| 摘 要： | 随着电网中核电装机比例的增加,核电机组必须要进行负荷跟踪。用压水堆堆芯的非线性模型,取代常用的局部线性化模型,并考虑了堆芯功率变化引起的物理和热工参数的变化,基于该模型设计了模糊自适应比例积分微分(proportion integration differentiation,PID)控制器、模糊控制器、PID控制器3种方法跟踪堆芯功率,仿真及比较分析表明,模糊自适应PID控制器,不但具有良好的动态性能,还具有更高的稳态精度。以模糊自适应PID控制为例,对负荷跟踪过程中反应堆芯内的物理过程进行了分析,结果表明,温度效应和中毒效应的负反馈,会阻碍功率跟踪的进行。

| Abstract: | With the being increased proportion of installed capacity of nuclear power units in power grid,it is inevitable to perform load following of nuclear power units.Replacing common used local linear model of the core of pressurized water reactor(PWR) by its nonlinear model and considering the variation of physical and thermal parameters caused by power variation of reactor core,three manners to trace the power of reactor core,i.e.,fuzzy adaptive proportion integration differentiation(PID) controller,fuzzy cont... |
