Abstract

The invention discloses a transformer fault diagnosis method and system based on an intelligent integration algorithm, and the method comprises the steps: carrying out the preprocessing of obtained oil chromatography data, and carrying out the feature construction of the preprocessed oil chromatography data, so as to obtain a plurality of features; respectively determining input characteristics corresponding to different types of transformer fault diagnosis algorithms; constructing a transformer fault mode diagnosis model based on an intelligent integration algorithm according to the determined input features corresponding to the different types of transformer fault diagnosis algorithms; determining the fault diagnosis accuracy of each transformer fault mode diagnosis model in each fault mode, and determining an algorithm corresponding to each fault mode and the weight of each algorithm according to the fault diagnosis accuracy; and utilizing the transformer fault mode diagnosis modelbased on the intelligent integration algorithm to diagnose oil chromatography data to be diagnosed, determining a fault mode result, and determining a diagnosis result according to the priority coefficient of each fault mode in the fault mode result.

Description

technical field [0001] The present invention relates to the technical field of electric equipment fault diagnosis, and more specifically, to a transformer fault diagnosis method and system based on an intelligent integrated algorithm. Background technique [0002] In recent years, the proportion of electric energy consumption in the entire energy industry has been increasing year by year. Ensuring the safe and stable operation of the power grid is an important condition for maintaining and promoting economic development. Transformer is an important device in the power grid and an important carrier to realize power conversion and reduce power loss. Timely detection of potential failures and ensuring its safe operation can effectively reduce the probability of power grid failures. With the development of data mining technology and machine learning technology, distribution transformer intelligent fault diagnosis technology has gradually been researched and applied. Intelligent...
