1. 11. Modelling and control of large wind turbine

   University essay from Avdelningen för fysik och elektroteknik

   Author : syed hammad zafar; [2013]
   Keywords : ;

   Abstract : In order to make the wind energy an economical alternative for energy production, upscaling of turbine to 10 - 15MW may be necessary to reduce the overall cost of energy production. This production target requires a considerable increase in the turbine size and placing the turbines at high wind speed locations. READ MORE

3. 12. Offshore Wind Turbine Transportation & Installation Analyses Planning Optimal Marine Operations for Offshore Wind Projects

   University essay from Institutionen för kultur, energi och miljö

   Author : Emre Uraz; [2011]
   Keywords : Offshore wind farms; transportation and installations; jack-up vessels; wind turbine installation vessels; design trends in installation vessels; assembly and pre-assembly; project durations; onboard cranes; challenges due to offshore environment; time performance; crane operations;

   Abstract : Transportation and installation of offshore wind turbines (Tower, Nacelle and Rotor) is a complete process conducted over several phases, usually in sequence. There are several factors that can turn this process into a challenge. These factors can either be due to offshore site conditions or the technical limitations of the installation vessels. READ MORE

4. 13. Control of a Synchronous Machine

   University essay from Elektricitetslära

   Author : Jens Olofsson; [2010]
   Keywords : synchronous machine; BLDC; Sensorless;

   Abstract : The VAWT project at Uppsala University has successfully managed to develop a vertical axis wind turbine (VAWT). The VAWT has many benefits compared to the Horizontal axis wind turbines (HAWT) which are the most common wind turbine design today. READ MORE

5. 14. Designing an H-rotor type Wind Turbine for Operation on Amundsen-Scott South Pole Station

   University essay from Institutionen för teknikvetenskaper

   Author : Mats Wahl; [2007]
   Keywords : ;

   Abstract : This thesis focuses on designing the turbine, tower structure and generator for an H-rotor type wind turbine. The produced power will be used for heating of drilling equipment, stored in containers, on the Amundsen-Scott South Pole Station. A 23 kW wind turbine producing 5 kW on average has been designed.

6. 15. Wind effects on high rise buildings.

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Ánundi Fannar Saemundsson; [2007]
   Keywords : Technology and Engineering;

   Abstract : The wind effects on high rise buildings were studied by finding and reading books, articles and studying equations. This was done to calculate the first natural frequency of high rise buildings, wind induced acceleration on high rise buildings and how the comfort criteria of acceleration performing on high rise buildings acts on human bodies living in the building.
