Abstract

The utility model discloses an accurate and automatic tracking system for the photovoltaic (PV) panel of a solar power plant. By means of the combination of a photoptometer, an electronic compass TCM and an angle calibrator RDC module, the pitch angle and the azimuth of a PV panel tracking system, the variation of the sunlight vertical illumination angle of a PV panel, and the maximum value of a directional diagram, can be measured. Meanwhile, the automatic tracking is realized by means of the internal closed-loop system of a computer. The variable quantities of both the pitch angle and the azimuth of the PV panel automatic tracking system can be measured by means of the electronic compass TCM. By means of the photoptometer, the strength of the sunlight can be measured. By means of the angle calibrator RDC module, the angle calibration is carried out. Through the processing step of the computer, the PV panel is driven to rotate by means of a servo drive system. In this way, the plane of the PV panel is always facing the sun during the rotation process, so that the normal operation of the solar power plant is ensured. The accurate and automatic tracking system for the photovoltaic panel of the solar power plant is designed for civil use and is economical and practical. Due to the adoption of the angle calibrator RDC module, the usage effect is ensured to be good, while the production cost is lowered. Meanwhile, the system is easy in popularization, wherein errors generated during the rotation process can be corrected just in time. Based on the accuracy principle, the automatic and continuous tracking of the system is realized. Meanwhile, the power generating capacity of the PV panel is increased to be maximal.
