A single-shaft combined plant having an emergency shut-off oil system is provided, The emergency shut-off oil system is constituted such that when a steam governing valve tripping electromagnetic valve is opened, only a steam turbine is stopped; a master tripping electromagnetic valve is connected to a fuel gas control valve emergency shut-off oil line, a fuel oil control valve emergency shut-off oil line, and a steam governing valve emergency shut-off oil line via check valves; and when the master tripping electromagnetic valve is opened, both the steam turbine and a gas turbine are stopped. Thus, only the steam turbine can be stopped. Even if a tripping valve provided on the fuel gas control valve emergency shut-off oil line or the fuel oil control valve emergency shut-off oil line does not open because of a breakdown, the gas turbine can be stopped reliably.
