摘要
导线的选择是超高压输电技术的重要课题,线路的输送容量、传输性能、环境问题对输电线路的技术经济指标都有很大的影响。主要从电气特性、机械特性和投资分析三个方面对各种导线截面和分裂方式进行技术经济比较,特别在导线选型造价分析中按全寿命周期费用分析,而不是只考虑初投资,这样可以全面考核各导线方案的技术经济性,最后推荐出在技术和经济上最优的导线截面和分裂方式。
The selection of conductor is important task in EHV power transmission technology. Transmission capacity, performance, environmental protection of transmission line has great effect upon that of technical ＆ economic index. Technical and economic comparison is made for the conductor section and division mode in view of electric, mechanical character and investment analysis. Life cycle cost analysis is especially adopted for the analysis of conductor type selection, but not only considers initial investment. The analysis can comprehensively evaluate the technical economy of each conductor scheme. The optimal conductor section and split mode are recommended from the aspect of technology and economy.
