windpowerlib.wind_turbine.WindTurbine¶

class windpowerlib.wind_turbine.WindTurbine(turbine_name, hub_height, rotor_diameter=None, power_coefficient_curve=None, power_curve=None, nominal_power=None, fetch_curve='power_curve')[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.
rotor_diameter (None or float) – Diameter of the rotor in m.
power_coefficient_curve (None, pandas.DataFrame or dictionary) – Power coefficient curve of the wind turbine. DataFrame/dictionary must have ‘wind_speed’ and ‘values’ columns/keys with wind speeds in m/s and the corresponding power coefficients. Default: None.
power_curve (None, pandas.DataFrame or dictionary) – Power curve of the wind turbine. DataFrame/dictionary must have ‘wind_speed’ and ‘values’ columns/keys with wind speeds in m/s and the corresponding power curve value in W. Default: None.
nominal_power (None or float) – The nominal output of the wind turbine in W.
fetch_curve (string) – Parameter to specify whether the power or power coefficient curve should be retrieved from the provided turbine data. Valid options are ‘power_curve’ and ‘power_coefficient_curve’. Default: ‘power_curve’.

nominal_power¶: None or float – The nominal output of the wind turbine in W.

fetch_curve¶: string – Parameter to specify whether the power or power coefficient curve should be retrieved from the provided turbine data. Valid options are ‘power_curve’ and ‘power_coefficient_curve’. Default: ‘power_curve’.

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