摘　　要：金沙江一期工程包括溪洛渡和向家坝2座水电站,总装机26台,容量18600MW,计划2012年开始投产,2017年全部建成。为配合溪洛渡和向家坝水电站可行性研究,开展了金沙江一期工程输电系统规划设计,经过大量的分析论证,推荐其输电系统采用3回±800kV直流输电方案,每回规模6300MW左右。溪洛渡左—株洲±800kV直流输电工程是金沙江一期直流输电工程的重要组成部分,落点湖南电网,具有电压等级高、输送容量巨大的突出特点,接入系统方案对受端电网的影响显著。结合直流工程的供电范围和受端电网的网络规划,对株洲换流站接入系统方案进行综合分析,并对与接入系统方案有关的问题进行分析。Jinshajiang phase I project is made up of two hydraulic power plants, Xiluodu and Xiangjiaba, totaling 26 generators with a capacity of 18 600 MW. This project will go into operation in 2012 and be completed entirely in 2017. As an important part of the feasibility study of the project, the transmission system planning has been made. Based on massive analyses and demonstrations, it is suggested that the transmission system of Jinshajiang phase I should be made of three ±800 kV ultra high voltage DC （UHVDC） transmission lines, with 6 300 MW on each line. Xiluodu Left Bank-Zhuzhou ±800 kV DC transmission project is an important part of the transmission system. Zhuzhou converter station, the inverter station, is located in Hunan province. Hunan grid is the receiving end with a very high grade voltage and a great transmission capacity. System connection schemes will greatly influence the receiving end power grid. Based on the power supply area of the project and the planning of receiving end power grid, the system design schemes of Zhuzhou converter station and relevant problems are comprehensively analyzed.
