哈密市太阳能资源评估

Evaluation of Solar Energy Resource in Hami

摘要: 利用哈密市国家基准气候观测站1998~2017年太阳总辐射和日照时数气象资料，通过采用多种统计方法，对哈密市太阳辐射时空分布特征进行了分析，并从太阳能资源丰富度、稳定性、可利用价值、最佳利用时段等方面对哈密市太阳能资源情况进行评估。结果表明：哈密市近20 a年平均太阳辐射量为6105.47 MJ/m²，年际变化较大；平均日照时数为3424.5 h，呈显著增长趋势。总辐射和日照时数均为5月份最大，12月份最小；哈密市具有较好的太阳能资源，属于资源很丰富带；太阳能资源稳定；年日照时数大于6小时天数平均为326 d，太阳能利用价值很高；每日9~17时为最佳利用时段，全年中除了11~12月上午日照时数相对偏短之外，其它时间均为最佳利用时段。

Abstract: Based on the meteorological data of total solar radiation and sunshine duration from 1998 to 2017 from Hami National Reference Climatological Station, the temporal and spatial distribution characteristics of solar radiation in Hami are analyzed by various statistical methods, and the solar energy resources in Hami are evaluated from the aspects of solar energy resource abundance, stability, available value and optimal utilization period. The results show that the average solar radiation in Hami in the past 20 years is 6105.47 MJ/m², which varies greatly from year to year. The average sunshine duration was 3424.5 h, showing a significant growth trend. The total radiation and sunshine duration are the maximum in May and the minimum in December. Hami has good solar energy resource and belongs to abundance belt in resource. The solar energy resource is stable, the average number of daily sunshine duration more than 6 hours is 326 d, and the solar energy utilization value is very high. The best utilization period is 9~17 o’clock every day. Except for the relatively short sunshine hours in the morning of November-December, the rest time is the best utilization period throughout the year.
