系统辨识方法在HWRR反应堆动态参数估计中的应用

The Application of Dynamic System Identification Method on Reactor Dynamic Parameters Estimation for HWRR

利用动态系统辨识方法,以控制棒扰动做为堆内已知反应性输入,实现了控制微分效率、温度系数等反应堆动态参数的热态估计,并在重水型研究反应堆(HWRR)上进行了实验研究。结果是可信的,系统辨识方法能够实现反应堆某些动态参数的估计。值得指出的是,在有计算机检测或控制的反应堆上,该方法不需要增加任何设备即可应用。

Using dynamic system identification method and control rod disturbance asknown reactivity input in reactor,the hot state estimations(for control roddifferential efficiencies,temperature coefficent,etc)have been realized.Expe-riments have been done at the HWRR.The results are reliable and the dynamicsystem identification method can be used for the estimation of some reactordynamic parameters.It should be pointed out that this method may be used wi-thout any additional equipment if there is a computer sense or control on rea-ctor.
