This paper conducts modeling and simulation of a nuclear power cogeneration unit system, and analyzes the impact of feedwater pump cavitation through important transient conditions such as steam turbine tripping, load rejection, and feedwater pump tripping. The simulation results show that cogeneration The influence of the mode on the NPSH of the feedwater front pump is generally not large, and the NPSH of the feedwater front pump is slightly improved in all working conditions. Provide a reference for the safe and stable operation of nuclear power cogeneration units.
