摘要
针对太阳能光伏系统中能量转换效率低的问题,提出了在该系统中采用光线自动跟踪的方法。通过对3种光线自动跟踪的原理进行分析和对比,提出了采用光强比较法对太阳光进行自动跟踪,很好地解决了目前对光伏系统的智能化和高效率的要求。在此基础上设计了一种跟踪精度高、结构简单、控制可靠的双轴太阳光自动跟踪系统,有效地提高了太阳能的利用率。
To solve the problem of low conversion efficiency in the solar photovoltaic system, the automatic sunray- tracking is proposed in this paper. After analyzing and contrasting the principle of three kinds of automatic sunray- tracking, the light intensity comparison method is adopted to trace the sunray automatically, which can meet the demand of intelligentization and high efficiency nowadays. Therefore, the double - axis automatic sunray - tracking system, with high tracing accuracy, simple structure and reliable controllability is proposed, which helps to make full use of the solar energy.
