摘要： Anonlinear dynamic simulation model based on coordinated control of speed and flow rate for the molten salt reactor and combined cycle systems is proposed hereto ensure the coordination and stability between the molten salt reactor and power system. This model considersthe impact of thermal properties of fluid variation on accuracy and has been validated with Simulink. This study reveals the capability of the control system to compensate for anomalous situations and maintain shaft stability in the event of perturbations occurring in high-temperature molten salt tank outlet parameters. Meanwhile, the control system's impact on the system's dynamic characteristicsunder molten salt disturbance is also analyzed. The results reveal that after the disturbance occurs, the controlled systembenefits from the action of the control, and the overshoot and disturbance amplitude are positively correlated while the systempower and frequency eventually return to the initial values. This simulation model provides a basis for utilizing molten salt reactors for power generation and maintaining grid stability.
