Design of an Electromechanical Coordination Vibration Suppression Method for VAWT Main Spindle

Abstract:

Because of its advantageous aerodynamic performance, the vertical-axis wind turbine (VAWT) has gained more and more attention. This paper studies the vibration characteristic of the VAWT main spindle, and presents a mechanical and electromechanical coordination vibration suppression method for the VAWT main spindle. The proposed method can measure main spindle current vibration intensity in real-time. And when the main spindle vibration intensity exceeds preset critical control threshold value, the method can use both the on-line intelligent analysis decision and the mechanical and electromechanical coordinated controller to suppress the main spindle vibration, as well as to make the VAWT maintain mechanical stability. At the same time, the method can ensure the VAWT meets maximum wind energy capture efficiency as far as possible.
