Probabilistic treatment of IEC 61400‐1 standard based extreme wind events

Publikováno v: Wind Energy, Vol 27, Iss 11, Pp 1319-1339 (2024)

Abstract The procedure to estimate the amplitude of the special wind events according to IEC 61400‐1 as proposed by Larsen is reviewed. Corrections are specified that yield larger amplitudes for the extreme operating gust (EOG) and the extreme cohe

A method to find the 50-year extreme load during production

Autor: Ronald A. Bos, Dick Veldkamp

Publikováno v: Journal of Physics: Conference Series, 753

An important yet difficult task in the design of wind turbines is to assess the extreme load behaviour, most notably finding the 50-year load. Where existing methods often focus on ways to extrapolate from small sample sizes, this paper proposes a di

A probabilistic evaluation of wind turbine fatigue design rules

Autor: Dick Veldkamp

Publikováno v: Wind Energy. 11:655-672

In wind turbine fatigue design, it is customary to use the partial safety factor approach: loads are inflated by some factor, while material fatigue strength is decreased in calculations. Values for partial factors used originally come from civil eng

Power output of offshore wind farms in relation to atmospheric stability

Autor: Dick Veldkamp, Laurens Alblas, W.A.A.M. Bierbooms

Publikováno v: Journal of Physics: Conference Series 555, 2014
Journal of Physics: Conference Series 555 (2014) 012004

Atmospheric stability is known to influence wind farm power output, by affecting power losses due to wakes. This research tries to answer what atmospheric stability does to the power production and how conventional simulations using the Jensen wake m

Implementation of a Mixing Length Turbulence Formulation Into the Dynamic Wake Meandering Model

Autor: Gunner Chr. Larsen, Dick Veldkamp, Rolf-Erik Keck, Helge Aagaard Madsen

Publikováno v: Journal of Solar Energy Engineering. 134

The work presented in this paper focuses on improving the description of wake evolution due to turbulent mixing in the dynamic wake meandering (DWM) model. From wake investigations performed with high-fidelity actuator line simulations carried out in
