14th eawe PhD Seminar

18 - 20 September 2018 - Brussel, Belgium

Senior PhD Workshops

This year features for the first time Senior PhD workshops. These are 6 extended (45 min) sessions in which senior PhD 's transfer their knowledge and give a general introduction to a specific topic.
Following topics are confirmed: 

  • Working with LiDAR data: 

    The wind LiDAR workshop is targeted towards individuals who would like to improve their understanding of LiDAR technology as well as get a chance to work with real measurement data. As such, it will feature both an informational and hands-on component.

    • The schedule includes:
      -General introduction to LiDAR for wind energy
      -Overview of available systems (commercial & research)
      -Summary of different measurement techniques
      -Tutorial/exercise using real measurement data

    Example code (using Python v3) will be provided in the form of a Jupyter notebook.
    You can either simply follow along, or join on your own computer to modify and extend the analysis. For the latter, it would be helpful to come with the latest build of Anaconda already installed (Python 3.6):

  • Working with SCADA data:

    Ok, you know how the wind blows... but, how do wind turbines really work on site and how do they fail?
    In this workshop you will learn about the challenges related to operation and maintenance of wind turbines and the current efforts towards reducing their related costs, including predictive maintenance strategies. Aspects of condition monitoring solutions will be covered, along with practical examples from real wind turbine case study failures. Machine learning, diagnostics, SCADA, vibrations… if you want to learn more about these buzzwords join our session!

  • Airborne wind energy:

    Airborne Wind Energy is an emerging technology in the field of renewable energy. The key idea is to harvest high altitude wind energy by means of tethered airborne systems, such as aircrafts or kites. The technology makes it possible to operate at heights exceeding those of conventional wind turbines, thus tapping into untouched wind resources. In this seminar, the underlying working principles along with the historical development of the technology will be introduced. Further, several concepts, in particular the on-board turbine-based power generation and the ground-based pumping-cycle power generation, and their practical implementations will be presented. Finally, the challenges faced by the Airborne Wind Energy community and the proposed solutions will be discussed.

  • Vertical Axis Wind Turbines (VAWT):

    The development of floating wind turbines has given rise to concepts based on a vertical axis rotor. These rotors are less prominent in current bottom-fixed application but show interesting features for floating applications. For example, Vertical Axis Wind Turbines (VAWTs) can have lower centers of gravity and thrust which improves their stability at sea. The overall Cost of Energy may thus be lower than for Horizontal Axis Wind Turbines (HAWTs). However, their aerodynamics and dynamic behavior at sea can be very complex to model.

  • Turbine Modelling:

    Wind turbines are complex structures that are designed using simulation models. However, wind turbine components like blades or foundations can hardly be modelled independently of each other, but should be analysed using a coupled aero-servo-dynamic model in time-domain that takes turbine, tower, substructure, foundation, etc. into account. 
    That is why this workshop deals with coupled wind turbine modelling. It covers an introduction in the state-of-the-art modelling. Afterwards, some limitations – concerning accuracy, deterministic parameters, and simulation data – are discussed in details. 

      1. State-of-the-art turbine modelling: FAST, Bladed, or HAWC2.
      2. Limitations of state-of-the-art models and more accurate alternatives
      3. Turbine reliability: Deterministic vs. probabilistic modelling
      4. Can numerical modelling tell us everything?

  • Marine ecology:

    Offshore wind turbine foundations are rapidly colonised by marine organisms, which form complex and highly dynamic communities. This process of biological colonisation, often referred to as biofouling or marine growth, can roughen the foundation and increase cross-sectional surface areas, affecting loading on fixed turbines. However, it is not yet understood how biofouling would affect floating turbines and their mooring systems.
     In addition, although it is often thought to be environmentally benign, or even beneficial, much like planting a forest in a field, an offshore wind farm will change the ecosystem. By forming a network of artificial reefs, wind turbines might have profound effects on processes and functions associated with the local marine ecosystem. Although there may be benefits to the environment, there may also be unforeseen trade-offs. But can we expect the same effect with floating structures installed further offshore and in deeper waters?
     In this workshop we will address the challenges that wind farms present for marine ecosystems; as well as the challenges marine ecosystems present to the structures themselves. We will compare fixed and floating turbines and discuss uncertainties facing new technologies as we push further offshore.
