摘要
介绍了一种摩擦轮驱动和丝杆驱动组合的二维跟踪机构,在此基础上对跟踪可能产生的误差进行分析,并通过实践验证,得出此种驱动方案适用于各种大型光伏发电聚光器实时跟踪太阳的方位角和高度角。
The light focusing efficiency is largely influenced by the sun tracking accuracy of light focusing devices of photovoltaic generation. The potential error of one planar tracking mechanism with friction wheel and lead screw combined was analyzed. In the test, practicality indicated which can be used in real-time tracking of the elevation angle and azimuth angle of the sun for various kinds of large light focusing devices of photovohaic generation.
