摘　　要：为探讨输电节能导线的新建与改造策略,通过对比分析铝包钢芯(高导)铝绞线、铝合金芯(高导)铝绞线、中强度铝合金绞线、钢芯高导铝绞线及铝合金芯型铝绞线五种导线在实际工程中的应用,结合导线节能原理,评估了不同电压等级(±800 kV直流、500 kV交流、220 kV交流、110 kV交流)下的输电导线投资运行成本及其节能效果。研究结果显示,铝合金芯型铝绞线在经济性上表现最优,能够在较短时间内通过节能收益覆盖改造成本与新建成本。进一步分析表明,线路长度、年度利用小时数及碳价格是影响成本收益平衡点的关键因素。因此,采用铝合金芯型铝绞线进行输电节能改造,不仅能有效减少电能损失和碳排放,还能带来显著的经济收益,促进输电系统的可持续发展。The research aims to explore the new construction and renovation strategies for energy-saving transmission conductors.By comparing and analyzing the application of five types of conductors in practical engineering,including aluminum-clad steel-cored(high-conductivity)aluminum stranded wire,aluminum alloy-cored(high-conductivity)aluminum stranded wire,medium-strength aluminum alloy stranded wire,steel-cored high-conductivity aluminum stranded wire,and aluminum alloy-cored aluminum stranded wire,combined with the principle of energy-saving conductors,the investment and operating costs of transmission conductors under different voltage levels(±800kV DC,500kV AC,220kV AC,110kV AC)and their energy-saving effects are evaluated.The research results show that the aluminum alloy core-type aluminum stranded wire has the best economic performance,and can cover the reconstruction cost and new construction cost through energy-saving benefits in a relatively short period of time.Further analysis shows that line length,annual utilization hours,and carbon price are key factors affecting the cost-benefit balance point.Therefore,using aluminum alloy core-type aluminum stranded wire for energy-saving transmission transformation can not only effectively reduce power loss and carbon emissions,but also bring significant economic benefits and promote the sustainable development of the transmission system.
