Solar heating

linerate.equations.solar_heating.compute_solar_heating(absorptivity, global_radiation_intensity, conductor_diameter)

Compute the solar heating experienced by the conductor.

Equation (8) on page 18 of [1] and (11) on page 4 in [4].

Parameters:

• absorptivity (Annotated[float | float64 | ndarray[Any, dtype[float64]], '']) – \(\alpha_s\). Material constant. According to [1], it starts at approximately 0.2 for new cables and reaches a constant value of approximately 0.9 after about one year.

• global_radiation_intensity (Annotated[float | float64 | ndarray[Any, dtype[float64]], 'W/m²']) – \(I_T~\left[\text{W}~\text{m}^{-2}\right]\).The global radiation intensity.

• conductor_diameter (Annotated[float | float64 | ndarray[Any, dtype[float64]], 'm']) – \(D~\left[\text{m}\right]\). Outer diameter of the conductor.

Returns:

\(P_S~\left[\text{W}~\text{m}^{-1}\right]\). The solar heating of the conductor

Return type:

Union[float, float64, ndarray[Any, dtype[float64]]]
