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

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.
