The invention discloses a transformer fault diagnosis method and system based on an intelligent integrated algorithm, comprising: preprocessing the acquired oil chromatography data, and constructing the characteristics of the preprocessed oil chromatography data to acquire multiple characteristics; Input characteristics corresponding to different types of transformer fault diagnosis algorithms; according to the determined input characteristics corresponding to different types of transformer fault diagnosis algorithms, a transformer fault mode diagnosis model based on intelligent integration algorithm is constructed; The fault diagnosis accuracy rate under various fault modes is determined, and the algorithm corresponding to each fault mode and the weight of each algorithm are determined according to the fault diagnosis accuracy rate; the oil chromatography data to be diagnosed is analyzed by using the transformer fault mode diagnosis model based on the intelligent integrated algorithm. Diagnose, determine the failure mode results, and determine the diagnosis results according to the priority coefficient of each failure mode in the failure mode results. |
