Design a small direct drive wind power generator

Abstract

This paper presents the design and a small scaling prototype of a direct drive wind turbine generator. First, the potential of wind energy in Vietnam is discussed. The electromagnetic parts of permanent magnet synchronous generator are sized using the optimisation approach based on the analytical model, aiming to minimize the active masse, taking into account the technical and manufacturing constraints. Then, the modelling of this optimal solution using Finite Element Analysis (FEA) method is simulated in transient mode, in order to verify certain physical phenomena in the generator. Finally, a prototype is manufactured and experimental results are shown.
