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. |
