Abstract

The invention discloses a counterglow tracking method for a disc type solar thermal power generation system, comprising the following steps of: 1) acquiring solar image information, and analytically processing the solar image information by software, to obtain the position of the sun; 2) detecting the position of a spotlighting disc, and obtaining the deviation between the spotlighting disc and the sun light ray according to the position of the sun and the position of the spotlighting disc; and 3) controlling the position of the spotlighting disc of the disc type solar thermal power generation system according to the deviation, so that the light ray of the sun light is reflected by the spotlighting disc to be completely focused. The counterglow tracking method realizes the offset correction of the error according to the sequence such as obtaining the solar image information, obtaining the position of the sun and the position of the spotlighting disc, computing the deviation, controlling the action of the spotlighting disc according to the deviation, so that the accumulated error when the spotlighting disc runs can be eliminated, and the exact tracking of the sun can be realized.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a sun tracking method and a sun tracking system for a dish solar thermal power generation system. Background technique [0002] With the gradual increase in the global demand for energy, the energy structure based on fossil energy is increasingly unable to meet the requirements of sustainable development of mankind. Human beings are facing serious energy shortages and environmental pollution caused by burning fossil energy. Solar energy is a clean and renewable new energy source, and it has the advantages of huge energy, no risk of depletion, no geographical restrictions on resource distribution, high energy quality, etc., and its development prospects are very broad. Therefore, solar power generation is gradually considered as one of the most ideal new energy sources to replace thermal power generation. [0003] Dish-type concentrating solar thermal power generat...
