Abstract
In a start-up method of a single shaft combined cycle power plant, during a time period from when the gas turbine is started up to when rotation speed of the gas turbine reaches a rotation speed allowing self-sustained operation using the combustion gas, auxiliary steam from the start-up boiler is fed to the low-pressure steam turbine via the low-pressure turbine steam supply pipe by controlling valve opening degree of the auxiliary steam flow control valve. The low-pressure steam turbine generates a drive force. Speed-up control is performed in a unified manner for the gas turbine, the high-pressure steam turbine, the low-pressure steam turbine, and the power generator.
