摘要
基于分布参数热工对象的集总参数化动力学模型,对自然循环蒸汽发生器进行了控制体划分并建立了数学模型,并用MATLAB语言和SIMULINK仿真软件对其进行了仿真,文章采用了Runge-Kutta(4,5)求解器,得到不同功率装置运行时,一次侧,二次侧,以及管束的温度分布,并得到一回路给水扰动时,传热量以及冷却剂出口焓的响应曲线。
Based on lumped paramerer dynamic model of distribution parameter thermal system, the paper established the control volumes and mathematical models to natural circulation type steam generator. The models were simulated with software MATLAB and SIMULINK. Adopting Runge-Kutta（4,5） scheme, the paper educed primary side, secondary side and tubes temperature distribution at different power conditions, also the response curve of heat transfer and coolant outlet enthalpy while primary side feedwater was disturbing.
