Claim Text:
1. A solar thermal power generation facility comprising: a compressor which compresses a working medium, thereby producing a compressed medium; a heat receiver which receives sunlight, thereby heating the compressed medium; a turbine in which a turbine rotor is rotated by the compressed medium heated in the heat receiver; a power generator which generales electricity by rotation of the turbine rotor; a start-up device which rotates the turbine rotor at a time of start-up; bypass means for making at least a portion of the compressed medium from the compressor bypass the turbine or the heat receiver; and a control device which controls rotational torque of the turbine rotor by making the compressed medium bypass the turbine or the heat receiver by the bypass means before a rotor rotational speed reaches a rated rotational speed in a speeding-up process of the rotor rotational speed by the start-up device and adjusting a flow rate of the compressed medium which is made to bypass the turbine or the heat receiver, wherein the control device makes the compressed medium not bypass the turbine or the heat receiver by the bypass means before the rotor rotational speed reaches a predetermined rotor rotational speed that is lower than the rated rotational speed in the speeding-up process, and makes the compressed medium bypass the turbine or the heat receiver after the rotor rotational speed reaches the predetermined rotor rotational speed, and wherein the control device instantaneously reduces the flow rate of the compressed medium which is made to bypass the turbine or the heat receiver by the bypass means, at a time of incorporation in which the power generator is connected to an electric power system after the rotor rotational speed reaches the rated rotational speed.
