Patent ID: 8312703

Claim:
A solar-thermal gas turbine generator comprising: a solar-thermal gas turbine equipped with a compressor that takes in a compressible working fluid to raise a pressure thereof, a heat receiver that raises a temperature of the compressed working fluid by heating the working fluid with heat of sunlight collected by a light collector, and a turbine that converts heat energy held by a high-temperature, high-pressure compressible working fluid into mechanical energy; a generator that is driven by the solar-thermal gas turbine to generate power; and a steam power generation cycle in which the high-temperature compressible working fluid exhausted from the turbine is introduced into a steam generator, and in which a steam turbine that is operated by steam generated at the steam generator drives the generator to generate power, wherein a solar-thermal steam generator that generates steam by being heated with heat collected by the light collector is provided upstream of the steam turbine of the steam power generation cycle, and wherein the light collector is adjustable in accordance with sunlight intensity, and the light collector adjusts a distribution ratio for distributing the sunlight collected by the light collector to the heat receiver and the solar-thermal steam generator.
