摘要

在实践中，电力变压器（PT）的状态是通过健康指数（HI）来量化的。本文分析并比较了三种不同的计算HI的最新算法。第一种方法使用加权SumModel（WSM），第二种方法基于模糊推理系统（FIS），第三种方法结合了这两种技术，即WSM和FIS。这三种方法在由30个单元组成的PT车队中进行了测试。结果表明，对于相同的PT，每种方法都会产生不同的HI值。因此，PT车队的决策将取决于HI计算的选定方法。这项工作提出通过使用K-means聚类技术来合并每种分析方法中涉及的知识，以克服这一缺点。当不确定要选择的适当方法时，该解决方案可以帮助资产经理就PT的维护计划做出适当的决定。

Health Index for Power Transformer Condition Assessment: A Comparison of Three Different Techniques.

In practice, the condition state of Power Transformers (PT) is quantified by using Health Index (HI). This paperanalyzes and compares three different state-of-the-art algorithms to compute HI. The first one uses a Weighted SumModel (WSM), the second is based on a Fuzzy Inference System (FIS), and the third combines both techniques, i.e.,WSM and FIS. These three approaches are tested in a PT fleet composed of 30 units. Results show that eachapproach produces different HI values for the same PTs. Therefore, decision making regarding the PT fleet willdepend on the selected approach for HI calculation. This work proposes merging the knowledge involved in eachanalyzed approach by using a K-means clustering technique to overcome this drawback. This solution could help theasset manager to make adequate decisions regarding the maintenance scheduling of PT when there is uncertaintyabout the appropriate approach to be selected.
