单栅格型光伏步道材料结构设计与优化
Material structure design and optimization of single grid photovoltaic walkway
摘要
Abstract
To realize the integrated development of renewable energy and transportation infrastructure,a single grid photovoltaic walkway structure was proposed by taking the photovoltaic walkways under light load conditions as the research objects.The optimal structural dimensions,material parameters,and micro-photovoltaic array configuration were determined through simulation analysis,and the power generation perfor-mance was estimated.The results indicate that the critical load position of the single grid photovoltaic walk-way structure using polymethyl methacrylate(PMMA)as the transparent layer is the middle of the transverse joint.Both the concrete base width and the thickness of the transparent layer significantly impact the stress dis-tribution of the walkway slabs.Based on the optimal parameter combination derived from single-factor sensi-tivity analysis,the maximum vertical displacement and tensile stress of the transparent layer are reduced by 51.56%and 4.60%,respectively,compared with those of the original design.Through photovoltaic simula-tion,the annual power generation of the micro-photovoltaic array on photovoltaic walkway panels in Nanjing is 93.0 kW·h/m2,demonstrating that the single grid photovoltaic sidewalk has favorable power generation ben-efits and practical engineering value.关键词
