  This paper proposes an integral sliding mode direct power control (ISM-DPC) strategy for brushless doubly fed induction generators. Two widely applied control strategies are available for this type of generators: hysteresis-based direct power control and vector control. Direct power control suffers from high power ripples and current distortions produced by variable switching frequency. Moreover, the tuning issues of PI controller, which are highly reliant on machine parameters and operating conditions, and necessity of a phase-locked-loop for frame alignment are accounted as limitation of these methods. The proposed integral sliding mode strategy directly controls active and reactive power to provide fast dynamic response and zero steady-state error. This method is developed in the control winding reference frame to avoid the application of PLL. A large-scale brushless doubly fed induction generator (BDFIG) is simulated to validate the effectiveness and robustness of the proposed ISM-DPC method in comparison with widely applied methods, vector control and direct power control.

  The brushless doubly fed induction generator (BDFIG) is one of the main members of doubly fed electrical generators which has come close to commercialization in recent years. This generator has some of outstanding features of squirrel cage induction generator and conventional synchronous generator, and at the same time, it requires a partially rated converter. One of the major challenges in the evolution of this generator is the problem of controlling it and the necessity of having a suitable and efficient controller to stabilize the generator in the operating speed range. Therefore, in this paper, a comprehensive vector control scheme based on nonlinear control methods is proposed. Accordingly, a reference model controller fulfills the control of rotor speed. In addition, for simultaneous control of reactive power and torque, a combined approach based on sliding mode and PI controllers are used. The simulation results show in presence of the mentioned control structure, the dynamic response of system in different conditions such as change of mechanical input power and reference speed variation is much more appropriate than when a linear controller is used.
