Due to the fluctuations of the wind in wind energy conversion systems (WECS) and because of the problems of the fixed speed wind generators, variable speed wind generators are preferred to them. One of the variable speed generators is the dual stator winding induction generator (DSWIG). This type of generator in comparison with a doubly-fed induction generator (DFIG), the most common type of variable speed generator among wind turbines, has robust structure and less maintenance cost due to the elimination the brushes and slip rings . Because of the structure of the squirrel cage rotor, it is also simpler to construct the brushless doubly-fed induction generators (BDFIG) with a nested-loop rotor structure. This paper introduces the variable speed wind energy conversion system which utilizes the dual stator winding induction generator to supply the autonomous AC load as independent of the grid. Then, the appropriate topology, by using power electronic converters and appropriate control methods, is designed. For the power regulation and voltage stabilization with the desired amplitude and frequency, controlling electronic power converters are presented under the conditions of load and wind speed changes. To validate the understudy system and the desired control methods, the simulation results at SIMULINK environment in MATLAB softwareare presented.
