Abstract

The invention discloses a sterling solar power generation system capable of all-dimensionally tracking the trajectory of the sun. The trajectory of the sun is all-dimensionally tracked by tracking an hour angle and a declination angle of the sun. The system mainly comprises a main rotating mechanism, a pitch regulation mechanism and a sterling motor. Compared with the conventional mode of tracking an altitude angle and an azimuth angle of the sun, the mode of tracking the hour angle and the declination angle of the sun has the advantage that the number of rotation times of the motor is greatly decreased. A gear and rack transmission mode is adopted for the declination angle, so that the high regulation accuracy and stability of the declination angle are ensured. The system is simple in structure and high in tracking accuracy.

Description

technical field [0001] The invention relates to a Stirling solar power generation system which tracks the sun track in all directions. Background technique [0002] Stirling motors can directly convert the thermal energy generated by solar energy into electrical energy, and can directly integrate the converted electrical energy into the grid to realize the rapid grid integration of solar power generation. In recent years, due to the continuous maturity of Stirling motor technology, the solar power generation industry using Stirling motors has also gradually heated up, making solar thermal power generation gradually warming up. However, most of the current tracking methods of the Stirling solar power generation system follow the previous method of tracking the sun's altitude angle-azimuth angle to realize the tracking of the sun's trajectory. Invisibly, it has caused a waste of electric energy, especially the overall waste of electric energy in large-scale power stations is ...
