Abstract
Nowadays wind is considered as one of the most important alternative sources of energy. It’s featured as being practically free and having no negative impact on environment. Because of increasing of the fuel-energy crisis an accent in using wind energy has quickened recently. An article given includes information about the structure of a wind turbine. The squirrel cage induction machine is considered as a generator. The model of an autonomous asynchronous generator has been built taking into account the nonlinearity of a magnetic circuit. Also it’s presented the model for plotting speed-torque characteristic of an asynchronous machine. Simulation has been made in Matlab Simulink.
