Aiming at the problem of direct air-cooled condenser inactual operation, through the Calculation in variable working condition of air-cooled condenser, finds out the influence relations of the environment temperature, the head-on wind speed and the change of quantity discharged of the steam turbine for the back pressure of the steam turbine and standard coal loss rate of the power generation. The result shows that the difference of operation and design working conditions of air-cooled condenser is very great, user should determine in reason the operation way of air-cooled condenser in variable working condition.
