摘 要: 定日镜作为塔式太阳能热发电系统的核心部件,主要用于跟踪太阳运动。研究以Matlab软件为仿真工具,分析并修正了一般太阳位置算法,提高了算法精度,然后建立定日镜跟踪角模型,并基于此开展太阳及定日镜运动规律的探索性研究。以中国德令哈地区为具体算例,仿真太阳在典型日的运动规律,最后以镜场正北方的定日镜为例,探讨定日镜在典型日的运动规律。研究结果可为定日镜跟踪控制器的开发、镜场布局优化设计及镜场调度的研究提供一定的基础性理论支撑。
关 键 词: 可再生能源;太阳位置;定日镜;仿真;运动规律

Abstract: As a core component of tower solar thermal power system, heliostat is mainly used to track the movement of the sun. This paper uses Matlab software as a simulation tool to analyze and modify the general sun position algorithm, which improves the accuracy of the algorithm, and establishes the heliostat tracking angle model. And based on this, the exploratory study of the sun and heliostat law of motion is carried out. The Delingha region of China is taken as an example to simulate the sun law of motion on a typical day, and the heliostat in the north of the mirror field is used as an example to discuss the heliostat law of motion on a typical day. The results provide certain basic theoretical support for the development of a heliostat tracking controller, the optimization of mirror field layout, and the research of mirror field scheduling.
Key words: renewable energy; the sun position; heliostat; simulation; law of motion
