PWR堆芯动态特性的SIMULINK仿真计算及界面设计

摘要

Applying the thermal reactor core physics model and thermal model, the PWR core of the SIMULINK model was established. The dynamic corresponding rules of the PWR core are discussed under different reactivity disturbance. On this basis, the SIMULINK simulation program GUI man-machine exchange interface is established. GUI interface can Set model pa-rameters, control SIMULINK model and show simulation results, thus making the simulation more intuitive, flexible and fast.%运用堆芯物理热工模型建立了PWR堆芯的SIMULINK仿真模型，探讨了在不同反应性扰动下堆芯的动态响应规律。在此基础上，根据SIMULINK仿真模型建立了GUI人机交换界面，通过GUI界面设置模型参数并控制SIMULINK程序和显示仿真结果，使仿真更加直观、灵活、快捷。
