New structure for high speed and variable speed wind turbine based switched reluctance generator

This paper presents a new structure for a variable high speed and variable speed wind turbine based on a 12/8 switched reluctance generator (SRG). SR machines have a robust and simple structure because they have no windings or permanent magnets on the rotor, so they are capable of working at high speed applications and rough conditions. A SRG can be used as a reliable stand-alone generator due to several reasons such as high power density, low maintenance, high robustness, and high efficiency. In this paper, basic equations of two operation modes of SRG are extracted. The simulation results of the output waveforms of SRG used as high speed stand-alone generator are presented. The impacts of variations in wind speed are discussed.
