21世紀初,能源消耗和环境污染问题对世界各国经济发展的影响愈加严重,开发新能源来替代传统的化石能源受到了空前的关注。太阳能被认为是无限能源,是目前较为理想的可替代能源。光伏发电系统由太阳能电池、蓄电池、控制器和逆变器组成,可以将太阳光能转换成电能,实现太阳能的有效利用[1]。
1 我国跟踪式光伏发电发展现状
为了促进能源的节约利用和环境的良性保护,我国于20世纪末期开始太阳能光伏发电技术的研发。传统的太阳能光伏发电以固定式发电系统为主,但固定式光伏发电系统存在受光能力差、发电效率低以及影响生态环境等弊端。为了提高光伏发电产能,跟踪式光伏发电系统逐渐代替了固定式光伏发电系统的应用,它与固定式发电设备相比,发电系统的受光能力得到大幅度上升,可有效提高发电量30 %左右[2]。……
