The invention discloses an automatic generation system and method of a fault recorder file analysis model. The system comprises a data processing unit, a data extraction unit and a model base, whereinthe a CFG (configuration) file and a grid model CIME (common information model specification) file are stored in the model base; the data extraction unit extracts a channel name of the CFG file automatically and transmits it to the data processing unit, the data processing unit formats the channel name and performs word segmentation to obtain a standardized name, a relationship model is established in conjunction with channel type to generate primary devices, and a DMF (distribution media format) file is acquired in conjunction with device parameter information in the CIME file. The channel type is compared with corresponding types in the base to automatically establish the relationship model, protection, switches, busbar, circuitry, transformers and other structures are generated in sequence, chances for judging failure of faults due to not-in-time updating can be slimmed, model configuration accuracy is improved, fault judging precision is improved, and work complexity of manual configuration is relieved with configuration time thereof shortened.
