A steam turbine control device according to the present invention is equipped with a first valve (5), a second valve (7), a first valve controller (25), a second valve controller (27), and a valve control adjustment unit (30). The first valve (5) is provided to a first steam supply passage (8) connected to a steam turbine (3). The second valve (7) is provided to a second steam supply passage (9) which bypasses the first valve (5) upstream along the first steam supply passage (8), and which is connected further towards the low-pressure side of the steam turbine (3) than the first steam supply passage (8). The first valve controller (25) controls the opening of the first valve (5) on the basis of flow-rate information (A) indicating the flow rate of the steam to be conveyed to the steam turbine (3). The second valve controller (27) controls the opening of the second valve (7) on the basis of the flow-rate information (A). The valve control adjustment unit (30) adjusts the opening control of the second valve (7) implemented by the second valve controller (27). |
