协调控制技术在核动力系统中的应用研究

在传统PID控制的基础上引入了协调控制器,以此组成核动力装置的协调控制系统.在建立核动力系统模型的基础上应用协调控制系统并进行了仿真试验,仿真结果表明:相比于传统PID控制,采用协调控制后,冷却剂平均温度和出口蒸汽压力的超调量减小,稳定时间变短,而汽轮机功率响应稍微慢了一点,但其峰值超调变小了.

Applied study of coordinate control of nuclear-power system

On the basis of traditional PID controller,coordinate controller is introduced,which formed the control system of nuclear power plant.The control system is applied to the nuclear power plant and processed simulation experiment.The simulation results show that the overshoot of the primary water's average temperature and exit steam' pressure after applying the coordinate control system is smaller than that of the traditional PID control system.The steady time is shortened,while the rise time of turbine power is a little longer.But the peaking overshoot turns smaller.
