The turning of kites: A quantification of known theories

A method is introduced to measure the in flight flow field and geometric shape of an energy producing kite. The method is applied on beach tests during controlled flight maneuvers as well as equilibrium positions. The measurements of different sensors are validated by use of independent coherence of the found results. After this the deformations...

Lidar and MCP in Wind Resource Estimations above Measurement-Mast Height

Modern multi-megawatt wind turbines are tall and may reach heights of 200 meter. Tall wind turbines require measurements above typical measurement mast height. As tall measurement masts are expensive and cumbersome to install, wind measurements at hub height are scarce. Currently, the use of lidars in wind measurement campaigns is increasing....

Layout Optimization of Offshore Wind Farms affected by Wake effects, Cable topology and Support Structure variation

As part of the effort to reduce the cost of offshore wind energy, this MSc Thesis deals with the layout optimization of an Offshore Wind Farm affected by wake effects, cable topology and support structure variation. The main objective of the current MSc Thesis is to investigate how important each of these aspects for the layout optimization is....

An Investigation of the Non-Linear 3D Flow Effects Relevant for Leading Edge Inflatable Kites

The kite power group at TU Delft is currently researching the use of leading edge inflatable (LEI) kites for use in power generation. A thorough understanding of the aeroelastics of these kites is paramount to the development of system simulation models and optimum kite and system designs. The current lack of understanding is therefore seen as a...

Global opportunities for airborne wind

It is the objective of this graduation research to determine the nations with the highest deployment opportunity for airborne wind energy (AWE) generation systems. Compared to conventional, ground based, wind energy systems, the flying structure of the airborne wind turbine substitutes the rotor blades and a tether substitutes the tower. These...

Small Scale Fluid Power Transmission for the Delft Offshore Turbine

The Delft Offshore Turbine (DOT) project is a research project within the Delft University Wind Energy Research Institute (DUWIND). The main objective of the DOT research project is to make offshore wind energy a competitive energy source. One of the research lines in the DOT project is considering the centralization of electricity generation...
