大跨越导线与塔高经济性优化研究

Research on economical efficiency optimization of large crossing high power line and tower height

介绍了铁塔经济性高度优化原理及大跨越线路成本建模的方法。通过建立数学模型,以总费用为目标函数,以载流量校验、电压降校验以及电晕校验等形成约束条件,以导线型号、导线类型、铁塔类型组成设计空间,计算出最优的组合。通过具体的实例来分析,得到了经济性优化跨越塔塔高及导线。

Our transmission line project is in full swing,but studies of large span economical optimization very few,be badly in need of theoretical guidance. To this end,this paper introduces in detail the tower economy highly optimized principle and method of large cross line of cost modeling. By establishing a mathematical model,with the total cost as the objective function and with current carrying capacity check、voltage drop check and corona checksum formed to constraints and with the wire type,tower type composition of the design space to calculate the optimal combination. Finally,through the analysis of specific examples to get the economical efficiency optimization of large crossing tower height and large crossing power line type. This topic can offer tower choice and conductor selection optimization opinions to large cross line construction,guidelines for the large cross line construction play a bigger role.
