The project aims at quantifying differences in power production and fatigue loads for wind turbines placed in the Baltic sea and in forested, topographically-complex areas compared to turbines placed offshore and in flat terrain. Based on these results, suggestions will be provided on how to optimally site and operate turbines in these conditions. In order to be able to perform these calculations, a new rotor model is required which can take into account the deformations of the blades due to the increased wind shear, turbulence and other transient features of the wind flow that characterize such regions. The results will contribute to the development and optimal operation of wind energy projects in these areas as well as to the long term objectives of a sustainable development of wind power in Swedish conditions.
The project will consider the sequence “from wind to fatigue life”, and by simulation investigate how the site-specific conditions (terrain, forest, etc.) affect the fatigue life of turbines. The project involves CFD simulations to investigate the flow field, wind turbine system simulations to evaluate how this flow field affects wind turbine operation and lifetime of drive train components, and development of maintenance algorithm to reduce down-time and repair waiting time. Later, this research is extended to quantifying turbine response to fluctuations caused in the wind shear profile due to air-sea interaction and subsequent momentum exchange.
