Power grid fault analysis method and system

The invention belongs to the field of power grid fault analysis, and provides a power grid fault analysis method and system, and the method comprises the steps: obtaining operation parameters corresponding to a power grid fault, and carrying out the preprocessing; based on the preprocessed operation parameters, performing fault analysis by using a pre-trained power grid fault analysis model; wherein the step of carrying out fault analysis by utilizing the pre-trained power grid fault analysis model specifically comprises the following steps: carrying out clustering based on the preprocessed operation parameters; performing feature extraction according to the clustered operation parameters to obtain clustered operation parameter features; fault classification and identification are carried out based on the clustered operation parameter features; and obtaining a power grid fault analysis result according to the fault classification identification result. According to the method, the power grid fault data is clu
