In the control of feedwater to the steam generator in a power plant comprising one steam generator and a plurality of turbine plants, the water level in the steam generator and the flow rate balance between the steam flow rate and the feedwater flow rate of each turbine plant will be stabilized. In the power plant comprising one steam generator and a plurality of turbine plants combined, the control in the feedwater controller of the first turbine plant (main turbine plant) is normal control, that is, to control the feedwater control valve through the use of detection signals from the steam generator level detecting unit, the main steam flow detecting unit and the feedwater flow detecting unit of the first turbine plant, and the control in the feedwater controller of the second turbine plant (duplicate turbine plant) is to control the feedwater control valve through the use of a detection signal from the condenser level detecting unit of the first turbine plant.
