Abstract：Automatic control of CFB unit was based on DEB energy balance control strategy.After 100～200 t/h heating was added to the unit,the balance was broken,and the original sliding pressure curve couldn't meet the control requirements.The AGC rate and accu-racy of the unit were affected.This paper systematically studies the sliding pressure optimization control technology of the optimal valve point based on multiple working conditions to realize the self-optimization of the turbine valve point in the unit under heating conditions.This topic realized the coordination and unity of power regulation accuracy,speed and energy saving,and automatically identifies differ-ent loads and various working conditions and realized the full range of automatic collaborative optimization control.This topic deeply ex-plored the potential of energy saving,environmental protection and flexible operation of the unit,improved the indicators of the unit and enhances the core competitiveness of power generation enterprises.
