摘要
介绍了增加导线截面的降损效果和采用经济电流密度选择导线截面;根据线损率选择更新导线的线路,将待选的每条线路看成一个单独的降损方案,计算每个降损方案的成本;然后,采用改进的隐枚举法得到最优的降损组合方案,介绍了隐枚举法的求解过程和局限性,以及通过改进并应用在选择降损组合方案中;通过算例说明采用隐枚举法解决实际问题的效果。
The aim of the research is to make the best use of the limited funds, through choosing section of line （SOL） reasonably and to make sure the line which to be replaced, enable the effect of reducing energy loss （REL） to be optimized. First, it introduced the effect of REL of adding SOL and using economic current density to choose SOL. Secondly, to choose the line which to be replaced based on line loss rate, make every candidate line as a separate REL program, calculate the cost for every REL program. Then, to get the optimal REL combination program, it showed the solving process and limitation of implicit enumeration （IE） method, through being modified and apply it to how to choose REL combination program. Finally, it gave an example to explain the effect of adoping IE method to solve practical problem.
