Abstract

The invention relates to a solar composite tracking method, and a solar tracking control system comprises a condenser and a control driving device, and is characterized in that the composite trackingmethod comprises the following steps: the condenser acquires the current illumination intensity; judging whether the illumination intensity is greater than a set intensity threshold value or not, If so, performing sun azimuth tracking by adopting a photoelectric tracking method; If not, carrying out sun azimuth tracking by adopting an improved sun-looking motion trail tracking method. Compared with the prior art, according to the invention, a composite solar tracking method of a photoelectric tracking method and an improved sun-looking motion trail tracking method is adopted, specific trackingmodes can be switched according to weather and illumination conditions, instability of the photoelectric tracking method can be overcome, and all-weather, high-precision and intelligent tracking of the sun position by a sun tracking control system is realized.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar compound tracking method. Background technique [0002] With the gradual increase in the penetration rate of distributed energy sources, the working efficiency of solar power generation devices has attracted more and more attention. At present, the main tracking methods of the concentrator in the solar tracking control system include the solar tracking method and the photoelectric tracking method. [0003] In the photoelectric tracking method, firstly, photosensitive elements such as photoresistors, photodiodes, and photocells are used to generate the position deviation signal of the concentrator. The position deviation signal is easily affected by environmental factors such as light, weather, and temperature, and the working stability of the sun tracking control system is affected. threaten. [0004] In the tracking method of apparent solar motion trajectory, the ...
