The invention provides a wind turbine comprising a load carrying structure and an energy generating unit. The load carrying structure is connected to the energy generating unit and holds the energy generating unit above ground. The energy generating unit houses a facility which requires a particular ...
A wind turbine simulator for wind energy conversion systems has been developed with a view to design, evaluate, and test of actual wind turbine drive trains including generators, transmissions, power-electronic converters and controllers. The simulator consists of a 10-hp induction motor (IM) which...
In order to tackle the mentioned problems, a novel cross-axis-wind-turbine (CAWT) is conceptualized to extract wind energy from both the horizontal and vertical directions of the on-coming winds to maximize the wind energy generation. The CAWT consists of three vertical blades and six horizontal...
Wind system to convert energy, comprising - at least one kite (1) that is driven from the ground, immersed in at least one wind current W; - a vertical axis wind turbine (2) placed at ground level, said wind turbine (2) which is equipped with at least one arm (3) connected through...
The aim of this chapter is to provide a summary of the numerical methods available to carry out long term prediction analysis of offshore wind turbine foundations. Different available methods of analysis are discussed. Wind Energy: A hand book for onshore and offshore turbines, ISBN 978-0-12...
In wind turbine fatigue design it is customary to use the partial safety factor approach: loads are inflated by some factor, while material fatigue strength is decreased in calculations. Values for partial factors used originally come from civil engineering standards for utility buildings and bridges,...
In last years people have begun to give more importance to wind power as an alternative to fossil fuels. What do you think? Learn more about wind energy.
In this paper, a new algorithm for utilizing energy storage is proposed and applied on floating wind turbine economics. The proposed algorithm's decision making on storing energy or selling electricity onto the grid is based on the electricity price, which makes it unique and different from simila...
We propose an experimental study on the influence of the tip speed ratio on the spatial development of a wind turbine wake. To accomplish this, a scaled wind turbine is tested in a wind tunnel, and its turbulent wake measured for streamwise distances bet
