【Abstract】 In view of the defects with traditional sun azimuth automatic tracking system,for instance,system structure is complicated,tracking precision is lower and tracking time is longer,the paper adopts a new type of sun azimuth tracking system. The new type sun azimuth automatic tracking system includes two parts of the solar azimuth initial tracking system and the solar azimuth accurate tracking system. Among them,the sun azimuth initial track system calculates current time sun azimuth by data acquisition unit,and then uses the controller drive motor to track the sun azimuth; the sun azimuth accurate track system searches for current time sun azimuth by light measurement device,and then uses the controller drive motor to track the sun azimuth. The new type sun azimuth automatic tracking system can search for the sun azimuth fastly with high precision,therefore the utilization efficiency of the photovoltaic power plant is improved.更多还原
