摘　　要：针对传统太阳方位自动跟踪系统结构复杂、跟踪精度较低和跟踪时间较长等缺点,采用了一种新型太阳方位自动跟踪系统。该新型太阳方位自动跟踪系统包括太阳方位初步跟踪系统和太阳方位精确跟踪系统两部分。其中,太阳方位初步跟踪系统根据数据采集器计算实时的太阳方位,再运用控制器驱动电机跟踪太阳方位;太阳方位精确跟踪系统根据光照测量装置搜寻实时的太阳方位,再运用控制器驱动电机跟踪太阳方位。新型太阳方位自动跟踪系统能够快速、高精度地搜寻太阳方位,从而提高了光伏发电厂的太阳能利用效率。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 cal- culates current time sun azimuth by data acquisition unit, and then uses the controller drive motor to track the sun az- imuth ;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 photovohaic power plant is improved.
