摘要
导线选型是交流特高压输电的关键技术之一,对线路建成投产后的安全运行及经济运行有着非常重要的影响。根据拟定的输送容量、电磁环境、运行温度、安全系数等边界条件,对16种导线进行了全面的电气性能及机械性能对比。同时,根据国内不同性质电源(火电、水电、核电、风电)的特征,选取与之匹配的单位千瓦补充投资、上网电价、年运行小时数等参数进行了年费用分析,有针对性地给出了推荐建议,为工程建设提供参考。
Conductor selection is one of the key technologies of UHVAC power transmission, which has a very important influence on the safe operation and economic operation of the line. According to the boundary conditions, such as transport capacity, electro- magnetic environment, operating temperature, safety factor, the paper makes a comprehensive comparison of the 16 kinds of wires in the electrical and mechanical properties. At the same time, according to the characteristics of different nature of power supply （ thermal power, hydropower, nuclear power, wind power）, the selection and matching of the units of the supplementary investment, ac- cess to electricity, the number of hours per year, and other parameters for the annual cost analysis, the proposed recommendation for the construction of engineering.
