Title:
HELIOSTAT CONCENTRATING PHOTOVOLTAIC GENERATOR AND POSITIONING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/042136
Kind Code:
A1
Abstract:
A positioning method for a heliostat concentrating photovoltaic generator, comprising: arrange a day shaft (3) of a heliostat concentrating photovoltaic generator to be parallel to the earth's axis of rotation and a season shaft (4) to be perpendicular to the day shaft (3), and adjusting the day shaft (3) and the season shaft (4) to make a photovoltaic assembly (1) face the sun; with the rotation of the earth, a reducer and a stepper motor drive the day shaft (3) to rotate, and the day shaft (3) drives the photovoltaic assembly (1) to rotate, the rotation cycle being 24 hours; and with the revolution of the earth, the relative position of the earth relative to the sun changes, the day shaft (3) drives the season shaft (4) to rotate by means of a gear group, and the season shaft (4) rotates correspondingly in accordance with the sine rule to make the photovoltaic assembly (1) always perpendicularly face the sun. The method can implement accurate positioning, points to a set position, and effectively solves the positioning problem of a photovoltaic assembly (1) in photovoltaic power generation.
