Main steam whose flow rate is controlled through a steam control valve on the main steam line is supplied to the inlet of the steam turbine, while the steam condition is controlled through a stop valve on the process steam line. In a multi-stage mixed-pressure steam turbine configured to supply different process steams to an intermediate stage of the steam turbine; the stop plate has a valve body that is spring loaded in a valve closing direction by a spring force of a closing spring;
A pressure oil supply line is connected to the side that opposes this spring force, a three-way switching valve is installed on this pressure oil supply line, and the stop valve is turned off in the region where the opening degree of the main steam control valve is larger than the set opening degree. When the main steam control valve is moved in the opening direction, on the other hand, in a region where the opening degree of the main steam control valve is smaller than the set opening degree, the steam three-way switching valve is switched to the drain side and the stop valve is closed. Control device for mixed pressure steam turbine. 2. A relay trip valve is installed on the pressure oil supply pipe between the stop valve and the three-way switching valve, and the stop valve is closed by switching the relay trip valve to the drain side when tripping or when the load is interrupted. A control device for a multi-stage mixed pressure steam turbine according to claim 1, characterized in that:
