A startup control device for adjusting a startup schedule during startup of a power generation plant, the device includes: a determining unit which determines, on the basis of a predicted value of a physical quantity corresponding to the elapsed time from startup when the power generation plant has started up on the basis of a prescribed optimal startup schedule, and an observed value of the physical quantity acquired during the startup of the power generation plant, whether the observed value will exceed the predicted value. The device also includes a speed adjusting unit which, if the determining unit determines that the observed value will exceed the predicted value, issues an instruction to decelerate the speed of progress of elapsed time from the startup in the optimal startup schedule; and a startup timer which progresses the elapsed time from the startup at a speed based on the instruction.

Startup control device, startup control method, and program

The present invention provides a hydraulic drive train including a check valve provided in a return oil passage disposed between a branching position of a first branching oil passage and a branching position of a second branching oil passage, wherein at the time of starting of startup of the hydraulic drive train, the switching valve is closed, the opening degree of the flow rate adjusting valve is set to the initial opening degree, the on-off valve is opened, the boost pump is driven by the drive motor, and the hydraulic oil is supplied to the hydraulic pump, thereby assisting the rotational speed of the vanes by the hydraulic oil.
