In order to improve the controlling quality of the coordinated control system of the unit

optimization work based on the analysis of the deficiencies in the original system control strategy on several aspects such as the main control system of boiler and steam turbine

feed water automatic regulation system

fuel master

primary air pressure adjustment

the air damper control of the coal mill was done to meet the requirements of adjustment rate and accuracy of the AGC load of the generating units. After optimization

the adaptability of boiler to the change of coal is enhanced

and the safety and stability of the unit is improved.
