Abstract
A steam turbine plant includes: a superheater; a reheater; a high-pressure turbine; an intermediate-pressure turbine; a low-pressure turbine; a condenser; a bypass pipe that branches off a main steam pipe and includes a high-pressure turbine bypass valve; a bypass pipe that branches off a high-temperature reheat steam pipe, is connected to the condenser, and includes a low-pressure turbine bypass valve; and a branch pipe that branches off a low-temperature reheat steam pipe, is connected to the condenser, and includes a ventilator valve. At the time of turbine start up, the ventilator valve, the high-pressure turbine bypass valve, and the low-pressure turbine bypass valve are fully opened to allow steam to be circulated simultaneously into the high-pressure turbine and the intermediate-pressure turbine.
