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...

Wind turbines operate in the earth's atmospheric boundary layer - an environment where the climate is turbulent and unsteady. In addition, wind turbines usually operate in clusters (wind farms) and are thus subjected to the unsteady wakes generated by upstream turbines. Because of the unsteady inflow, wind turbines suffer from structural fatigue...

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...

Vortex Generators (VGs) are flow control devices commonly applied in wind turbine blades, among other applications. A significant advance in the design of wind turbine blades would be the integration of vortex generators in the aerofoil optimisation process. Currently, aerofoil optimisation relies on either computational fluid dynamics or...

Offshore wind energy is a fast-growing sector in the energy industry, and the cost of electricity per kilowatt-hour from offshore wind is decreasing significantly. Until now, offshore wind turbines are mainly installed on bottom-mounted foundations, which are economically feasible in shallow waters. This factor has limited the development of...

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...

Noise radiation is in certain countries still a major limitation on the further expansion of wind energy. Until now, the majority of the small wind turbines were sited in sparsely populated areas like open field far from inhabited regions. However, today the tendency exists towards integrating small wind turbines closer to populated areas....

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...

The need for a sustainable water supply is high in many regions worldwide. The coastal city Berbera in Somaliland is one of those places where clean drinking water is not part of everyday life. With wind and saline water being freely available, wind driven reverse osmosis desalination can solve the problem. Existing solutions on wind driven...

The Diffuser Augmented Wind Turbine (DAWT) has been studied periodically over the last five decades. It has already been established by the scientific community that the DAWT is superior to conventional bare wind turbines. In spite of this, the DAWT has not gained popularity worldwide due to high manufacturing cost of the diffuser. There are two...

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...

As part of the effort to reduce the cost of offshore wind energy, this thesis addresses the problem of the design of the infield cable topology for offshore wind farms. The final outcome of the project is a tool that can be implemented in a more general optimization platform for offshore wind farm design. Therefore, the main objective is to...

The unsteady flow conditions experienced by wind turbine blades lead to fatigue loads, that increase the cost of energy. The decrease of the impact of these unsteady loads will most certainly lead to a decrease. In order to alleviate unsteady loads the Smart Rotor Blade approach (J.W. van Wingerden et al [2008]) applies spanwise-distributed...

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...

Communication in wind farm development is complex. A relationship between wind farm developers and residents which is based on reciprocity can lead to the trust and commitment necessary to deal with these complexities. The role of reciprocity is researched in a case study and a network model of reciprocity is developed. Implementing the findings...

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...

In recent years more focus is put on the applications of wind turbines in the urban environment. One of the ways to do this is using a turbine with a vertical axis (a VAWT). This type of wind turbines is around for many centuries. The modern equivalent which is based on lift producing blades only exists for 30 years. In this period airfoils for...
