Modeling and control of a switched reluctance machine for wind generation

Abstract

The rotational speed of a wind turbine is very low compared to that of classical generators, a speed multiplier is then necessary. To eliminate this last, research was directed towards the design of new structures of generators called direct drive (without a speed multiplier). The synchronous and especially asynchronous machines still dominate the market of the wind applications. However, the Switched Reluctance Generator or SRG is regarded as a serious alternative to the traditional generators thanks to its multiple assets (robustness, simplicity of construction, low cost, high torque...). In this work, it is intended to model and simulate a switched reluctance generator 6/4 (SRG) (6 poles with the stator and 4 poles with the rotor) of a power of 30 kW. The design is carried out by finite element method (Software Mag.Net). The modeling and the simulation of this system are carried out under Matlab/Simulink environment.
