rotor_equiv_ws(data, heights)[source]

Calculate rotor equivalent wind speed. Follows implementation in ‘How wind speed shear and directional veer affect the power production of a megawatt-scale operational wind turbine. DOI:10.5194/wes-2019-86’

Parameters:
  • data (dict) – Dictionary of arrays for windspeeds/winddirections at different hub heights. Each dictionary entry has (spatial_1, spatial_2, temporal)

  • heights (list) – List of heights corresponding to the windspeeds/winddirections. rotor is assumed to be at mean(heights).

Returns:

rews (ndarray) – Array of rotor equivalent windspeeds. (spatial_1, spatial_2, temporal)
