摘要
当前大型光伏电场逐步向高寒高海拔地区发展,为准确评价高寒高海拔区的冻融侵蚀灾害对大型光伏电站安全运营的影响,依托高寒高海拔区某大型光伏电站工程,通过选取合适的环境因子开展研究区冻融侵蚀强度的初步计算,并耦合人类工程量化指标提出具有针对性与合理性的光伏场地冻融侵蚀强度评价模型,探讨了多环境因子和人类工程条件下的冻融侵蚀强度与其空间分布。结果表明,该光伏场址冻融侵蚀状况总体上属于中度侵蚀,其冻融侵蚀强度分布具有一定的集中性与空间分异性,且其空间分布格局主要受地形、气候和植被因素影响。同时,光伏电站的建设对场地冻融侵蚀强度具有一定的削弱作用,研究成果可为类似大型工程的冻融侵蚀评价提供参考和借鉴。
As large-scale photovoltaic power plants gradually move towards high-altitude and cold regions,accurate evaluation of the impact of freeze-thaw erosion hazards on the safe operation of photovoltaic power plants is essential.This study,based on a large-scale photovoltaic power plant in a high-altitude and cold area,conducted an initial calculation of the freeze-thaw erosion intensity in the study area by selecting appropriate environmental factors.By coupling human engineering quantitative indicators,a targeted and reasonable evaluation model for the freeze-thaw erosion intensity of photovoltaic sites was proposed,and the freeze-thaw erosion intensity and its spatial distribution under multiple environmental factors and human engineering conditions were explored.The results showed that the freeze-thaw erosion intensity of the photovoltaic site was generally moderate,with a certain degree of concentration and spatial heterogeneity in its distribution,which was mainly affected by topography,climate,and vegetation factors.Furthermore,the construction of the photovoltaic power plant had a certain weakening effect on the freeze-thaw erosion intensity of the site.The research results can provide reference and guidance for the freeze-thaw erosion evaluation of similar large-scale projects.
