PROBLEM TO BE SOLVED: To solve the problem that a conventional control requires to acquire a steam flow rate characteristic by combination of valves not to be tested when controlling a valve on the basis of a steam flow rate characteristic formed by combining flow rates of valves other than a test valve. SOLUTION: A turbine control device for controlling a control valve by converting a demand flow rate signal from a flow rate command section into opening signals of a plurality of control valves for adjusting a fluid flow of one turbine, is equipped with functions for calculating a flow rate flowing in the turbine on the basis of openings of one valve to be tested and the other control valves, for calculating a correction amount with respect to a fluctuation portion of the test valve based on the calculated flow rate and for adding the correction amount to the demand flow rate signal during executing a valve test of one of the control valves.
