Offshore wind energy is considered a necessary renewable energy resource, that may stimulate the transition from fossil fuels. Following the successful development in Western Europe, offshore wind is quickly gaining momentum in the Asia-Pacific region. At variance with North Sea-based offshore wind turbines, structures installed in the Asia...

Fatigue is often a governing design factor for offshore wind turbines. Since the design of offshore wind turbines includes conservatism, the actual accumulated fatigue damage can be lower than what the turbine is designed for. In this case, the operator can make a decision on life time extension of existing wind turbines. Therefore, it is...

Delamination is one of the common failure types in the fiber composites. The trailing edge in the wind turbine blades, for example, is one of the structural components where the delamination is driven by mode III under predominantly flapwise loading. There has been an extensive effort in developing test procedures and test specimens for...

This thesis presents an individual tip control (IPC) system based on blade tip deflection measurements. The controller is based on novel sensor inputs which measure flapwise tip deflection distance at a high sampling rate. IPC plays a key role in reducing fatigue loads in wind turbine components. These fatigue loads are caused by differential...

Presently, phasor measurement units (PMUs) are the most accurate and advanced time-synchronized technology. PMUs are the main element of the Wide-Area Monitoring, Protection and Control System, the concept that provides an estimate of the actual condition of the system, allowing operators to run online simulations and determine the possibility...

Optimization of structures in a domain with large uncertainties is rather difficult. This also applies for the offshore wind energy sector. For current offshore wind energy development locations with monopile-based support structures the fatigue limit state is the driving design criteria. These analyses are connected with long time domain...

In this report, the issue of pitch control in a Vertical Axis Wind Turbine is tackled. By using and aerodynamic model, a theoretical optimum pitch solution is found and then a simple four-bar mechanism is adapted to that theoretical solution to achieve a simple and elegant control of the pitch in the turbine. The model used is the Actuator...

Material bend-twist coupling has been widely studied in the research community as a passive control mechanism for a wind turbine. However, there is a lack of research in incorporating it in the rotor design process, with little research being conducted for its application to small wind turbines. The present study focuses on this issue by...

The wide scale integration of distributed energy resources (DERs) in the distribution networks (LV/MV) over the last few decades has resulted in new challenges for the protection system. This thesis work explores the possibility to overcome challenges associated with overcurrent protection schemes, which are conventionally employed for...

Given the prime importance of wind tunnel setup when it comes to aero-elastic study, the main intent of this project is to devise a mechanism for supporting system of 2D aero-elasticity experiment in the Red Wind Tunnel Facility at DTU that allows three-degree-of-freedom motion of the rigid model. This project work is mainly inspired by the fact...
