摘要	In order to research and explore the physical characteristics of wind turbine aerodynamic unbalance, the effects of wind turbine aerodynamic unbalance on the dynamic characteristics, aerodynamic performance and loads of turbine were studied by employing simulation and experiment methods based on a 2.0 MW three-blade horizontal axis wind turbine. The aerodynamic characteristics and dynamic analysis indicated that the performance of the wind turbine tended to decline. The load fluctuation, on the top of the tower, increased gradually and the flapping load of the blade was obviously different while the vibration acceleration of the nacelle increased with the increment of the imbalance, generated by the installation angle of the blades, The vibration acceleration of the top tower was analyzed by FFT, and the results showed that the characteristics changed significantly. The research illustrated that the monitoring of nacelle vibration acceleration and power curve of wind turbine could identify the degree of aerodynamic imbalance effectively. © 2021, Solar Energy Periodical Office Co., Ltd.
