Abstract
A solar thermal power generation facility is provided with turbine bypass piping (74) which makes some of compressed air from a compressor (10) bypass a turbine (20), a turbine bypass valve (75) which adjusts the flow rate of the compressed air flowing through the turbine bypass piping (74), and a control device (80) which controls the rotational torque of a turbine rotor (21) by opening the turbine bypass valve (75) before a rotor rotational speed reaches a rated rotational speed in a speeding-up process of the rotor rotational speed by a start-up device (60) and adjusting the flow rate of the compressed air that is made to bypass, by the turbine bypass valve (75). The control device (80) instantaneously fully closes the turbine bypass valve (75) at the time of incorporation in which a power generator (50) is connected to an electric power system (S).
