2. 11. Ride The Wind : Symbiotic Business Model Innovation for the Chinese Wind Power Industry

   Author : Lihua Liu; Mike Danilovic; Maya Hoveskog; Susan Lijiang Sun; Bingwen Yan; Högskolan i Halmstad; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Symbiotic Business Model; Business Model Innovation; Wind Power Innovation; China; Goldwind; 共生的商业模式，商业模式创新，中国，风电行业创新，金风科技;

   Abstract : China has become one of the world’s leading countries in renewable energy, particularly in wind power. Goldwind Science and Technology has become not only the largest wind turbine manufacturer in China, but also one of the largest in the world. READ MORE

4. 12. Wind Turbine Noise and Natural Sounds : Masking, Propagation and Modeling

   Author : Karl Bolin; Mats Åbom; Jens Forssén; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind turbine noise; models of natural sound sources; masking; Acoustics; Akustik;

   Abstract : Wind turbines are an environmentally friendly and sustainable power source. Unfortunately, the noise impact can cause deteriorated living conditions for nearby residents. The audibility of wind turbine sound is influenced by ambient sound. This thesis deals with some aspects of noise from wind turbines. READ MORE

5. 13. Modeling of PMSM Full Power Converter Wind Turbine with Turn-To-Turn Fault

   Author : Joachim Härsjö; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turn-to-turn; full power converter wind turbine; permanent magnet synchronous machine PMSM modeling; fault detection.; fault; Wind turbine modeling; Wind energy;

   Abstract : Over the past several years the number of renewable energy installations has shown a strong increase rate. Due to the ambition to close down fossil and nuclear power plants, this rate of increase is not expected to decline during the coming decades. In particular, wind energy represents one of the most dominant renewable energy sources. READ MORE

6. 14. Wind Turbine Sound in Cold Climates

   Author : Kristina Conrady; Anna Rutgersson; Karl Bolin; Sabine von Hünerbein; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric acoustics; wind turbine sound; outdoor sound propagation; cold climates; Meteorology; Meteorologi;

   Abstract : The increase in the number of wind turbines (WTs) in populated areas in cold climates increases the number of people potentially being affected by WT sound. Outdoor sound propagation is strongly dependent on meteorological conditions, however, limitations in the knowledge exist regarding the implications of meteorological conditions in cold climates.

7. 15. Numerical computations of wind turbine wakes

   Author : Stefan S. A. Ivanell; Dan Henningson; Peinke Joachim; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Actuator Line Model; Actuator Disc Model; Wind Turbine Wake; CFD; LES; EllipSys3D; Fluid mechanics; Strömningsmekanik;

   Abstract : Numerical simulations of the Navier-Stokes equations are performed to achieve a better understanding of the behaviour of wakes generated by wind turbines. The simulations are performed by combining the in-house developed computer code EllipSys3D with the actuator line and disc methodologies. READ MORE
