The key technology of the dish-type solar thermal power generation tracking control system is to make the solar light always illuminate vertically on the dish concentrator to improve the utilization of solar energy. The purpose of the dish concentrator to track the moon is to measure the relative energy density distribution of the moonlight"s spotlight spot, multiply by DNI to obtain the energy flow density distribution of the sun"s spotlight spot. The astronomical algorithm is used to calculate the elevation and azimuth of the sun and the moon, resulting in high-precision sun and lunar positions. The experimental platform breaks through the traditional control method, and uses the new upper computer software dishcontrol.exe to control the pitch and horizontal drive mechanism of the dish concentrator to track the altitude and azimuth of the sun and the moon. The tracking mode is two-axis tracking mode. The tracking accuracy of the system can reach 0.001 radians, and the tracking accuracy is doubled.
