Abstract

The invention provides a method, a device for evaluating the health state of a distribution transformer, a medium and a program. The method for evaluating the health state of the distribution transformer comprises the following steps: extracting features from power parameters of a plurality of distribution transformers; clustering the plurality of distribution transformers into M subsets based onthe extracted features, wherein M is a natural number greater than 1 and less than the number of distribution transformers; for each subset in the M subsets, executing the following processing: determining a clustering center of the subset as a reference transformer of the subset; calculating the similarity between each distribution transformer in the subset and a reference transformer; and sorting the distribution transformers in the subset according to the calculated similarity.

Description

technical field [0001] The present invention relates generally to the field of transformers, and more particularly to methods, apparatus, devices, media and programs for assessing the condition of distribution transformers. Background technique [0002] The health of distribution transformers can be understood as high reliability and small power loss. However, it is difficult to give a clear definition on how to evaluate the health status of distribution transformers. [0003] At present, the health evaluation of transformers mainly focuses on the condition monitoring and maintenance of high-voltage transformers and equipment reliability evaluation, and some transformer condition evaluation methods have been proposed. However, these methods are based on fault or event data, or monitoring data inside the transformer, and these methods are based on individual devices. Contents of the invention [0004] A brief overview of the invention is given below in order to provide a ...
