变压器健康状态评估的灰色聚类决策方法

Method of Grey Clustering Decision-making to State Assessment of Power Transformer

电力变压器健康状态的评估是实现变压器状态维修的重要一步,研究变压器的状态评估具有重要的现实意义。电力变压器可以看作是典型的灰色系统,提出了采用灰色聚类决策方法对变压器健康状态进行评估,给出了变压器健康状态的灰色分类,建立了灰类的白化权函数,分析了评估变压器健康状态所涉及的状态信息,给出了变压器健康状态评估的灰色聚类决策步骤。实例分析表明,该方法针对变压器健康状态的评估提供了一种新的途径。

The assessment of health state of power transformer is a key step to realize Condition-based Maintenance of transformer. Research on health state assessment of transformer has very important actual significance. Transformer can be recognized as a typical grey system. The assessment of its healthy state using grey clustering decision-making method is put forward. The grey classes of transformer are given, the whitenization weight function of grey classes is established, the information involved in assessing the state of transformer is analyzed, and finally steps of state assessment of transformer using grey clustering decision-making are presented. The analysis of actual example demonstrates that the method has provided a new method to assess the health state of transformer.
