Abstract

The invention relates to a transformer winding state detection method, device and equipment and a storage medium, and the method comprises the steps: carrying out the feature extraction according to a vibration signal of a target transformer winding, and obtaining a feature matrix corresponding to the vibration signal of the target transformer winding; inputting the feature matrix into a preset machine learning model to obtain a feature tag of the target transformer winding; wherein different feature tags represent different deformation levels of the transformer winding; and determining the state of the target transformer winding according to the feature tag. According to the technical scheme provided by the embodiment of the invention, the flexibility of detecting the state of the transformer winding can be improved.

Description

technical field [0001] The present application relates to the technical field of high-voltage direct current transmission, in particular to a transformer winding state detection method, device, equipment and storage medium. Background technique [0002] Transformer is one of the core equipment in HVDC transmission project, and its operating status directly affects the operation of the entire power system. In the case of a short-circuit current generated by the transformer, it is easy to cause deformation of the transformer winding, thus causing mechanical failure of the transformer. If the mechanical failure of the transformer cannot be detected and dealt with in time, it will pose a great threat to the entire power system. In practical applications, it is possible to effectively diagnose whether a transformer is faulty by detecting the state of the transformer winding. [0003] In the related art, when detecting the state of the transformer winding, the voltage signal of ...
