SOLAR THERMAL POWER GENERATION FACILITY AND METHOD OF STARTING UP SAME

摘要

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).

主权项

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 generates electricity by rotation of the turbine rotor; a start-up device which rotates the turbine rotor at the 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 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.
