该文基于对菲涅尔定向装置的研究,搭建其集热性能测试实验平台,并采用TracePro光学模拟软件,建立菲涅尔定向光输运装置的光学模型。在进行模型验证后,模拟分析跟踪误差和安装误差对光学效率的影响。研究结果表明：俯仰角、旋转角的跟踪误差会导致菲涅尔定向光输运装置光学效率的降低,并且俯仰电机误差范围应控制在±0.1°,方位电机误差范围应控制在±0.5°;当菲涅尔定向光输运装置中定向光输运器抛物反射面的焦点与菲涅尔透镜的聚光焦点存在安装误差时,菲涅尔定向光输运装置光学效率普遍下降,最大偏移量不宜超过0.1。但当偏移量不超过0.5时,将定向光输运器向下侧偏移或将菲涅尔透镜向上偏移,有利于提高菲涅尔定向光输运装置（LTF-SC）光学效率。该研究结果为菲涅尔定向光输运装置和菲涅尔中央接收式太阳能高温集热系统领域的研究和应用提供参考。
Abstract
This paper built an experimental platform of the Fresnel directional light-transmitting device and carried out the research of its heat collection performance. The topic model of the Fresnel directional light-transmitting device was established by using theTracePro optical simulation software to establish the optical model of the Fresnel directional light-transmitting device. After model validation, the effects of tracking error and installation error on optical efficiency were simulated and analyzed. The research results show that the tracking errors of the pitch angle and rotation angle will lead to the reduction of the optical efficiency of the Fresnel directional light transmission device. The error range of the pitch motor should be controlled within ±0.1°, and the error range of the azimuth motor should be controlled within ±0.5°. When there is an installation error between the focal point of the parabolic reflection surface of the directional light transmitter and the focus of the Fresnel lens, the optical efficiency of the Fresnel directional light transmission device generally decreases, and the maximum offset should not exceed 0.1. However, when the offset does not exceed 0.5, the directional light transmitter is shifted downward or the Fresnel lens is shifted upward, which is beneficial to improve the optical efficiency of the orientated light transmitting Fresnel lens solar concentrator （LTF-SC）. The results of this study provide a reference for the research and application of the Fresnel directional light transmission device and the Fresnel central receiving high temperature heat collection system.
