船用核动力装置负荷切换控制动态仿真

Dynamic Simulation of Load Switching Control for Marine Nuclear Power Plant

本文以船用核动力装置为研究对象,建立了蒸汽发生器及二回路系统的数学模型及仿真模型。介绍了温度控制和切换控制两种核动力装置负荷协调控制策略,并进行了降负荷工况的仿真研究。研究表明:切换控制对系统参数扰动较大,但低负荷时系统参数皆小于温度控制,并且选取的切换点负荷越低,对系统参数的扰动越小,对系统的设备寿命及经济性有更好的优越性。

In this paper, the mathematical model and simulation model of steam generator and secondary loop system are established by taking Marine nuclear power plant as the research object.Two load coordination control strategies of temperature control and switching control for nuclear power plant are introduced, and the simulation study of load reduction condition is carried out. The results show that the switching control has great disturbance to the system parameters, but the system parameters under low load are smaller than that under temperature control, and the lower the switching point load is, the smaller the disturbance to the system parameters is, which has better advantages to the equipment life and economy of the system.
