Experimental investigations on the performance of a wind turbine scale model with focus on electric and mechanical quantities / Louis Herbert 

Public ISBD Titre : Experimental investigations on the performance of a wind turbine scale model with focus on electric and mechanical quantities Type de document : Travail de fin d'études Auteurs : Louis Herbert, Auteur ; Jeroen Van Beeck, ; Patrick Hovine, Editeur : ECAM Année de publication : 2019 Note générale : von KARMAN Institute for Fluid Dynamics Langues : Anglais (eng) Index. décimale : TFE - Electromécanique Résumé : With society becoming increasingly mindful of the impacts of fossil fuels, renewable energy is on the rise. Wind is one of the most plentiful and widely available natural resources available on our planet. Meanwhile, wind turbines have been installed all over the globe both onshore and offshore. Hence, with the rise in the use of wind energy, more and larger clustered wind farms are expected to appear. An important aspect of a wind-farm design is the optimization of the wind-farm layout. Previous studies have focussed on the wake meandering effect using scaled wind turbine models placed in wind farms in wind tunnels. However, no study has yet been established on the electrical and mechanical aspects regarding the energy generation of wind turbine models inside a scale model wind farm. This Master's Thesis aims to gain deeper insight into the electrical and mechanical characteristics of a specific wind turbine model inside a wind turbine farm. The wind turbine models are placed in a wind tunnel that simulates on shore as well as offshore conditions. The experiment is carried out inside the large scale atmospheric boundary layer wind tunnel at the von Karman Institute for Fluid Dynamics. Different flow conditions are to be tested together with various loads on the generator. Electrical as well as mechanical outputs from the wind turbine are analysed. The first test consists in testing one single turbine. Afterwards, a wind farm with several wind turbines is tested to observe how yawing of the upstream turbine affects the efficiency of wind turbines placed downstream.
