Fault diagnosis system and method for electric power information system

The invention discloses a fault diagnosis system and method for an electric power information system, and relates to the technical field of fault diagnosis. Acquiring operation data of the power equipment through a data acquisition module; the data processing module extracts features related to the fault type from the preprocessed operation data; the edge diagnosis module screens the fault features of the power equipment in the database and marks the fault features as edge fault features; integrating the edge fault features to generate an edge fault feature set; inputting the edge fault feature set into an edge fault diagnosis model to obtain an edge fault type of the power equipment; the center diagnosis module screens fault features of the power system in the database and marks the fault features as center fault features; integrating the center fault features to generate a center fault feature set; inputting the center fault feature set into a center fault diagnosis model to obtain a center fault type of th
