Zoning evaluation of freeze-thaw erosion intensity of large photovoltaic power plant sites in high-altitude and cold area
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.
