基于灰色关联法的导线综合选型分析研究

Analysis and Research on the Comprehensive Selection of Wire Based on Grey Correlation Method

摘要: 随着用电负荷不断增高，输送容量越来越大，线损带来的经济损失越来越高，对于导线的增容、节能有了更高要求。本文首先将导线选型的基本指标分为成本型和效益型指标，在此基础上，简述如何将灰色理论中的灰色关联分析方法应用于导线选型之中，然后具体运用灰色关联分析方法对导线的成本型指标和效益型指标进行了评价和比较，并结合导线的经济性能进行综合的分析与讨论，最后得出导线选型的最优方案。结果表明灰色关联分析方法应用于导线选型中的正确性和有效性。

Abstract: Along with the load increasing, the transmission capacity is growing, the economic loss caused by line loss is getting much higher .So a higher demand is asked for the wire capacity, energy saving. In this paper, the basic index of wire selection is divided into cost and benefit index. The gray relation analysis method in gray theory is applied to the selection of wire. Then we use the gray correlation analysis method to evaluate and compare the cost index with benefit index, while the economic performance of the wire is analyzed and discussed synthetically. Finally, the optimal scheme of wire selection is obtained. The results show that the gray relation analysis method is applied correctly and validly to the wire selection.
