Abstract: The functions of AGC and the control scheme of the unit coordinative control system (CCS) were introduced. The coordinative control strategy, which is adopted in 2×300MW domestic subcritical CFB unit in Shaoguan Pingshi Power Plant for raising the AGC operation rate and optimizing the AGC adjustment quality, was provided. The practical operation shows that the month operation rate of the unit AGC is 99.3%, and the adjustment quality of the AGC can basically satisfy the requirements of the power grid; so the automation level of the whole unit was raised. 
