摘　　要：为控制反应堆功率偏离临界程度,以某压水堆核电站为例,开展负荷跟踪反应堆功率控制方法的设计研究。根据反应性随时间的变化函数,建立核电站负荷跟踪反应性模型;在考虑阶跃变化的条件下,根据反应堆功率和反应性的动态关系,计算反应堆功率负荷动态变化;基于汽轮机负荷信号变化,进行反应堆的功率控制。实例应用实验结果表明设计的方法在反应堆功率控制的应用中展现出了良好的控制效果,不仅能够有效地控制反应堆的偏离临界程度,而且能够使其稳定地达到理想状态。To control the deviation of reactor power from the critical level,a load tracking reactor power control method was designed and studied using a pressurized water reactor nuclear power plant as an example.Establish a load tracking reactivity model for nuclear power plants based on the function of reactivity over time;when considering step changes,calculate the dynamic changes in reactor power load based on the dynamic relationship between reactor power and reactivity;control the power of the reactor based on changes in the load signal of the steam turbine.The experimental results of practical applications show that the designed method has demonstrated good control effects in the application of reactor power control.This method not only effectively controls the deviation of the reactor from the critical level,but also enables it to stably reach the ideal state.
