reskit.wind.core.design_turbine.onshore_turbine_from_avg_wind_speed(wind_speed, constant_rotor_diam=None, base_capacity=None, base_hub_height=None, base_rotor_diam=None, reference_wind_speed=None, min_tip_height=None, min_specific_power=None, max_hub_height=None, tech_year=2050, baseline_turbine_fp=None)#

Suggest onshore turbine design characteristics (capacity, hub height, rotor diameter, specific power) for a 2050 European context based on an average wind speed value. The default values and the function’s normalization correspond to the baseline turbine design considered by Ryberg et al. [1] for a wind speed equal to 6.7 m/s. See notes.

Parameters:

  • wind_speed (numeric or array_like) – Local average wind speed close to or at the hub height.

  • constant_rotor_diam (bool, optional) – Whether the rotor diameter is maintained constant or not, by default True

  • base_capacity (numeric or array_like, optional) – Baseline turbine capacity in kW, by default 4200.

  • base_hub_height (numeric or array_like, optional) – Baseline turbine hub height in m, by default 120.

  • base_rotor_diam (numeric or array_like, optional) – Baseline turbine rotor diameter in m, by default 136.

  • reference_wind_speed (numeric, optional) – Average wind speed corresponding to the baseline turbine design, by default 6.7.

  • min_tip_height (numeric, optional.) – Minimum distance in m between the lower tip of the blades and the ground, by default 20.

  • min_specific_power (numeric, optional) – Minimum specific power allowed in kw/m2, by default 180.

  • max_hub_height (numeric, optional) – Maximum allowed hub height, any higher optimal hub height will be reduced to this value, by default 200.

  • tech_year (int, optional) – The year defining the baseline turbine design that shall be used.

  • baseline_turbine_fp (str, optional) – A json or csv file that contains baseline turbine parameters. Will replace the default data.

Returns:

Returns a the suggested values of hub height in m, specific power in W/m2, and capacity in kW as dictionary when numeric values are input or as a pandas DataFrame when array-like objects are input.

Return type:

dict or pandas DataFrame

Notes

The default baseline onshore turbine has 4200 kW capacity, 120m hub height, and 136m rotor diameter [1]
