Fault detection and reconfiguration of the control loops of a Doubly-Fed Induction Generator are described in this paper. The stator voltage is measured as well as observed. During fault free operation, the measured signal is used for the field oriented control. In case of a voltage sensor fault, the faulty measurement is identified and the control is reconfigured using the observer output. Operation without measuring the stator voltage is possible. Laboratory measurements prove this concept.
