Coordinated Control System Of 300MW CFBB

CFBB (Circulating Fluidized Bed Boiler) has many advantages, such as little pollution to the environment, strong fuel adaptability, high boiler thermal efficiency and so on. CFBB becomes one of the best chosen technology for power plant and thermoelectric plant, it's proved reliable clean coal burning technology and people regard it. The technological flow and coordinated control system of CFBB are introduced here, then simplify the turbine-generator unit as a two input and two output's control plant, and a dynamic math model of the Coordinated Control System is set up by some reasonable hypothesis. Then Neural PID is used to control System. Compared with the traditional PID controller, better control performance can achieve by this intelligent control algorithm.
