Abstract
In order to simplify the control system of AP1000 pressurizer in nuclear power plant
a mathematical model was established by using the two-region equilibrium model
on the basis of simplified calculation and field operation data simulator. The disturbances of filling water flow segment were carried out as simulation test
and the results were compared with the simulation results of a nuclear power plant simulation to verify the accuracy of this model.
