PURPOSE:To maintain continuously adequate wetness for the turbine load variation of the titled turbine by a method wherein the discharging steam pressure for the optimum wetness is calculated, and the amount of discharging steam pressure of the turbine is controlled to be coincident with said calculated amount by adjusting the amount of cooling water of a steam condenser or the amount of ejector steal. CONSTITUTION:A number of revolutions N of a steam condensing turbine 1, a pressure P of a inlet steam A, a temperature T, an condensate flow G, and a condensate upper pressure V are continuously measured, those data are inputted to a computer 3, then the optimum discharging pressure is obtained according to the inputted data by following prestored algorism. The optimum discharging pressure signal is outputted from the computer, then a steam F for an air ejector 5 of a cooling water C for a steam condenser 4 are automatically adjusted as the upper pressure V of the steam condenser is controlled by using said optimum signal value as the setting value of said pressure. |
