High-precision sunlight tracking system and control method thereof

Abstract

The invention discloses a high-precision sunlight tracking system. The high-precision sunlight tracking system comprises a base and a supporting pillar fixed to the base. A supporting platform is fixedly arranged at the upper end of the supporting pillar. The supporting platform is provided with an azimuth angle bull gear and an azimuth angle pinion, wherein the azimuth angle bull gear and the azimuth angle pinion are mutually meshed. The azimuth angle bull gear is fixedly installed on an azimuth angle rotation shaft. An azimuth angle rotation rack is connected to the upper end of the azimuth angle rotation shaft. An elevating angle rotation shaft is horizontally arranged on the upper portion of the azimuth angle rotation rack, and penetrates through the azimuth angle rotation rack. The two ends of the elevating angle rotation shaft are each provided with a photovoltaic module. The elevating angle rotation shaft is provided with an elevating angle bull gear and an elevating angle pinion, wherein the elevating angle bull gear and the elevating angle pinion are mutually meshed. The elevating angle bull gear is fixedly installed on the elevating angle rotation shaft in a sleeving mode. An elevating angle motor is arranged on the azimuth angle rotation rack. The elevating angle motor and the elevating angle pinion are connected. An elevating angle grating ruler is installed on the side face of the azimuth angle rotation rack. The high-precision sunlight tracking system discloses a control method of the high-precision sunlight tracking system, and the control method can be used for realizing reliable high-precision tracking.

Description

technical field [0001] The invention belongs to the technical field of sunlight tracking, and relates to a sunlight tracking system applied in photovoltaic power generation, in particular to a high-precision sunlight tracking system, and also relates to a control method of the high-precision sunlight tracking system. Background technique [0002] With the improvement of people's requirements for the tracking accuracy of sunlight, people pay more and more attention to the two-dimensional tracking mechanism of the sun; among the existing two-dimensional tracking mechanisms, the mechanism for tracking the sun's altitude and azimuth is very common, and its tracking accuracy High, strong tracking ability; however, none of the existing tracking mechanisms have real-time control of the accuracy, that is, the control of the entire solar tracking system is not closed-loop, which will lead to an inevitable loss of accuracy during the tracking process.
