Abstract
Taking 600 MW direct air-cooling unit in Tongliao General Power Plant as the object of study
the optimal back-pressure values of the said air-cooling unit under different ambient temperatures and different operating conditions have been given
the automatic setting function of the set values in back-pressure control being realized
avoiding the influence of manual setting back-pressure upon the economic efficiency in operation of the unit.The protecting logic for anti-freeze in winter has been optimized
the whole process automation of air-cooling system being realized
enhancing the economic efficiency and safety in operation of said air-cooling unit.
