1. An activation control device for a steam turbine plant, the steam turbine plant includinga heat source device configured to heat a low-temperature fluid using a heat source medium to generate a high-temperature fluid,a steam generator for generating steam by thermal exchange with the high-temperature fluid,a steam turbine to be driven by the steam, andan adjuster for adjusting a plant operation amount,the activation control device comprising:

  • a predicting unit for calculating a predicted value for at least one constraint to be used to control the activation of the steam turbine;

    an activation control parameter setting unit configured to calculate, based on an initial value of a plant state amount, an activation control parameter to be used to control the activation of the steam turbine; and

    a plant operation amount calculator configured to determine the plant operation amount, based on the predicted value for a constraint, the predicted value being calculated by the predicting unit, and on the activation control parameter calculated by the activation control parameter setting unit, so that the constraint does not exceed a predetermined limit.
