Calculate air density dependent power and ct values, as given by two individual files.

The structure of each file is: ws,1.225,0.950,0.975,…,1.275

The first column represents wind speed in m/s and the subsequent columns are air density values (not neccessarily in order).

Attributes¶

source_P: str or pandas.DataFrame

The file path for the power curve, static name, or data

source_ct: str or pandas.DataFrame

The file path for the ct curve, static name, or data

WSCT: str

The wind speed variable for ct lookup

WSP: str

The wind speed variable for power lookup

rpars_P: dict, optional

Parameters for pandas power file reading

rpars_ct: dict, optional

Parameters for pandas ct file reading

ipars_P: dict, optional

Parameters for scipy.interpolate.interpn

ipars_ct: dict, optional

Parameters for scipy.interpolate.interpn
