摘要:
为研究螺旋管式直流蒸汽发生器的控制仿真系统，本文基于流体质量、能量、动量守恒方程和移动边界理论，建立了螺旋式直流蒸汽发生器的动态模型。模型采用集总参数法，将螺旋管抽象成单管，沿轴向分为过冷段、两相段和过热段。以国际革新与安全反应堆(IRIS)为参考对象，进行了稳态和动态仿真实验。为了保证蒸汽出口压力恒定，用蒸汽压力偏差信号和蒸汽流量信号对二次侧给水流量进行调节，基于PID控制方法构建了蒸汽出口压力控制系统，并进行仿真验证。结果表明：建立的模型正确有效，控制系统响应良好，仿真结果符合热工水力学机理分析规律。
Abstract:
To study the control simulation system of the helical coiled once through steam generator, we developed the dynamic model based on the conservation of fluid mass, energy, momentum and moving-boundary. The lumped parameter model is handled with the single tube and is divided into three regions as subcooled, two-phase, and superheated. With the reference to International Reactor innovation and Secure (IRIS), steady-state and dynamic simulation tests were carried out in this paper. In order to keep the steam outlet pressure constant, we proposed to adjust the secondary feed water flow rate with steam pressure deviation signal and steam flow rate signal. The steam outlet pressure control system was constructed based on the PID control method and further verified by simulation. The results show that the established model is correct and effective, the response characteristics of the control system are good, and the simulation results conform to the analysis rule of thermal hydraulic mechanism.
