A Boiler Control System Based on PLC and WINCC

Use the practical boiler as research object in this paper,an industrial boiler control system is de- signed.The system includes the upper supervisory(US)and lower computer (LC).PROFIBUS network con- nect US and LC.The paper combine PLC,Configure software with industrial control computer,advanced com- puter control replaced the traditional control,feed water、combustion、minus pressure of hearth and the pressure of the steam automatic control are realized,and get better control accuracy.
