Dynamic Response Analysis of Wind Turbine with Tuned Mass Damper under Typhoon Conditions

Abstract:

The wind power is increasingly developed, and the tropical weather condition is a challenge for flexible wind turbine structure. It is essential to get the structure response of wind turbine under typhoon conditions, and then solutions to reduce the load should be found. This article firstly discusses characteristics of typhoon suitable for wind turbine loads calculation, and then a simplified model with two degrees of freedom is got in two directions separately, according to the experiences of high-rise structure to mitigate vibration and theory of vibration absorber, passive TMD systems are put to the wind turbine structures in longitudinal and lateral direction. After that a medium complicated aero-elastic software FAST-SC is used to simulate transient and also fatigue conditions, the tower top displacement and tower base bending moment are evaluated, TMD systems can help reduce the transient load and fatigue loads of flexible wind turbine structures.
