Complexity-based pattern recognition and diagnosis for engineering simulation system of HTR-PM

摘要: 本文通过对高温气冷堆模拟机在运行过程中的12组状态参数进行分析，研究了反应堆在正常运行状态、余热排出系统空气侧温度上升和一回路突然泄漏三种条件下系统的复杂度和稳健性等指标的变化．研究表明，在条件发生改变时，高温气冷堆模拟机系统的复杂度有非常明显的变化，且不同条件下，对于系统复杂性影响显著的参数也不相同．此外，反应堆模拟机中各系统间耦合计算与相互反馈机理的作用，在系统的稳健度上也有很明显的体现．这些成果表明，复杂性分析方法在系统状态监测和危机预警领域可以发挥重要的作用．

Abstract: Complexity-based pattern recognition and diagnosis for engineering simulation system of HTR-PM are carried through analyzing 12 state parameters of the nuclear reactor. It is shown that the complexities and robustnesses of HTR-PM simulation system are remarkably discrepant in three different operating modes （normal operation, increased ambient temperature and sudden leakage in primary loop）. The effectivenesses of coupling calculations and feedback of multi systems of the HTR-PM simulator are also embodied in system robustness. All these results demonstrate that the method of complexity and robustness can indicate the availability of different parameters for recognizing and diagnosing the operating conditions of the HTR-PM.
