Abstract

The present invention discloses a thermal-current generating system by complementing geothermal energy and solar energy, including a chimney, a turbine generator arranged at the bottom of the chimney and a heat collecting shelter for collecting solar energy arranged below the chimney. The present invention is characterized in that the inside of the heat collecting shelter is provided with a coiled radiator; the coiled radiator is respectively connected with a first geothermal well, a regenerative tank and a second geothermal well through a pipeline and a valve. The system effectively solves the operating continuity and the stability of the solar thermal-current power station, improves the peak load capacity of the power station and provides guarantee for the interconnected synchronous generation.

Description

technical field [0001] The present invention relates to a solar power generation system, and also relates to a geothermal power generation system, specifically a system that utilizes solar energy and geothermal energy to heat to generate temperature differences and generate pressure differences under chimney suction to generate electricity. Background technique [0002] Solar thermal power plants began in the late 1970s, and after nearly 30 years of development, a certain technical foundation has been formed. However, solar thermal power plants are constrained by weather changes and day and night alternation, with unstable operation, poor continuity, and low peak-shaving capabilities, making it difficult to realize grid-connected power generation. So far, some scholars have proposed to improve the heat storage medium to improve the stability of the system operation. This improvement measure can only deal with the short-term absence of the sun, and the effect is not ideal. ...
