碳纤维复合芯导线在新建500 kV工程中的应用

Application of Carbon Fiber Composite Core Conductor in New 500 kV Project

以新建500 kV双回线路工程为案例,针对4×JL/G1A-630/45钢芯铝绞线的基本导线方案,选取了7种碳纤维导线,进行了电气性能、机械性能及经济性能分析。采用年费用分析法,计算了碳纤维导线与基本导线年费用平衡时的导线价格比,并研究了年费用平衡点时导线价格比与损耗小时、电价、利率、静态投资的关系。

In this paper,a new 500 kV double loop line is taken as an engineering case. According to the basic scheme of 4 × JL/G1 A-630/45 ACSR conductor,7 kinds of carbon fiber composite core conductor are selected. The electrical performance,mechanical performance and economic performance are analyzed. The annual cost method is used to calculate the wire price ratio of annual cost balance between the carbon fiber composite core conductor and the ACSR conductor. The relationship between wire price ratio and loss hour,electricity price,interest rate and static investment is studied.
