摘要

提出一种新的太阳能聚光器概念设计——固定反光板抛物面聚光器,它由一个固定放置的、采用非对称抛物面线形的反光板和一个可移动的接收器组成。与传统的线性聚光器（槽式和线性菲涅尔式）相比,具有转动部件少、建造成本低、土地利用率高等优点。首先通过光学模拟和实验研究偏离角与聚光特性之间的关系,然后通过建立数学模型研究偏离角的分布特性。结果表明：对于不同地理位置,当该聚光器采用东西轴向放置、抛物线倾角设为当地纬度时,聚光斑最小且整体聚光比达到8~22,初步验证了该聚光器在不同时间和位置条件下进行太阳能聚光的可行性。

Abstract

This paper presents a novel conceptual design of solar concentrator, the fixed reflector parabolic concentrator, which consists of a fixed reflector with an asymmetric parabolic profile and a movable receiver. Compared with traditional linear concentrators （parabolic trough and linear Fresnel）, it offers the advantages of fewer moving parts, lower construction cost and higher land utilization rate. Firstly, the relationship between the deviation angle and the concentration characteristics was studied through optical simulation and experiments. Then, the distribution characteristics of the deviation angle were investigated by establishing a mathematical model. The results show that for different geographical locations, when the concentrator is placed in the east-west axis direction and the parabolic inclination angle is set to the local latitude, the focal spot is the smallest and the overall concentration ratio ranges from 8 to 22. This paper provides an initial validation of the feasibility of the novel linear solar concentrator for solar concentration under varying temporal and positional conditions.
