ABSTRACT

With the increasing size of wind turbines, the rotor-tower interference cannot be neglected. Based on potential flow method, flow field around the tower was simulated and compared to CFD method. The quasi-steady aeroelastic model under tower interference was established and the code was developed. Taking NREL-5MW Reference Wind Turbine as an example, the output power of rotor and the loads of the blades were calculated during tower passage. Results showed that tower interference had little effect on average output power whereas it greatly affected the instant output power and it led great impulsive aerodynamic load at azimuth angle of 180 degree. To flexible blades, the fluctuation of power and the loads of blades were bigger than rigid blades. Then, different wind rotors with shorter or longer main shafts were simulated under tower interference and the rotors with shorter shafts experienced bigger fluctuation. The limiting position calculations of flexible blades under wind trust force showed that the blades of rotors with too short shafts had to dare the risk of crashing into tower.
