Simulation-based fault feature extraction system and method, storage medium and equipment

The invention relates to a simulation-based fault feature extraction system and method, a storage medium and equipment, and aims to solve the problems that the current engine fault diagnosis depends on a large amount of fault data, the real-time performance is relatively insufficient, and dynamic detection and diagnosis of fault development are difficult to meet. The system comprises an engine system simulation model generation module, an extraction condition setting module, a model simulation solving module, a post-simulation result processing module, a feature extraction module and a fault feature library. The method comprises the following steps: 1, acquiring a normal simulation model and a fault simulation model of an engine system, and performing simulation solution; 2, extracting real-time data in simulation or post-simulation result data; 3, performing dynamic feature data extraction or steady-state feature data extraction on the data extracted in the step 2; 4, processing the data extracted in the ste
