Abstract Fault tolerance is gaining growing interest to increase reliability and availability of distributed energy systems where, a model based current and voltage sensor fault detection, isolation and reconfiguration is presented for a voltage oriented controlled double Fed induction generator, which is mainly used in wind turbines. A bank of observers is used to provide residuals for the fault detection and replacement signals for the reconfiguration of the chosen observers and the fault detection via parity emulation and isolation logic are presented in detail during a short period of open loop operation, the fault is isolated when replacement signals from observers are used to reconfigure the drive and re-enter closed loop control. The concept is analised. There are no transients in the current. The installed Crowbar is not triggered. Measurement results are included to prove that the proposed concept leads to good results.
