1. A startup control device comprising:
a determination unit that, for a predetermined physical quantity that constrains startup of a power generation plant, determines, based on a predicted value of the physical quantity according to an elapsed time from the startup when the power generation plant is started based on a predetermined optimal startup schedule, and an observed value of the physical quantity acquired during the startup of the power generation plant, whether or not the observed value exceeds the predicted value;
a speed adjustment unit that, when the determination unit determines that the observed value exceeds the predicted value, issues an instruction to decrease a progress speed of the elapsed time from the startup in the optimal startup schedule;
a startup timer that advances the elapsed time from the startup at a speed based on the instruction; and
a control unit that outputs, to the power generation plant, a control signal corresponding to a target output according to the predetermined optimal startup schedule at a time corresponding to the elapsed time indicated by the startup timer.
