Discrete Time Block Control for a Double Fed Induction Generator Coupled to a Wind Turbine Emulator in the Presence of Grid Faults

چکیده
– In this paper, the authors propose a scheme to react to grid faults. This is based on block control technique using sliding modes. For normal operation the electric torque and the reactive power are controlled; when the fault is incepted the electric torque and the stator current are controlled. The wind turbine is emulated by a DC motor, which is controlled using a discrete time block controller which includes sliding modes. The applicability of the proposed scheme is tested via simulation.
