Abstract :Recent interest in renewable energy sources is growing as a resource substitute for conventional energy and this led to increased interest in electric power can be obtained from the wind energy.With the rapid development in electrical generators used in wind turbines, induction generators have proven quality among the different types of electric generators used in this field.Based on that research aims to study the behavior of squirrel cage induction generatorinsert ignore into journalissuearticles values(two-speed); when linked with a wind turbine and study of using feasibility in this field.To achieve this purpose theoretical and practical study for induction generator two- speed were completed.Theoretical study contains a review of principles of operation of the machine , circuit equivalent and math equations, but practical study has been fulfilled on a laboratory model for two-speed induction generator driven by DC motor with variable speed .This study has been fulfilled when induction generator operates on both of speed and set speed at which it move from working as a motor to work as a generator for different values ​​of the excitation capacitors, and relationship between voltage of generator and speed is identified at different degrees of excitation.
Keywords : Induction Generator, Self Excitation, Reactive Power, Wind Energy
