广西太阳能资源评估指标体系研究与应用OA

A set of refined evaluation indicator system applicable to the characteristics of solar resource distribution in Guangxi was established by adopting the three indicators of solar resource richness,stability and direct irradiation ratio to classify solar resources.According to the actual distribution of annual total solar radiation amount in Guangxi,the indicator of solar energy resource richness was classified and refined.The C level that covered a large area of Guangxi was further refined into three sub-levels:C1,C2,and C3.The results showed that the solar energy resource richness in Guangxi was divided into five levels,of which the B-level resource-rich region was mainly located in the eastern coastal areas of Guangxi,the C1 first-level rich resources region was in south of the area near 22.5°N and along the Youjiang river valley,the C2 secondary-level rich resources region was in most areas of central Guangxi,and the C3 third-level rich resources region was concentrated in the northern area of Guangxi.The stability of solar energy resource in Guangxi was divided into two levels,of which the B-level relatively stable region was in parts of northwestern and southeastern Guangxi,and Shangsi county.The direct irradiation ratio was of C-level all over Guangxi,with more scattering radiation.
