1. Wind Turbine Drive Train System Dynamics ; Multibody Dynamic Modelling and Global Sensitivity Analysis
Abstract : To facilitate the design and production of highly efficient and reliable wind turbine drive trains, this thesis deals with the mathematical modelling and analysis of drive train system dynamics. The drive train is considered as the subsystem of the wind turbine that transfers mechanical power from the rotor hub to the generator, and thereby plays an important role in the system dynamics and the efficiency of wind turbine operation.

2. Drive train system dynamic analysis; Application to wind turbines
Abstract : To facilitate the design and production of highly efficient and reliable wind turbine drive trains, the project deals with the mathematical modelling and experimental study of drive train system dynamics.A typical drive train is considered as the subsystem of a wind turbine that transfers mechanical power from the rotor hub to the generator, and thereby plays an important role in the system dynamics and efficiency of wind turbine operation.

3. Vertical Axis Wind Turbines : Tower Dynamics and Noise
Abstract : Vertical axis wind turbines (VAWTs) have with time been outrivaled by the today common and economically feasible horizontal axis wind turbines (HAWTs). However, VAWTs have several advantages such as the possibility to put the drive train at ground level, lower noise emissions and better scaling behavior which still make them interesting for research.

4. Modeling of Wind Turbines for Power System Studies
Abstract : The power quality impact of wind turbines on the electric grid and the response of the wind turbines to faults in the electric grid are investigated in this thesis. A detailed model of a stall-regulated, fixed-speed wind turbine system capable of predicting the flicker impact on the connected grid is presented and compared with field measurements. READ MORE
