摘要
为满足船用小型凝汽器快速实时仿真的需要,根据凝汽器的工作原理和基本的质量、能量守恒方程进行了合理假设,建立了船用小型凝汽器的动态数学模型,借助Matlab/Simulink仿真平台对其进行了动态特性仿真。结果表明,凝汽器各个参数的变化趋势与理论变化趋势一致,可以满足凝汽器动态特性实时仿真的要求。该数学模型可与蒸汽发生器模型、汽轮机模型等一起构成船舶热力系统仿真平台。
In order to meet the need of fast real time simulation of a small marine condenser,the dynamic mathematic model of a small marine condenser is presented according to its working principle and the mass and energy conservation equations as well as some reasonable assumptions.Matlab/Simulink module is used for the dynamic characters simulation of condenser.Result shows that the dynamic trend of main parameters of the condenser is consistent with the theory trend,and can satisfy the need of real time simulation of the dynamic characters of condenser.The presented model of a small marine condenser could constitute the simulation platform of marine thermal system with steam generator model,turbine model,and so on.
