摘　　要：随着国内土地政策收紧与光伏电站用地环境日益紧张,复杂地形成为光伏电站建设的主要用地条件。笔者以广西贵港市某光伏电站项目为依托,深入探讨复杂地形条件下光伏电站建设策略。通过分析场地特点,设计多种支架形式与光伏组串方案,包括固定式支架、平单轴跟踪式支架及1/2、1/4等不同规格的组串排列方式。通过Canela3D软件模拟日照环境,验证各方案的阴影遮挡情况,确保组件不受遮挡。研究结果表明,最优方案的装机容量和年上网电量较其余两方案分别提升15.3%和12.8%,土地利用率则分别提升4.4%和3.4%。该研究为复杂地形下的光伏电站建设提供了科学依据,有助于在有限土地资源上实现更高的发电效率和经济效益。With the tightening of domestic land policies and increasingly constrained land availability for photovoltaic plants,complex terrains have become the primary site conditions for photovoltaic project construction.Taking a photovoltaic plant project in Guigang City,Guangxi Zhuang Autonomous Region as a case study,this paper conducts an in-depth exploration of construction strategies for photovoltaic plants under complex terrain conditions.By analyzing site characteristics,multiple support structures and PV string layout schemes were designed,including fixed mounting structures,horizontal single-axis tracking systems,and string configurations such as half-cell and quarter-cell arrangements.The Canela3D software was employed to simulate solar irradiance conditions and validate shading effects across different schemes,ensuring unobstructed module performance.The results show that the installed capacity and annual to-grid energy of the optimal scheme are increased by 15.3%and 12.8%,respectively,compared with the other two schemes,and the land utilization rate is increased by 4.4%and 4.3%,respectively.This study provides scientific guidance for photovoltaic plant construction in complex terrains,facilitating higher power generation efficiency and economic benefits under limited land resources.
