v_wind_hub
(weather, data_height)[source]¶ Calculates the wind speed at hub height.
The method specified by the parameter wind_model is used.
Parameters: - weather (DataFrame or Dictionary) – Containing columns or keys with the timeseries for wind speed v_wind in m/s and roughness length z0 in m, as well as optionally wind speed v_wind_2 in m/s at different height for interpolation.
- data_height (DataFrame or Dictionary) – Containing columns or keys with the heights in m for which the corresponding parameters in weather apply.
Returns: v_wind – Wind speed in m/s at hub height.
Return type: pandas.Series or array
