Abstract

The study is aimed at developing a solar power plant module based on flat Fresnel mirrors for use in autonomous solar installations of sufficient capacity in order for individual consumers to obtain thermal, mechanical, or electrical energy. A simpler design technology of manufacturing a composite compact linear Fresnel mirror concentrating system (LFMCS) is presented. A module of a solar installation consisting of an LFMCS with linear flat elements of optimal size, coordinated with the optimal size of the receiver that is installed in the focal zone and converts the energy of concentrated solar radiation flows to thermal energy to generate high-pressure steam. A distinct feature of the new design is that it uses a number of optimally sized linear flat mirrors. The approach to determining the optimal dimensions of flat mirrors is validated. These mirrors are used instead of their parabolic counterparts. The simplest technology of manufacturing a concentrator is proposed. That said, the task of making the radiant flux denser for a more efficient conversion of solar energy to electricity is fulfilled by coordinating the optimal receiver size with the optimal size of flat elements. The specific optimal sizes of linear elements of a 10 × 10 m² LFMCS are determined by optical-geometric modeling with regard to the optimal size of the receiver located in the focal zone. The optimal process solutions for manufacturing a 10 × 10 m² LFMCS design with a receiver of d_opt = 0.11 m are established that have the highest efficiency at L_opt = 0.072 m of the unified linear elements of the LFMCS.

开发复合线性菲涅耳镜聚光系统的设计

摘要

该研究旨在开发一种基于平面菲涅耳镜的太阳能发电厂模块，该模块可用于容量足够大的自治太阳能设备中，以使各个消费者获得热能，机械能或电能。提出了一种制造复合紧凑型线性菲涅耳镜聚光系统（LFMCS）的更简单的设计技术。太阳能装置的模块，由具有线性尺寸最佳尺寸的线性平面元件的LFMCS组成，与安装在焦点区域中的接收器的最佳尺寸相协调，并将集中的太阳辐射流的能量转换为热能以产生高压蒸汽。新设计的显着特征是它使用了许多最佳尺寸的线性平面镜。确定平面镜最佳尺寸的方法已得到验证。这些反射镜代替了抛物面反射镜。提出了制造浓缩器的最简单技术。就是说，通过使最佳接收器尺寸与平面元件的最佳尺寸相协调，可以实现使辐射通量密度更高以更有效地将太阳能转换为电能的任务。线性元件的特定最佳尺寸为10×10 m² LFMCS是通过光学几何建模来确定位于焦点区域中接收器的最佳尺寸的。建立了用于制造接收器为d _opt = 0.11 m的10×10 m ² LFMCS设计的最佳过程解决方案，该解决方案在L FMCS的统一线性元件中L _opt = 0.072 m时具有最高效率。
