云南太阳能资源时空分布特征与区划评估
SOLAR ENERGY RESOURCES SPATIO-TEMPORAL DISTRIBUTION CHARACTERISTICS AND REGIONALIZATION EVALUATION IN YUNNAN PROVINCE
【摘要】 为系统评估云南太阳能资源,在近年来完成云南清洁能源气象评估项目基础上,初步构建云南太阳能资源的精细化评估框架和模型。利用云南7个辐射站太阳总辐射资料和126个台站日照资料,建立1961—2022年全省太阳总辐射时间序列,在此基础上分析云南日照时数、日照百分率和太阳总辐射的时空分布特征。结果表明:云南太阳总辐射呈中部多,西南部次之,东部及西北部少的分布特征。云南年太阳总辐射量在905~1800 kWh/m2之间,除滇西北边缘地区外,大致呈西高东低型分布。云南太阳能资源总体可分为5个等级,滇中地区拥有云南最好的太阳能资源量,滇西南是云南太阳能资源的次高值区。云南全省年太阳能资源理论总储量约577.28×1012 kWh,太阳能资源储量总体富裕。云南大部地区具有较好的太阳能开发利用价值。
【Abstract】 The evaluation of solar energy resources is the basis and key of the development and utilization of solar energy resources.Yunnan is located in the plateau area of low latitude in our country and is one of the provinces rich in solar energy resources.In order to systematically evaluate the solar energy resources in Yunnan,based on the Yunnan clean energy meteorological assessment project completed in recent years,a refined assessment framework and model of solar energy resources in Yunnan were initially constructed.Based on the total solar radiation data of 7 radiation stations and the insolation data of 126 stations in Yunnan,the time series of total solar radiation in Yunnan from 1961 to 2015 was established.On this basis,the spatial and temporal distribution characteristics of sunshine duration,sunshine percentage and total solar radiation in Yunnan were analyzed.The results show that the total solar radiation in Yunnan is more in the central part,followed by the southwest,and less in the east and northwest.The annual total solar radiation in Yunnan ranges from 905 kWh/m2 to 1800 kWh/m2 which is generally high in the west and low in the east except in the northwest edge of Yunnan.The solar energy resources in Yunnan can be divided into five levels.The central Yunnan has the best solar energy resources,and the southwest Yunnan has the second highest solar energy resources.The theoretical total reserves of solar energy resources in Yunnan province are about 577.28×1012 kWh,and the total reserves of solar energy resources are rich.Most areas of Yunnan have good value of solar energy development and utilization.
