摘　　要：根据电力变压器运行状态信息的不完全性,采用层次分析法(AHP)建立和量化变压器状态评估的层次指标,优化状态信息不完全性。引入灰色定权聚类对变压器状态进行灰色分类,建立灰色白化权函数。把AHP与灰色定权聚类相结合,能更准确地对变压器进行定性和定量状态评估。实例分析表明,基于AHP灰色定权聚类的电力变压器状态评估方法是合理和可行的。Aiming at the incompleteness of operational condition information of power transformer,AHP（Analytic Hierarchy Process） method is applied to establish and quantify the level index of transformer condition assessment for its optimization.A grey fixed-weight clustering algorithm is introduced to classify the power transformer conditions and establish the whitening weight function of grey.The combination of AHP and grey fixed-weight clustering algorithm can assess the transformer condition more accurately,qualitatively and quantitatively.Practical case study shows that,the proposed method is reasonable and feasible.
