Sensor fault detection and reconfiguration of the control loops of a doubly-fed induction generator is presented in this paper. The stator and rotor currents are measured as well as observed. During fault free operation, the measured signals are used for the voltage oriented control. In case of a current sensor fault, the faulty measurement is identified and the control is reconfigured using the observer output. Laboratory measurements prove this concept.
