摘要(Abstract):

以往的电力变压器选型往往只关注其经济性,而忽视了技术、环境、社会等因素对选型决策的影响,为此建立了一个涵盖经济、技术、环保和社会性的变压器选型新模型,提出综合评价指标的概念,通过各类型变压器综合评价指标的比较来选择变压器。考虑到各参数具有模糊性、随机性、灰性等不确定性,引入能同时处理多种不确定性的区间联系数理论对模型进行处理。最后结合某变压器选型实例,得到了综合权衡后的最优结果。
Previous model selection of power transformer often focuses on its economical efficiency while ignores the influence of technology, environment and society on selection decision-making. Thus, this paper establishes a new selection model covering economical efficiency, technicality, environmental protection and sociality, and it puts forward the concept of comprehensive evaluation index and selects transformer by comparing comprehensive evaluation indexes of various types of transformers. Considering that the parameters are fuzzy, random, gray and etc, interval contact number theory which can deal with a variety of uncertainties is introduced to process the model. Finally, in combination with a specific transformer model selection, an optimal result through comprehensive weighing is obtained.
