Ali Hajnayeb, University of Calgary: Modelling the Effects of Different Types of Faults on the Vibrations of Wind Turbine Drive Trains
For several reasons, the wind turbines height and capacities are growing. This leads to less accessibilities and more difficulties in changing failed components. Therefore, using the components of the drivetrain till their maximum possible time while avoiding detrimental effects on the heath of other components is desired. In this presentation we present a dynamic model of a wind turbine drivetrain with different faults at a time. By using this model, the effects of each type of fault (in the bearings and gears) and their combinations on the lateral and torsional vibrations observed on different points of the system are presented.
