| Nuclear power plant having unparalleled performance characteristics of other forms of energy,such as the nuclear fuel with high energy density,nuclear fission process does not require oxygen,nuclear power is used as a ship propulsion having a great advantage,and so on,so that a wide range of fields obtained application and development has been rapid.Two nuclear-powered ship loop system is the source of the ship,its performance will directly affect the reliability of the whole ship and maneuverability.Two nuclear power complex loop thermodynamic system configuration,there is a strong coupling between the various devices,systems modeling and simulation debugging workload,current simulation study of the nuclear-powered two-loop thermodynamic system is mainly concentrated in the areas of nuclear power plants,nuclear-powered ship dynamic Simulation of two-loop thermodynamic system is relatively small.In this paper,a mathematical model of each device is designed for the subject of marine nuclear power Secondary Loop simulation object,using Matlab / Simulink simulation software for the mathematical model for secondary modeling;according to the structure and system simulation model objects connection principle simulink model to connect each device to complete the whole nuclear power simulink modeling two-loop thermodynamic system;see land for the design of nuclear-powered two-loop thermodynamic system with a nuclear power plant control system research and submarines operating mode,and the establishment of simulink model of the system control.Two key parameters of the nuclear power through the loop thermodynamic system is mainly designed to compare the device with the simulated conditions and 81.3 percent rated conditions,the results show that the error is small comparison shows the steady-state simulation platform to meet the accuracy requirements.Using simulation platform dynamic characteristics of the system were studied lifting loads,dynamic simulation results of the analysis of the condition of the main parameters of the device,the results showed consistent with the theoretical analysis shows the validity and feasibility of the system design simulation model control strategy sex.Then change the system part of the control parameter setting goals,study its effect on the dynamics of the performance of two nuclear power loop thermodynamic system.Research on the follow-up study of nuclear-powered two-loop thermodynamic system laid the foundation for the development of new control strategies,operational optimization and visualization to provide platform support. |
