6. Numerical Computations of Wakes Behind Wind Farms : A tool to study Farm to Farm interaction
Sammanfattning : More and larger wind farms are planned offshore. As the most suitable sites to build are limited these new wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. LÄS MER
7. Dynamic Models of Wind Turbines
Sammanfattning : The impact of wind power generation in the power system is no longer negligible. Therefore, there is an urgent need for wind turbine models that are capable of accurately simulating the interaction between wind turbines or wind farms and the power system. LÄS MER
8. Vertical Axis Wind Turbines : Electrical System and Experimental Results
Sammanfattning : The wind power research at the division of Electricity at Uppsala University is aimed towards increased understanding of vertical axis wind turbines. The considered type of wind turbine is an H-rotor with a directly driven synchronous generator operating at variable speed. LÄS MER
9. Noise from wind turbines
Sammanfattning : A rapid growth of installed wind power capacity is expectedin the next few years. However, the siting of wind turbines ona large scale raises concerns about their environmental impact,notably with respect to noise. LÄS MER
10. Ride The Wind : Symbiotic Business Model Innovation for the Chinese Wind Power Industry
Sammanfattning : 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. LÄS MER
