Garry Yuan Kwan, Garry (author)Idling instabilities of large wind turbines in extreme winds is a relatively well known problem for manufacturers, at least in terms of the results in calculations. However, many are still sceptical of how realistic such instabilities are in actuality due to limitations in the current state of the art aeroelastic tools.<br/>The overall aim of...master thesis 2017

Li, Ang (author)The aim of this thesis is to evaluate the influence between the two counter-rotating VAWT rotors with the Double Actuator Cylinder (DAC) model which will be validated against the panel code. The DAC model is developed from the original Actuator Cylinder (AC) model which includes the Modified-Linear (Mod-Lin) correction. The original AC model for...master thesis 2017

Jerez Venegas, Marcos (author)Airborne wind energy is a new research field that aims to harvest winds at high altitudes. The pumping kite concept investigated at the Delft University of Technology is based on leading edge inflatable kites that divide a generation cycle into three phases: traction, retraction, and transition. This research project aims to optimise the...master thesis 2017

Kaur, karanbir (author)Experimental Analysis of an Actuator Disk under cyclic unsteady loading.<br/>Wind Energy is one of the cleanest forms of energy. It does not contribute to the greenhouse gases and is also one of the least expensive forms of renewable energy. Due to this, number of wind turbines are increasing annually. Therefore, it is crucial to understand the...master thesis 2017

Nikiforakis, Ioannis (author)The application of stability checks in simulated offshore wind structures is performed through tools that are established in the offshore wind industry. In particular, the structure should fulfill certain strength and fatigue criteria among which Fatigue Limit States (FLSs) checks are critical. In terms of the process, fatigue assessment can be...master thesis 2017

Marchena, C.J. (author)This research aims to investigate the validity of the standard power curve (i.e. measured power curve M-PC) in non-standard wind conditions and the integration of those results into recommended practices for future warranty negotiations. The Power Performance Testing (PPT) is carried out on a ABC1 with rotor diameter between 105-110m and rated...master thesis 2017

Keus, R. (author)Monitoring and optimising turbine performance are important tasks of a wind energy operator. However, monitoring activities are expensive and the current state-of-the-art in this field could be improved. A newly developed Avent five-beam Lidar was tested and the impact of heterogeneity on Lidar measurements was analysed. Also, the effect of...master thesis 2017

Bagde, R. (author)The increasing globalwarming and climate change has boosted research on sustainable energy in the last few decades leading to a lot of research being carried out on wind energy. Wind turbines have played a major role in harvesting wind energy withHorizontal AxisWind Turbines (HAWTs) being the dominant design. However, for urban and offshore...master thesis 2017

De Tavernier, Delphine (author)One of the most commonly used flow control techniques to trim the aerodynamic performance of wind turbine blades are vortex generators. This passive device, which does not require any active energy, is gaining an increasing interest in this sector especially due to the trend of increasing wind turbine size. Vortex generators are a flow control...master thesis 2016

Ploumakis, E. (author)Wake effects in wind farms are a major source of power production losses and fatigue loads on the rotors. It has been demonstrated that in large wind farms the only source of kinetic energy to balance that extracted by the turbines is the vertical transport of the free-stream flow kinetic energy from above the wind-turbine canopy. This chapter...master thesis 2016

Kaloritis, G. (author)New concepts for support structures of offshore wind turbines have gained interest in the industry and are examined for intermediate and deep water depths in order to unlock new offshore potential markets. One of the main proposals that has already been commercialized is the three or four leg full height lattice structure. The fatigue assessment...master thesis 2016

Maselis, A. (author)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....master thesis 2016

Houf, D.P. (author)Due to its inherent dynamic stability the Vertical Axis Wind Turbine (VAWT) is a strong candidate for large (10-20 MW) floating offshore applications. However, there is room for improvement considering the VAWT’s aerodynamic and structural performance, so as to increase its cost-effectiveness. This thesis explores the VAWT’s potential of...master thesis 2016

Cool, G.A. (author)Wind assessment of new locations prior to the installation of wind turbines is an established process. However, this process is still very costly. The common way to measure offshore wind profiles is the usage of met masts, which get more expensive with increasing water depth and hub height. Recently, wind measurement LiDARs are installed on...master thesis 2016

Karadayi, M.C. (author)Kite Power research group at TU Delft developed the KiteSim framework for dynamic simulation of crosswind kite power systems. Currently, KiteSim has the capability to simulate leading edge inflatable kites. The use of rigid wing kites in crosswind kite power systems is becoming widespread. Accordingly, KiteSim framework is planned to be...master thesis 2016

Knoben, V.L. (author)The capability to acquire accurate and reliable measurements of the wind is essential for wind turbine validation and wind resource assessment. These measurements are typically done with tall meteorological masts (met-masts). However, as of 2004 the concept of remote sensing has started to become specialised in wind energy. A key requirement...master thesis 2016

Hartvelt, M. (author)The current practice in aerodynamic design and load analysis of wind turbines is to use codes based on the Blade Element Momentum theory (BEM). These models are computationally very efficient but are limited in the physical representation of certain flow phenomena, such as yawed flow, dynamic inflow and root/tip flow, for which engineering...master thesis 2016
