ビン制御装置。[Claims for Utility Model Registration] (1) In a steam turbine control device that controls ground steam pressure in a steam turbine, an output detector detects that the turbine load is below a predetermined value, and A steam turbine control device, characterized in that the set pressure of the steam seal header is adjusted based on the detection signal of the steam turbine controller. (2) The adjustment device that drives the supply valve that controls the amount of auxiliary steam supplied to the steam seal header and the relief valve that controls the amount of steam released from the steam seal header is composed of an adjuster and a proportional calculator. This regulator receives a signal PSS from a pressure sensor that detects the pressure inside the steam seal header.
Utility model registration claim 1, which is configured to receive H and a signal P from a setting calculator that changes a setting value in accordance with a signal L from an output detector that detects the output of the steam turbine. The steam turbine control device described.
