Transformer sample capacity expansion method, computer equipment and computer readable storage medium

The embodiment of the invention discloses a transformer sample capacity expansion method, computer equipment and a computer readable storage medium. The method comprises the following steps that a first data set is generated according to first transformer operation data, the first transformer operation data are transformer operation data collected under the real condition, and the first data set comprises a plurality of first samples and first category labels corresponding to the first samples; the first sample set is learned through a preset algorithm and then expanded, a second sample and a feature vector average value are obtained, and the second sample is transformer operation data generated through simulation; calculating according to the feature vector average value to obtain a confidence coefficient threshold value, and screening the second sample by using the confidence coefficient threshold value to obtain a third sample; the first sample and the third sample are merged to obtain a second data set.
