摘要
针对华中地区某500 kV线路增容改造过程中选型的问题,本文基于球形模糊层次法,提出了考虑实际应用场景的增容导线评价选型方法 .评价指标基于增容导线基本特征,从电气性能、热力性能、机械性能及经济性四个方面进行分析,运用球形模糊层次分析法,构建层次分析体系结构,并考虑实际应用场景的影响,将模糊分析理论应用于对比矩阵构建过程,建立满足工程需求的球形模糊对比矩阵,依据球形模糊得分函数进行打分,案例计算结果表明,在输送容量需求大的区域,铝包钢芯耐热铝合金线要优于其他导线.在跨山场景下,碳纤维复合芯软铝绞线优于其他导线.
Based on the spherical fuzzy hierarchy method,this paper proposes a method for evaluating and selecting capacity increasing conductors for a 500 kV transmission line in central China,taking into account practical application scenarios.The evaluation indicators are based on the basic characteristics of the capacity increasing wire,and they are analyzed from four aspects:electrical performance,thermal performance,mechanical performance,and economy.The spherical fuzzy analytic hierarchy process is used to construct the hierarchical analysis system structure,and the influence of practical application scenarios is considered.The fuzzy analysis theory is applied to the comparison matrix construction process to establish a spherical fuzzy comparison matrix that meets the engineering requirements.The scoring is based on the spherical fuzzy scoring function.The case calculation results show that in areas with high transportation capacity demand,aluminium clad steel core heatresistant aluminium alloy wire is superior to other wires.In the cross mountain scenarios,carbon fiber composite core soft aluminium stranded wire is superior to other wires.
