16. Vertical Axis Wind Turbines : Tower Dynamics and Noise
Sammanfattning : 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.

17. Blade force measurements and electrical torque ripple of a vertical axis wind turbine
Sammanfattning : Wind power has become an attractive alternative for clean energy production. Horizontal axis turbines are increasing in power rating and are maturing as products. The cost of maintenance, noise levels and durability are possible concerns of the modern horizontal axis wind turbines. LÄS MER
18. Electromechanics of Vertical Axis Wind Turbines
Sammanfattning : Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maintenance is high and future wind turbines may need to be improved to enable more remote and offshore locations. LÄS MER
19. Demagnetization Studies on Permanent Magnets : Comparing FEM Simulations with Experiments
Sammanfattning : In a world where money often is the main controlling factor, everything that can be tends to be more and more optimized. Regarding electrical machines, developers have always had the goal to make them better. LÄS MER
20. Submerged Transmission in Wave Energy Converters : Full Scale In-Situ Experimental Measurements
Sammanfattning : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. LÄS MER
