摘　　要：开展节能导线的应用研究,对重覆冰区域风电送出线路的安全、经济运行具有重要意义。以湖南某110 kV风电送出线路工程为例,针对其重覆冰、低损耗小时数的特点,从电能损耗、覆冰弧垂及过载能力、经济费用等方面对3类节能导线、钢芯铝合金绞线和普通钢芯铝绞线进行了应用分析。分析结果表明:在15 mm中冰区和20 mm重冰区,JL3/G1A-400/50型钢芯高导电率铝绞线更优;在30 mm重冰区,考虑弧垂特性和排杆需要,不适合采用节能导线,推荐采用钢芯铝合金绞线。It is of great significance to carry out the application research of energy-saving conductors for the safe and economical operation of wind power transmission lines in heavily iced areas.This paper took a 110 kV wind power transmission line project in Hunan as an example,aimed at its characteristics of heavy icing and low loss hours,the application analysis of three kinds of energy-saving conductors,aluminum alloy conductor steel reinforced and ordinary steel-core aluminum stranded wires was carried out from the aspects of power loss,icing sag and overload capacity,and economic cost.The analysis results show that JL3/G1A-400/50 steel core high conductivity aluminum stranded wire is better in the 15 mm medium ice area and 20 mm heavy ice area,and in the 30 mm heavy ice area,considering the sag characteristics and the needs of the row rod,it is not suitable to use energy-saving conductors,and the aluminum alloy conductor steel reinforced is recommended.
