Franca, B.M.R. (author)In recent years the global demand for sustainable energy has risen. In search of new sustainable energy sources, Delft University of Technology’s KitePower group developed an airborne wind energy system. This system is based on a pumping cycle principle where a kite is reeled out with high traction forces while turning a generator, and reeled...master thesis 2014

Verhaegh, Max (author)Offshore wind energy is expected to generate a large part of Europe’s sustainable electrical energy by the year 2020. In the design of an offshore wind farm a large number of components interact with each other, resulting in a certain cost of electricity. In order to reduce these costs of electricity the design of an offshore wind farm can be...master thesis 2014

Striedinger, A.M. (author)In this study, the offshore wind farm effects of Thanet (300 MW) in the U.K, and of Middelgrunden (40 MW) in Denmark were analyzed in a meso-scale numerical prediction model, whilst working at MeteoGroup. For the final analysis of Middelgrunden, the model is validated with measurement data from Middelgrundens Vindmøllelaug. The model uses...master thesis 2014

Geschiere, N.H. (author)This thesis investigates the dynamic modelling of a kite power system. The goal was to create a model that is able to capture the complex flight dynamic behaviour of a kite. A proof-of-concept already existed. From that work the steady fluid-structure interaction (FSI) module, using finite elements (FE), was used and coupled to a bridle and...master thesis 2014

Chrysochoidis-Antsos, Nikolaos (author)This research work proposes the initial design considerations of the safety system of the Deepwind offshore floating vertical axis wind turbine. Deepwind is a wind turbine model and prototype development project under the umbrella of the 7th European Framework Programme. The safety system is one of the aspects of this project and it is dealt...master thesis 2014

Dewan, A. (author)The offshore wind industry is growing fast with an average annual market growth rate of almost 7% in the next five years. Service of wind turbines has proven to be expensive and difficult, especially offshore. A well-coordinated support organisation, optimized logistic and maintenance strategies are required to effectively reduce the costs...master thesis 2014

Villanueva Lopez, H.M. (author)Power curves are a fundamental element of any wind resource assessment. These are required to estimate how much energy a wind turbine will convert. The theoretical power curves are validated with measurements in test sites, however they may not be fully applicable in different wind climates as they are dependent on the site where, and the...master thesis 2014

van den Broek, T. (author)To compete more successfully with other sources of energy, a decrease in the costs of offshore wind energy needs to be achieved. Operation and maintenance costs represent a large share of these costs. In order to reduce these costs new developments and strategies are considered for operation and maintenance of wind turbine components. Condition...master thesis 2014

van der Knaap, E.F. (author)Models of kites with inflatable support structures that are both fast and accurate can accelerate the development of airborne wind energy systems. The fast particle system approach has not yet been used to model inflatable beam structures. The goal of this research is to investigate if the bending behaviour of inflatable beams can be modelled...master thesis 2013

Schelbergen, M. (author)The knowledge about Vertical Axis Wind Turbines (VAWT) lags behind the knowledge about Horizontal AxisWind Turbines (HAWT), since most of the development of VAWT’s ceased after the 80’s. A lack of insight exists about how certain design parameters affect the rotor design of a modern VAWT. The objective of this thesis is to gain knowledge about...master thesis 2013

Shan, Y. (author)A cross flow actuator based on a turbine concept is a possible choice for the harvest of the kinetic energy from a dynamic flow. Since there is a large potential of energy contained in the water movement of the ocean, it is fascinating to apply turbines to extract energy. In marine flows, currents can be described as steady since their flow...master thesis 2013

Ying, T. (author)Load simulations play an important role in the design, certification and optimization procedures for the development of reliable and cost efficient offshore wind turbines (OWTs). For load simulations of OWTs, aero-hydro-servo-elastic tools are used. However, the joint flexibilities of the support structures are generally not modeled in detail in...master thesis 2013

Krishnaswami, C. (author)For a wind turbine, the flow downstream of the turbines (wake) is influenced by the power extraction process. This causes a momentum deficit behind the rotor, resulting in lower velocities in the wake than the free-stream velocity. Wind turbines in a wind farm are likely to operate in the wakes of upstream turbines. This drops the power...master thesis 2013

Mulders, R.J.W.M. (author)Thunderstorm gusts can be severe and inflict major damage to high buildings such as wind turbines. These gusts are caused by the downburst emanating from the thunderstorm cloud. In this research, thunderstorms are modelled for wind turbine design. The results of this study might help make the design of wind turbines thunderstorm-proof. Not only...master thesis 2013
