摘要
在全球能源枯竭问题越来越严重的情况下,太阳能作为一种可再生的绿能源在我国能源结构中的比重越来越高,光伏发电项目的发展也越来越迅速。由于传统的地面刚性光伏支架具有一定的场地限制性,近年来一种由预应力拉索体系所组成的大跨度柔性光伏支架结构正得到越来越多的应用。新系统采用悬索来承受光伏组件的负载,具有适应复杂地形条件、占地面积小、场地适应性强的特点。但由于柔性组件刚度较小、自重轻、跨度大,受风致效应明显,所以比较关键的问题是抗风设计。本文对新型柔性光伏支架结构进行概述,并总结了近年来关于柔性光伏支架的结构设计模型、风致效应等相关研究的文章,并进行总结综述,为后续研究提供参考。
In the case of more and more serious global energy depletion problems, solar energy as a kind of renewable green energy in the energy source structure of our country is higher and higher, and the development of photovoltaic power generation projects is more and more rapid. Due to the limitation of the traditional rigid ground photovoltaic support, a long-span flexible photovoltaic support structure composed of the prestressed cable system is being used more and more in recent years. The new system uses suspension cables to withstand the load of photovoltaic modules, which has the characteristics of adapting to complex terrain conditions, small footprint and strong site adaptability. However, due to the small stiffness, light weight and large span of flexible components, the wind effect is obvious, so the key problem is the wind resistance design. In this paper, the new flexible photovoltaic support structure is summarized, and the related research articles on the structural design model and wind-induced effect of the flexible photovoltaic support structure in recent years are summarized, so as to provide a reference for subsequent research.
