基于集对分析法的输变电项目经济效益后评估

摘要

This article firstly introduces set pair analysis into the post-evaluation of economic benefit of power transmission, and puts forward detailed calculated ways and steps of applying set pair analysis into post-evaluation of economic benefit for single project. Meanwhile it uses judgment matrix of hierarchy analysis to determine various index weights. Taking the construction project of a 35KV substation for example, after the post-evaluation of economic benefit the results turn out that this way can make scientific and reasonable evaluation. It enjoys the merits of brief calculation, convenient operation and high credibility.%首次把集对分析法引入到输变电项目经济效益后评价中,提出了应用集对分析法对单一项目进行经济效益后评价的具体计算方法和步骤,并利用层次分析法的判断矩阵确定各指标权重.以某35 kV变电站的建设项目为算例,进行了经济效益后评价,结果显示该方法可以做出比较科学合理的评价,计算简明,便于操作,且可信度高.
