The invention discloses a fuel cell air system performance rapid matching optimization method and system based on a hydraulic simulation model and electronic equipment, and the method specifically comprises the steps: reflecting power generation characteristics through a galvanic pile model according to the change of a cathode supply condition; an air subsystem model is utilized to reflect the flow resistance characteristic of a loop, the influence of the change of a rotating speed back pressure valve on the flow, temperature and pressure of the loop and the electric consumption characteristic; the operation boundary of the air compressor and the electric pile is determined, and condition matching is provided for follow-up operation; a basic control model is provided, and reliable operation of the fuel cell system and the air subsystem thereof is maintained. According to the method, rapid matching optimization of the performance of the fuel cell air system can be realized, automatic operation of the model is realized by using the plug-in script, and the application range of the hydraulic simulation model is expanded. By using a frame model, the difficulty of matching work is reduced, the modularization of the matching work is realized, and the optimization boundary is defined by exhaustion optimization logic, defining a working condition boundary, defining a reasonable boundary and defining the optimization boundary.
Description
technical field [0001] The invention relates to a method, system and electronic device for fast matching and optimizing the performance of a fuel cell air system, in particular to a method, system and electronic device for fast matching and optimizing the performance of a fuel cell air system based on a hydraulic simulation model. Background technique [0002] The matching simulation and verification strategies for the fuel cell air subsystem in the existing technology are all formulated based on the reference conditions provided by the supplier, and the complex adjustment model is built. In other respects, there must be certain differences, and the reference data often has a large margin reserved, so that the simulation results cannot reflect the actual performance well, there is a large precision deviation, and the subsequent control strategies cannot be used. to the corresponding reference. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pr...
