制御装置。In a steam turbine equipped with a high-pressure bypass that bypasses the high-pressure turbine and flows steam from the boiler main steam line to the low-temperature reheat line, the water is cooled in the middle of the cooling water piping by branching from the boiler feed water pump and reaching the cooling water regulating valve. In addition to installing a water valve, a temperature detector is installed downstream of the high-pressure steam check valve to detect the steam temperature of the low-temperature reheating pipe, and the output of this temperature detector is compared with a preset value. A control device for a steam turbine, characterized in that the control device for a steam turbine is configured to close the cooling water main valve by operating an operation setting device based on an output from a calculation device.
