This paper proposes a per-blade deterministic equivalent wind speed concept to excite higher than 3rd order drive train models. Wind shear and tower shadow effects are suitably added. In the comprehensive model, which includes turbine and site-specific parameters, several features are added i.e., height constraint is removed; the per-blade concept is applied; a higher order approach for wind shear is tried; the m factor relating spatial - mean wind speeds is reviewed and qualified. From the simulation results, it is made known that the wind, as seen at the hub height, is a conservative value when blade dynamic features are to be individually taken in the wind turbine high-order drive-train modeling. This development is suitable for time domain simulations of a wind turbine, particularly in real-time applications.
