Probabilistic design tool presented on DeepWind 2017 During the EERA DeepWind'2017 from 18-20 January 2017 in Trondheim, Norway, ECN presented a poster about the work done in work package 3. The presented work investigates where cost reductions in the support structure are possible while keeping...►

Within WP2 a study has been performed to improve the drag prediction for thick airfoils for XFOIL like methods. The general methodology of the correction is applicable to a wide range of viscous-inviscid interaction methods using a two-equation lag dissipation integral boundary layer method. The...►

As wind turbine rotors grow in size, maintaining a favourable flow regime over turbine blades is increasingly challenging. Rotational effects, thick airfoil sections and turbulence in the atmosphere give rise to an altogether complex flow regime over the blades. However, in order to deliver the...►

Within WP1, the aim is to improve the availability of electric generator systems by using modular conversion system concepts that are fault tolerant, re-configurable, and self-healing. To address failure rates and improve reliability, an extensive study has been performed on the mechanisms of the...►

Within WP4, ECN develops new methods for controlling wind turbines in the presence of operational uncertainty, such as changes of the aerodynamic properties of the blades (due to, e.g., ice/dirt accretion and blade erosion), and changes of the properties of the support structure (e.g. tower...►

The kickoff meeting of the D4REL project took place on 3 December 2013, about 3 months after the official start of the project (1 September 2013). During the meeting, the project objectives, scope, deliverables and planning were discussed and agreed upon. As several disciplines interplay in the...►
