| 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。 |

| Abstract: |
| 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. |
