Solar thermal power generation facility and method of starting up same

A method of starting up a solar thermal power generation facility that includes 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 generates electricity by rotation of the turbine rotor, and a start-up device which rotates the turbine rotor at the time of start-up, the method comprising:

• a speeding-up process of speeding up a rotational speed of the turbine rotor in the start-up device;
• and
• an incorporation procedure control process of controlling rotational torque of the turbine rotor until the time of incorporation in which the power generator is connected to an electric power system, by making at least a portion of the compressed medium from the compressor bypass the turbine or the heat receiver before the rotational speed of the turbine rotor reaches a rated rotational speed in the speeding-up process and adjusting a flow rate of the compressed medium which is made to bypass.
