PROBLEM TO BE SOLVED: To provide a condenser vacuum control method of a condensate steam turbine for controlling a condenser vacuum value of the condensate steam turbine with high accuracy.;SOLUTION: A condenser vacuum control method of a condensate steam turbine controls a vacuum value of a condenser by adjusting a condenser cooling water flow rate of a steam turbine, wherein a manipulated variable of a condenser cooling water outlet motor-operated valve is acquired from a characteristic table expressing the relation between a condenser cooling water outlet motor-operated valve opening and vacuum value on the basis of a deviation between a control target vacuum value obtained from a turbine inlet steam flow rate and measured condenser vacuum value.;COPYRIGHT: (C)2008,JPO&INPIT
