Abstract
A steam turbine power plant includes a life consumption amount calculator configured to calculate life consumption amounts of a turbine rotor based on a value measured by a measurer, a thermal stress limit update timing determining device configured to determine a time when thermal stress limits are updated, an accumulated life consumption amount calculator configured to calculate accumulated life consumption amounts of the turbine rotor when the thermal stress limits are updated, a planned life consumption amount setting device configured to set planned life consumption amounts of the turbine rotor based on the accumulated life consumption amounts of the turbine rotor, a thermal stress limit calculator configured to calculate and update the thermal stress limits based on the planned life consumption amounts of the turbine rotor, and a plant command value calculator configured to calculate a plant command value based on the thermal stress limits.
