Mathematical model of behavior of small wind power generators

A closed mathematical model of a small wind power generator is proposed where the electromechanical torque applied to the generator shaft is non-linear in current. The manifold of steady regimes is studied depending on parameters of the system. It is shown that increase of wind speed causes qualitative restructuring of this manifold, which leads to considerable change in behavior of the device. The influence of parameter describing the mentioned nonlinearity upon characteristics of the steady regime is studied. The influence of this parameter upon the range of external resistances is analyzed where the hysteresis of the output power takes place.
