Abstract
In one embodiment, an exhaust chamber cooling apparatus measures output of a generator driven by a steam turbine, a temperature in an exhaust chamber of the turbine, and a pressure in a condenser that changes steam from the turbine back to water. The apparatus further outputs a first signal when it is detected that a measurement value of the output is larger than a first setting value and a measurement value of the temperature is larger than a second setting value, and a second signal when it is detected that the measurement value of the output is smaller than the first setting value and a measurement value of the pressure or a calculation value obtained from the measurement value of the pressure is larger than a third setting value. The apparatus further controls supply of a cooling fluid into the chamber, based on the first or second signal.
