The medium and low temperature organic Rankine cycle system comprises an organic Bretton cycle heater, an organic Rankine cycle turbine, an organic Rankine cycle regenerator, a condenser and an organic working medium pump. According to the supercritical Bretton and organic Rankine combined cycle solar power generation system, the solar thermal collecting temperature and the thermal efficiency are high, in addition, the problem that solar energy time distribution is not even can be effectively solved, and meanwhile the thermal storage temperature is low.

Description

technical field [0001] The invention relates to a solar power generation system, in particular to a supercritical Brayton and organic Rankine combined cycle solar power generation system. Background technique [0002] Solar energy is an inexhaustible clean energy. Because solar thermal power generation has high theoretical thermal efficiency when collecting heat at high temperature, and it is theoretically possible to use relatively cheap heat storage energy storage to solve the problem of uneven time distribution of solar energy. problems, making solar thermal power generation more and more attention. [0003] Photothermal power generation needs to convert light energy into heat energy, and then realize thermoelectric conversion through a thermodynamic cycle. At present, among many thermodynamic cycles, the supercritical Brayton cycle is the most advantageous cycle form. New supercritical working fluids (carbon dioxide, helium and nitrous oxide, etc.) have inherent advanta...
