摘要: 采用直流蒸汽发生器的核动力装置是一个多变量耦合的复杂被控对象,为了对其给水控制系统进行研究,设计了一个直流蒸汽发生器给水控制半实物闭环仿真系统。该系统由实时仿真系统、给水控制系统物理设备和仿真过程管理系统组成。给水控制系统物理设备采集实时仿真系统提供的参数信号,并输出控制信号至电动执行机构。半实物闭环控制仿真试验表明,该仿真系统具有较好负荷跟踪能力,可为实际直流蒸汽发生器控制系统的设计及运行提供技术指导。

Abstract: The marine nuclear power plant with Once-Through Steam Generator (OTSG) is a kind of controlled object with multi-variant and strongly coupling features.A modeling and simulating system for OTSG feedwater control is introduced in this paper.The physics equipment of control system acquires parameter signal from the real-time simulation system,and the control signal is sent to servo-actuators.The results of experiment with close-loop control on the modeling and simulating system indicate that the feedwater control system has good load tracking performance.The study would provide methodological guidance for practical design and implementation of OTSG control system.
