Solar thermal gas turbine system

An object of the present invention, in a gas turbine for water spray to the intake of the compressor is to provide a solar gas turbine system that reduces the influence of disturbance, such as weather conditions. Solar gas turbine system of the present invention has a compressor for compressing air, a combustor for burning a fuel air compressed by the compressor, and a turbine driven by combustion gas generated by the combustor a gas turbine 200, a condenser heat heat collector 130 to solar heat and the heat storage device 140 to reserve a high-pressure hot water generated by the solar heat hot collecting in said population thermal device, the high pressure air to the suction by the compressor a spraying device 170 for spraying hot water, and an intercooler 180 for mixing the high pressure hot water to the compressed air bled from the compressor as cooling air into the turbine, the steam generated with the high-pressure hot water as a heat source to the combustor characterized by comprising a supplying evaporator 190.
