摘　　要：为解决光伏发电效率低、成本高等问题,本文分析了目前太阳能跟踪技术的现状和弊端,提出了一种四点式双轴光电跟踪与数据库跟踪相混合的新的跟踪技术来提高光伏发电效率的方法.光照良好时采用光电跟踪模式,光线不佳时采用数据库跟踪模式,两种跟踪模式可以自动切换,保证了跟踪的精确性,大大提高了太阳能的发电效率.这种方法成本低、效果好、精度高、易实现,可广泛应用于光伏发电系统.In order to resolve the problem of low efficiency and high cost in Solar Photovoltaic Generation,a new four-point biaxial solar tracking mode mixed with optical tracking and database tracking is presented af-ter the analysis of the research status and disadvantages for solar tracking controlling technique. The opti-cal tracking mode is at work when the light is strong,otherwise,the database tracking mode works. Au-tomatic switchover between these two modes improves the precision and generating efficiency simultane-ously. Due to the advantages of low cost,good effect,high precision and easy to achieve,this mixing tracking mode can be used extensively.
