the ultra-high voltage grid of China, the location and system scheme of 1 000 kV Jingmen substation has a great influence on the development of central China power grid. Based on the ultra-high voltage grid plan and the 11^ th Five Year Plan of central China 500 kV power grid, a comprehensive study on the location of Jingmen substation was made. The system scheme of Jingmen substation was introduced by the technical and economical analyses and comparisons. Relevant studies such as the transmission ability between west and east Hubei grid and the optimization of the adjacent grid of Jingmen substation were also made.
