The present application relates to a
transformer fault diagnosis method based on improved
sparrow search algorithm optimization SVM, through the pretreatment and
feature engineering of
transformer oil chromatographic data; according to the data of pretreatment and
feature engineering, the model based on oil chromatographic data is constructed, and the
model parameters are optimized and trained; the input
transformer oil chromatographic data is carried out transformer fault diagnosis based on the optimized and trained model.The present application improves the
sparrow search algorithm by introducing the best
point set strategy, the golden regular update rule, the differential
mutation disturbance and the reverse learning mechanism, so as to comprehensively improve the parameter optimization process of
support vector machine, the global exploration ability of the
algorithm is enhanced, the risk of falling into
local optimum is avoided, and the problem of
premature convergence is effectively avoided.In addition, the
improved algorithm pays attention to multi-link optimization, and the parameter setting is simple, the
algorithm is low in use difficulty, so that the optimized
support vector machine (SVM) can effectively improve the transformer fault prediction precision.
