针对核电厂反应堆冷却剂平均温度控制对象,采用冷却剂平均温度的非参数模型,设计动态矩阵控制器(DMC)。采用用于过程控制的对象连接与嵌入(OPC)技术与核电仿真模型连接,构建用于冷却剂平均温度控制仿真研究的平台,在矩阵实验室(MATLAB)环境下针对小范围负荷波动设计动态矩阵预测控制器。仿真得到冷却剂平均温度的跟踪曲线与冷却剂平均温度调节棒(R棒)的变化曲线。通过堆芯轴向功率分布偏差,验证该预测控制算法在满足优化控制性能的同时,保证了反应堆功率分布的安全合理性。
Aiming at the average reactor coolant temperature control object in nuclear power plant, the dynamic matrix controller (DMC) is designed by adopting the non-parametric model of coolant average temperature. The object connection and embedding (OPC) technology for process control and the nuclear power simulation model are connected to build a platform for the simulation research of coolant average temperature control. The dynamic matrix is designed for small-scale load fluctuation under the condition of matrix laboratory (MATLAB) Predictive controller. The simulation curve of the average temperature of the coolant and the average temperature of the coolant rod (R rod) curve. Through the deviation of core axial power distribution, it is verified that this predictive control algorithm can meet the optimal control performance while ensuring the safety and rationality of reactor power distribution.
