A method for dynamic fault
simulation of a double-section type catalytic
cracking reaction-regeneralion
system comprises the steps that 1, a knowledge
database is established, and a fault
database is integrated; 2, based on DCS data and process model information of an industrial double-section type catalytic
cracking device, a dynamic model of the double-section type catalytic
cracking reaction-regeneralion
system is established, and a dynamic model
library of the double-section type catalytic
cracking reaction-regeneralion
system is established; 3, basic input data under different operating conditions is obtained according to the knowledge
database, and steady-state working points for
dynamic simulation are calculated; 4, specific fault types are selected from the fault database and converted into input deviations of the dynamic model, and dynamic fault
simulation is performed; 5, an intelligent
fault analysis module is applied to verify the fault types,
simulation results are entered into the fault database to perfect the database. The system for dynamic fault simulation of the double-section type catalytic
cracking reaction-regeneralion system comprises a DCS
data acquisition module, the dynamic model of the double-section type catalytic
cracking reaction-regeneralion system, the knowledge database, the knowledge database and the intelligent
fault analysis module.
