Direct separation

The requirements of the solar radiation on the horizontal plane into the ramp on the solar radiation, the first solar radiation must be straight, scattered separation. According to the solar radiation observation and analysis, the ratio of the monthly average of the total daily amount of scattered radiation to the monthly average of the total solar radiation and the ratio of the total radiation on the ground plane to the monthly average of the total solar radiation on the upper atmosphere of the atmosphere is very good Correlation. Liu and Jordan obtained the regression equation for scattering radiation.

Where Kd is the ratio of the total daily amount of scattering and total radiation in the horizontal plane, KT is the ratio of the total daily mean value of the total radiation in the horizontal plane to the total solar radiation in the atmosphere,IdH is the daily IH is the monthly average of the total solar radiation on the horizontal plane (the meteorological station provides); I0 is the monthly average of the total solar radiation on the horizontal plane (provided by the meteorological station) Can be found, see Table 1-4>〕 available, into the type (1-8) to be KT, which can be IdH. Thus the level of direct radiation on the total amount of the monthly average of
