Abstract

In this project of Thesis I worked with the "Università degli Studi di Padova" and the "University of Glasgow", in association with "Gaia Wind", company that realizes wind turbines with one of its plants in Glasgow. Target of this project was to analyze the Wind Turbine (WT) and the conversion of wind energy into electric energy. With this purpose a small turbine 11[KW] with a Induction Generator (IG) was study; at first with fixed-speed functioning, after developing a variable-speed strategy, where the difference of functioning was related to the supply frequency. In the first part of the thesis the reader is guided through all the most important equations and graphics, allowing to get familiar with such complex topics. Subsequently a Matlab simulation was created to understand the behaviour of the wind turbine and the consequence of a parameter's change during the laboratory rig development. Finally a Test rig was completely implemented, with a side representing the Turbine (scaled to our components) and the other side emulating the Wind behaviour. With this Rig some laboratory tests are showed to validate the studies
