摘　　要：普通配电变压器改造为经济型配变时,需要对多个变压器改造优先级进行合理评估排序。提出一种基于模糊层次分析法的配电变压器改造优先级评估方法,通过建立改造优先级评估的层次结构模型,选取典型评价指标,确定各层间的权重,构建模糊一致判断矩阵,计算各待改造配变的综合评价值及排序。某电网的应用实例证明该方法可为配变改造优先级评估提供更科学的决策参考。Priority of distribution transformers replacement should be assessed and sequenced reasonably when ordinary distribution transformers replaced by economical types.A priority assessment method for distribution transformer replacement based on fuzzy analytical hierarchy process（FAHP） is proposed in this paper.The hierarchical structure model of priority assessment is established,the typical evaluation factors are selected and the weight of each layer is determined.Fuzzy consistent judgment matrix is constructed to calculating the comprehensive evaluation value and ranking them of each distribution transformer.The actual application shows that this method can provide more scientific decision-making references for assessing replacement priority.
