Precision blade deflection measurement system using wireless inertial sensor nodes

open access: yesWind Energy, 2022
Structural health monitoring on wind turbine blades is a great enhancement for operational safety and failure avoidance. Blade deflection is a key parameter, which is a function of blade geometry and material properties.

Data‐driven virtual sensing and dynamic strain estimation for fatigue analysis of offshore wind turbine using principal component analysis

open access: yesWind Energy, 2022
Virtual sensing enables estimation of stress in unmeasured locations of a system using a system model, physical sensors and a process model. The system model holds the relationship between the physical sensors and the desired stress response.

Decoupled simulations of offshore wind turbines with reduced rotor loads and aerodynamic damping [PDF]

open access: yesWind Energy Science, 2018
Decoupled load simulations are a computationally efficient method to perform a dynamic analysis of an offshore wind turbine. Modelling the dynamic interactions between rotor and support structure, especially the damping caused by the rotating rotor ...

Wind tunnel investigations of DU97‐W‐300‐mod equipped with riblets

open access: yesWind Energy, 2021
A well‐known 30% thick wind turbine aerofoil was partially equipped with riblets, and lift and drag data were measured in a large acoustic wind tunnel. Drag was reduced up to 10%, and lift‐to‐drag ratio increased by up to 30%.

Comparing calibrated analog and dynamical ensemble solar forecasts

open access: yesSolar Energy Advances
Ensemble modeling is a chief strategy for probabilistic forecasting. In weather forecasting, analog ensemble, which operates under the principle that weather patterns often repeat, and dynamical ensemble, which generates equally likely trajectories of ...

Modélisation et simulation par les éléments finies d’un câble électrique à 4 conducteurs soumis aux contraintes générés par les convertisseurs d'électronique de puissance

open access: yesRevue des Énergies Renouvelables, 2015
La compatibilité électromagnétique (CEM) apparaît aujourd’hui comme l’une des contraintes majeures de la conception des structures de l’électronique de puissance et plus précisément sur les convertisseurs et ses associations réseaux et charge. Les câbles

Influence de la température, de la pression et de l’humidité relative de l’air sur le potentiel éolien dans la zone côtière du Bénin dans le Golfe de Guinée

open access: yesRevue des Énergies Renouvelables, 2015
Le Bénin ne possède pas des sources de production d’énergie électrique propre à lui-même. Ceci explique sa dépendance énergétique des pays voisins. Pourtant il possède sur sa côte, dans le Golfe de Guinée, une propagation d’un vent quasi permanent et ...
