12:00 - 13:30 Breakthrough session
Breakthrough sessions  
Onshore      Offshore    


Room: Belleville

A thorough review of abstracts cannot be done overnight – hence the main call for abstracts having closed in May. This is fine in most cases but, as delegates have told us, it is too early to be able to propose the very latest findings. Hence, we hold a call for ‘breakthrough abstracts’ presenting work that is genuinely ground-breaking and has in that form never been made public before. We introduced this at EWEA OFFSHORE 2015 and given the positive outcome, we decided to repeat this at EWEA 2015.

This call for ‘breakthrough abstracts’ took place from 1-14 September 2015. We would like to thank all the submitters forward to a highly interesting breakthrough session at EWEA 2015!

This breakthrough session covers topics from the resource to power performance, from turbines to wind farms and combines measurements and models. In a mixture of scientific and technical presentations attendees will learn about the experience and increasing acceptance of floating lidar technologies, covered by international IEA Wind experts. Turbulence remains of course a challenge for lidar measurements as well as for simplified but manageable models. A talk on turbulence intensities in large offshore wind farms will shine some light on the performance of models if compared with real measurements. The combination of turbulent fluctuations and large rotor blades leads to non-trivial blade deflections and modern control methods try to cope with this. However in order to be successful, the current deflection needs to be known and session attendees will see a new measurement concept that promises do this and which has just been tested on a large turbine this August. Finally combining this knowledge of turbulent flows with aero-elastic turbine models will be used to predict power performances in non-standard conditions.
 

Learning objectives

After attending this session, delegates will be able to:

  • estimate the current possibilities of using floating lidars in offshore wind farms.
  • quantify the performance of commonly used turbulence intensity models in real life.
  • explain how blade deflection of large blades in turbulent flows can be tackled.
  • evaluate the potential of using large wind farm data sets and modern computer power.

Presenter's biography

Biographies are supplied directly by presenters at EWEA 2015 and are published here unedited

Dr Argyle earned his Master’s degree in meteorology from The University of Reading. After which he has worked for multiple large utility companies as a data analyst of unbilled revenue sources and as a business intelligence consultant specialising in data visualisation.

He earned his PhD in modelling offshore wind resource assessment from Loughborough University, specialising in atmospheric stability and its incorporation into CFD simulations. He now works as a research associate at the same university.
