摘　　要：碳纤维复合芯导线是一种新型的节能型增容导线,具有密度小、强度大、耐热性能好、热膨胀系数小、高温弧垂小、导电率高、线损低、载流量大、耐腐蚀性能好、不易覆冰、与环境亲和等一系列优点,适合于输电线路增容改造工程。针对达拉特电厂1号—4号机组出力受阻问题,提出将三回送出线路更换为碳纤维复合芯导线。经分析计算,正常方式下,电厂1320 MW装机可满出力运行,提高了输送容量;在检修状态下,因受线路热稳定及机组暂态稳定限制,电厂需限制一定出力。在线路设计方面提出了根据输送容量合理确定导线型式及运行温度等建议。ACCC is a kind of new structure energy-saving capacity conductor.It has advantage of light weight,high strength,excellent heat resistance,low thermal expansion coefficient,better high temperature sag,high conductivity,low line loss,great load flow,good corrosion resistance,etc.It is suitable for the modification project of increasing capacity of transmission line.To the situation of output blocked from generator 1 to generator 4 of Dalate Power Plant,this paper replaces three loops out-going lines for ACCC conductor.Through the analysis and calculation,in normal mode,1320 MW capacity of generator can run in the state of full load condition,maintenance mode is required to limit the output,but before the relative transformation,it will improve the conveying capacity.Through the application of Carbon fiber in Inner Mongolia power grid,the paper puts forward the suggestions in terms of design and operation.
