<p>Provided are a gas turbine electricity generation device, and an operating method therefor, with which the output can be improved by spraying heated water obtained with the heat energy of solar heat, and with which stable operation can be obtained. This gas turbine electricity generation device (S) is equipped with: a compressor (2) that compresses air; a combustor (4) that burns a fuel and compressed air from the compressor (2); a gas turbine (1) that is driven by the combustion gas from the combustor (4); an electricity generation device (3) that is connected to the gas turbine (1) via a shaft (1j), and that is driven by the rotation of the gas turbine (1); a heat exchanger (705) that exchanges heat with a heat medium (w2) that has been heated using solar heat; heat storage tanks (703, 704) that store the heat medium (w2); a first bypass line (b3) that bypasses a circulation path that is on the to-be-heated side and is formed with the heat exchanger (705); a first adjustment valve (717) that adjusts the flow volume of the first bypass line (b3); and a suction air cooling chamber (5) for spraying into the air in the compressor (2), by means of spray nozzles (6), heated water (w4) that has been heated by the heat exchanger (705).</p> |
