Abstract

The wind rotor tilt angle is an important parameter on the design of wind turbine. This paper investigates its effects on aerodynamic power of wind turbine by using the parameters of NERL 5MW reference wind turbines. A two-dimensional wind speed model including modified tower shadow and wind shear models is established. The rotor tilt angle is parameterized in the model by geometrical and simplified methods. The effects on the speed model is clearly seen by analyzing the model with different tilt angles. The aerodynamic power calculation model is derived from the wind speed model with tower shadow and wind shear. Simulation results show that the tilt angle can reduce the effect of typical periodic disturbances on aerodynamic power fluctuation. The reducing effect happens more obviously in tower shadow effect area than in wind shear area and it decreases with the increase of wind rotor tilt angle.
