【摘要】：双轴太阳跟踪系统的轴系偏差会直接影响其跟踪太阳精度,对太阳能发电系统的整体性能具有重要影响。针对传统的高度-方位式双轴太阳跟踪系统结构,分析了跟踪系统在制造或者安装过程中可能引起的轴系偏差类型,采用矢量投影和球面几何原理建立了数学几何模型,研究了俯仰轴与方位轴正交偏差、方位轴安装垂直偏差对方位角和高度角跟踪偏差角以及太阳跟踪系统精度的影响关系;通过Matlab模拟计算得出了不同轴系偏差对双轴太阳跟踪器跟踪精度的影响变化规律。研究可为双轴太阳跟踪系统的设计、安装和提高跟踪精度提供理论依据。
[Abstract]:The shafting deviation of the biaxial solar tracking system will directly affect the tracking accuracy of the solar system and have an important impact on the overall performance of the solar power generation system. Aiming at the traditional high-azimuth biaxial solar tracking system structure, this paper analyzes the type of shaft system deviation caused by the manufacture or installation of the tracking system, and establishes a mathematical geometric model by using vector projection and spherical geometry principle. The orthogonal deviation between pitching axis and azimuth axis, the influence of vertical deviation of azimuth axis installation on azimuth and altitude angle tracking deviation angle and the precision of solar tracking system are studied. The influence of different shafting deviations on tracking accuracy of biaxial solar tracker is obtained by Matlab simulation. The research can provide theoretical basis for the design, installation and improvement of tracking accuracy of the biaxial solar tracking system.
