Abstract

In order to study the effects of different blade positions on wind-included vibration responses of a large wind turbine tower-blade system under a stopped status,a 3 MW wind turbine with 3 blades developed by Nanjing University of Aeronautics and Astronautics was studied.First of all,the effects of eight different blade positions on the flow field and aerodynamic performances of the wind turbine system under stopped status were simulated with the large eddy simulation(LES).In order to verify the effectiveness of the LES method,the simulation results were compared with the actual test data of home and abroad.Then the finite element method was used to analyge dynamic characteristics and wind indaced vibration responses of the wind turbine tower-blade coupled model with different blade positions under a stopped status.The results showed that different blade positions have obvious effects on the flow characteristis of the wind turbine tower frame and the aerodynamic force distribution;the effects of different blade positions on the wind-induced vibration responses of the upper-middle part of the tower are the maximum;the mean square deviation between fluctuating displacements of windward side and leeward side is larger,its maximum value occurs at the tower top 350°position under the operation condition of 8;the maximum bending moment of the towerbottom appears at the annular 330°postion under the operation condition of 2;the peak displacements of 3 blade tips along the wind reach more than 2.5 m under the operation condition of 5.The study indicated that the effects of different blade positions under a stopped status should be considered for the anti-wind design of large wind turbine systems.
