Dynamic regimes of double - Fed orthogonal asynchronous generator

The research was oriented to the problems of the double wound stator induction generator. Currently now, this generator is more and more considered in the technical literature, as an alternative to the synchronous generator. In the case of nonconventional generator systems, especially in the case of wind systems, the dynamic regimes of electrical generators show interest due to the random character of the torque produced by the wind turbine. This paper presents, based on the virtual orthogonal model, the simulation results of the considered generator in a specific wind generator regime, at a pulse variation of the wind turbine torque, that is similar to the one caused by gust changes of the wind speed. Based on the shown simulation results can be noticed the important variations of the machine current and torque at sharp change in the mechanical torque.
