MODELISATION, CONCEPTION ET COMMANDE DE GENERATRICES A RELUCTANCE VARIABLE BASSE VITESSE

Abstract : The work presented concerns the design and the control of a low speed generator for wind turbine applications. A 10 kW, 50 rpm generator (typical of an autonomous wind turbine) is studied. The slotted switched reluctance machine (SRM) with great number of teeth is retained. This structure is well adapted to low speed operation allowing the simplification or the removal of the gearbox used with traditional generators.
The electromagnetic structure is optimized by a genetic algorithm coupled with the finite element method. The control of the generator is then treated. The machine is modelled by the finite element method, then the flux characteristics depending on the position and the current are approximated by Krigeage. The machine is controlled thanks to a H half bridge and the optimization of control parameters is carried out.
The system, including a 6/4 SRM (3 kW) in generator mode coupled to a D.C. motor, is implemented and experiments are performed. The two machines control is established on a Dspace 1103 environment. Experiments enable to check on the one hand the validity of modelling by finite elements method, and on the other hand the elaborated control laws.
