Abstract
A doubly fed induction generator (DFIG) speed control system is provided. The system includes a wind turbine and a wound rotor induction generator connected to the wind turbine through a drive train system and to a power grid. The system further includes a back-to-back voltage source converter (VSC) with a rotor side converter (RSC) and a grid side converter (GSC). The RSC is connected to the wound rotor induction generator and the GSC is connected to the power grid. A wind profile sensor measures a wind profile and a VSC controller provides control to the RSC and the GSC. The VSC controller applies a nonsingular fast terminal sliding mode control (NSFTSMC) scheme at the RSC at least partially based on the received wind profile to stabilize a rotor speed of the wound rotor induction generator.
