The differences of the wind field model between wind turbines and common architectures are investigated. It is indicated that substantial frequency contents are transferred to rotor rotation frequency and its harmonics due to the periodic motions of blade. According to standard von Karman power spectral density (PSD) model and rotationally sampled PSD model, the PSD matrix for turbulence on blades of wind turbine is setup. The longitudinal turbulence’s time serials is simulated based on the superimposition of harmonic waves.
