摘　　要：随着核电系统建模日益朝着准确化、精细化方向发展,对三维堆芯与热工水力模型耦合的研究也逐渐增多,这为控制系统的设计提供了更好的模型基础。本研究采用APROS软件对VVER-1000反应堆进行了三维堆芯与热工水力耦合建模,并设计了基于模型预测控制(MPC)的负荷跟踪控制系统和其他控制系统;随后利用稳态和瞬态仿真结果对该模型进行了验证,结果表明该模型仿真效果良好;利用三维堆芯可视化的优点,进一步验证了MPC负荷跟踪控制器的性能和安全性。这一研究不仅为核电系统研究提供了模型基础,也为先进功率控制系统的安全性分析提供了实践经验。As nuclear power system modeling increasingly moves towards greater accuracy and refinement,research on the coupling of three-dimensional core and thermal-hydraulic models has also grown,which provides a better model foundation for the design of control systems.In this study,the APROS software was used to model the coupling of a three-dimensional core and thermal hydraulics for VVER-1000.A load-following control system based on model predictive control(MPC)and other control systems were designed.The model was then verified using steady-state and transient simulation results,which showed that the model simulated effectively.Taking advantage of the three-dimensional core visualization,the performance and safety of the MPC load-following controller were further validated.This research not only provides a model foundation for studies on nuclear power systems but also offers practical experience for the safety analysis of advanced power control systems.
