In this study, the steady state characteristic of a Double Output Induction Generator (DOIG) driven by wind turbine operating at variable speed (shaft speeds in the subsynchronous and supersynchronous regions), constant frequency and constant voltage is investigated. Mathematical model on time domain is obtained for wind turbine and double output induction generator separately. A fuzzy logic controller is designed to obtain maximum total output power from the generator considering the restrictions of the system and the speed of the wind which is not constant. Finally, the simulation results and experimental results carried out in the laboratory are compared. This study shows that using an appropriate control strategy, maximum output power can be obtained from the wind tribune connected to DOIG.
