windpowerlib.wind_turbine.WindTurbine¶

class windpowerlib.wind_turbine.WindTurbine(turbine_name, hub_height, d_rotor, cp_values=None, p_values=None, nominal_power=None, fetch_curve='cp')[source]¶

Defines a standard set of wind turbine attributes.

Parameters:

turbine_name (string) – Name of the wind turbine type. Use get_turbine_types() to see a list of all wind turbines for which power (coefficient) curve data is provided.
hub_height (float) – Hub height of the wind turbine in m.
d_rotor (float) – Diameter of the rotor in m.
cp_values (pandas.DataFrame) – Power coefficient curve of the wind turbine. The indices of the DataFrame are the corresponding wind speeds of the power coefficient curve, the power coefficient values are listed in the column ‘cp’. Default: None.
p_values (pandas.DataFrame) – Power curve of the wind turbine. The indices of the DataFrame are the corresponding wind speeds of the power curve, the power values are listed in the column ‘P’. Default: None.
nominal_power (float) – The nominal output of the wind turbine in kW.
fetch_curve (string) – Parameter to specify whether the power or power coefficient curve should be retrieved from the provided turbine data. Default: cp.

turbine_name¶: string – Name of the wind turbine type. Use get_turbine_types() to see a list of all wind turbines for which power (coefficient) curve data is provided.

hub_height¶: float – Hub height of the wind turbine in m.

d_rotor¶: float – Diameter of the rotor in m.

cp_values¶: pandas.DataFrame – Power coefficient curve of the wind turbine. The indices of the DataFrame are the corresponding wind speeds of the power coefficient curve, the power coefficient values are listed in the column ‘cp’. Default: None.

p_values¶: pandas.DataFrame – Power curve of the wind turbine. The indices of the DataFrame are the corresponding wind speeds of the power curve, the power values are listed in the column ‘P’. Default: None.

nominal_power¶: float – The nominal output of the wind turbine in kW.

power_output¶: pandas.Series – The calculated power output of the wind turbine.

Examples

>>> from windpowerlib import wind_turbine
>>> enerconE126 = {
...    'hub_height': 135,
...    'd_rotor': 127,
...    'turbine_name': 'ENERCON E 126 7500'}
>>> e126 = wind_turbine.WindTurbine(**enerconE126)
>>> print(e126.d_rotor)
127
