Abstract

The invention relates to the technical field of transformers, and discloses an operation control method and device of a transformer, equipment, a medium and a program product, and the operation control method of the transformer comprises the steps: obtaining oil temperature data of a plurality of orientations in the transformer in a first preset time period, and carrying out the feature extraction and fusion of the oil temperature data of the plurality of orientations, obtaining target oil temperature data in a first preset time period; analyzing the uniformity degree of the target oil temperature data to obtain a first target temperature entropy of a first preset time period; the first target temperature entropy is used for representing the uniformity degree of oil temperature distribution of the transformer; and judging whether the first target temperature entropy of the first preset time period is smaller than a first preset value or not, and if the first target temperature entropy of the first preset time period is smaller than the first preset value, controlling the transformer to operate normally. And the accuracy of transformer fault judgment is improved.
