Posture adjustment control system for solar photovoltaic module

Abstract

The invention provides an attitude adjustment control system for a solar photovoltaic module, which comprises a bearing bracket, a pitch angle regulating motor, a driving circuit, a control device, a cassette, a Fresnel lens array, a secondary condensing mirror and a filter, wherein the cassette, the Fresnel lens array, the secondary condensing mirror and the filter are fixed on the bearing bracket; the secondary condensing mirror is positioned in front of a focus of the Fresnel lens array; the top surface of the cassette is provided with a through hole; the filter is embedded in the through hole; the cassette comprises a semitransparent film arranged below the through hole and a camera arranged below the semitransparent film; the camera is connected with the control device; and the filter is positioned in front of a focus of the secondary condensing mirror. In the invention, light at each horizontal azimuthal angle is collected by the Fresnel lens array, and then the pitch angle regulating motor is controlled to regulate the azimuth of a pitch angle by the position of a facula in the cassette, so that the two-dimensional tracking on the sun is simplified into the one-dimensional tracking, the complexities of the mechanical structure and the control on the azimuthal angle are greatly reduced, and the sun tracking precision is improved.

Description

technical field [0001] The invention relates to a solar photovoltaic system, in particular to a control system for attitude adjustment of a solar photovoltaic module. Background technique [0002] The solar tracking system is a power device that keeps the solar panel facing the sun at any time and allows the sunlight to illuminate the solar panel vertically at any time, which can significantly improve the power generation efficiency of the solar photovoltaic module. Due to the rotation of the earth, compared with a solar photovoltaic power generation system at a fixed location, the sun rises and sets every day in spring, summer, autumn and winter. The sun, the power generation efficiency will reach the best state. At present, the general solar tracking system in the world needs to calculate the angle of the sun at different times of each day of the year according to the longitude and latitude of the placement point, and store the sun position at each time of the year to PLC...
