Abstract Through the analysis variable speed constant frequency doubly fed induction generator running characteristics, taking into account the instantaneous line-side converter current fluctuations,establish the precise mathematical model of DFIG. According to the vector control method,design a variable structure controller for DFIG no-load cutting-in control, caused grid voltage fluctuations and internal parameters of the perturbation is robust. After system simulation, proved the control system has good dynamic response and robustness; eventually verified through the application of back-to-back bench of the laboratory experiment the feasibility and effectiveness.
