Study On The Coordinated Control System Of The Unit Plant

In this paper, the dynamic characteristics of the unit plant are analyzed and the fundamental of the decoupling is illustrated. Then the operating principles of the four coordinated-control schemes are analyzed, among which the DEB-400 direct-energy-equivalence scheme is emphasized. The method of separating PID is used in-the fuel controller, and the parameter self-tuning intelligent control is introduced based on the product of the rate of change of the main steam pressure and the deviation of the pressure. The simulation of dynamic model shows its effectiveness.Li Liping (Thermal Power Engineering)Directed by Prof. Wang Bingshu...
