Study on Vector Control for Double-Fed Induction Machine with Stator Windings Short Circuited

Starting up and/or low speed operations are imperative for double-fed induction machine (DFIM) in DFIM-based driving system or DFIM-based wind turbine system under low speed wind conditions. Compared with others, the rotor-side driving control strategy with stator-winding short circuited can operate DFIM, without extra equipments, at low speed very well. The operation theory is analyzed, based on which the equivalent circuits and the corresponding mathematical models are presented and discussed. According to the models, built in the paper, vector control for rotor-side driving control strategy is proposed, with which, the decoupled control between the torque current component and the excited current component of DFIM rotor currents is achieved. As result, the dynamic and stable control performances of DFIM-based systems are improved. To validate the proposed control strategy, a 2MW DFIM-based driving system is simulated.
