湖南安乡县太阳能资源分布特征及初步评估

Abstract

根据中国气象局发布的气象行业标准《太阳能资源评估方法QX/T89-2008》，基于多年长沙气象站的太阳总辐射、武汉气象站的直接辐射以及安乡气象站的日照时数资料，对湖南省安乡县1962~2015年太阳能资源分布特征进行了分析，并对该地区的太阳能资源进行了评估。结果表明：安乡地区年太阳总辐射量和直接辐射量呈减少的趋势，太阳散射辐射量呈增加的趋势，且三者均表现为夏季最多，春秋次之，冬季最少；对该地区太阳能资源的评估表明，安乡县属于太阳能资源丰富地区，且太阳能资源较稳定，其太阳能资源可利用平均天数为166.3天。 According to the solar resource assessment methods released by China Meteorological Adminis-tration, many years of the total solar radiation data about Changsha meteorological station, the direct radiation data about Wuhan station and the sunshine hours data about Anxiang station, this study analyzed the distribution and the richness, stability and availability of solar energy resources in Anxiang County of Hunan Province since 1962 to 2015. The results showed that, the overall annual total solar radiation and direct solar radiation in Anxiang tended to decrease since 1962, the diffuse radiation tended to increase. The quantity of radiation is the most in summer, the second in spring and autumn, and the least in winter. The assessment of solar energy resources in this region shows that Anxiang County is a rich area of solar energy resources, and solar energy resources are more stable. The average available days of solar energy resources are 166.3 days in this region.
