Abstract

The Brayton cycle energy conversion system (ECS) holds significant potential for applications in nuclear reactors, coal-fired power plants, waste heat recovery, renewable energy, and more, due to its high thermal efficiency, compact size, and small components. The system, which uses a helium-xenon (He-Xe) gas mixture as the working fluid, offers improved efficiency. However, the He-Xe Brayton cycle power generation system is characterized by strong coupling between its subsystems, along with nonlinearity, large inertia, and time-varying parameters. These factors pose significant difficulties for the system's operation and control. Therefore, it is crucial to research the modeling and dynamic analysis of the He-Xe Brayton cycle power generation system. Additionally, research into hierarchical coordinated control methods is necessary to address the system's internal characteristics and improve its performance. A mechanism model for the He-Xe Brayton cycle power generation system is established.
