bsrn.qc.k_index.kb_limit_test(bni, bni_extra, elevation, ghi)[source]#

Check if beam transmittance ($k_b$) stays within absolute physical limits based on elevation [1]. 根据海拔检查直射透射率 ($k_b$) 是否在绝对物理限值内。

Parameters:

  • bni (numeric or Series) – Beam normal irradiance ($B_n$). [W/m^2] 法向直接辐照度 ($B_n$)。[瓦/平方米]

  • bni_extra (numeric or Series) – Extraterrestrial beam normal irradiance ($E_{0n}$). [W/m^2] 地外法向辐照度 ($E_{0n}$)。[瓦/平方米]

  • elevation (numeric) – Site elevation. [m] 站点海拔。[米]

  • ghi (numeric or Series) – Global horizontal irradiance ($G_h$). [W/m^2] 水平总辐照度 ($G_h$)。[瓦/平方米]

Returns:

flags – Boolean flags (True = Pass). [bool] 布尔标记（True = 通过）。[布尔值]

Return type:

Series or ndarray
