The effect of tuned mass damper to the vibration of wind turbine structure model

Abstract

The high generated power of the wind turbine requires stronger wind which is usually at high altitudes. The high constructions are vulnerable to external load such as strong wind. Therefore, it requires the system which can reduce the vibration caused by the wind force. Furthermore, the different form of the wind turbine's tower would affect the vibration of the wind turbine. The aim of this study is to compare the responses of vibration in three different form of wind turbine's tower. The effects of Tuned Mass Damper to each structure vibration were analyzed. The study was conducted both simulation and experimental method in a laboratory scale of the wind turbine model. The simulation results show that the installation of TMD on the wind turbine model reduces the acceleration of the nacelle's mass at the frequency of 3 Hz. The optimum installation of TMD occurs in straight tower type which the addition of TMD could reduce the vibration of the nacelle mass in each frequency variation. The stiffness constant of the TMD affects the vibration reduction of the nacelle mass more than the TMD mass variation.
