Current sensor fault detection, isolation, and reconfiguration for doubly fed induction generators / Rothenhagen, Kai in IEEE transactions on industrial electronics, Vol. 56 N° 10 (Octobre 2009)

Tubes à rayons X Résumé : Fault tolerance is gaining growing interest to increase the reliability and availability of distributed energy sources. Current sensor fault detection, isolation, and reconfiguration are presented for a voltage-oriented controlled doubly fed induction generator, which is mainly used in wind turbines. The focus of this analysis is on the isolation of the faulty sensor and the actual reconfiguration. During a short period of open-loop operation, the fault is isolated by looking at residuals calculated from observed and measured signals. Then, replacement signals from observers are used to reconfigure the drive and reenter closed-loop control. Laboratory measurement results are included to prove that the proposed concept leads to good results.

Doubly fed induction generator model-based sensor fault detection and control loop reconfiguration / Rothenhagen, Kai in IEEE transactions on industrial electronics, Vol. 56 N° 10 (Octobre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 10 (Octobre 2009) . - pp. 4229 - 4238 Titre : Doubly fed induction generator model-based sensor fault detection and control loop reconfiguration Type de document : texte imprimé Auteurs : Rothenhagen, Kai, Auteur ; Fuchs, Friedrich Wilhelm, Auteur Article en page(s) : pp. 4229 - 4238 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Doubly  fed  induction  machine  Fault-tolerant  control  Observers  Sensors Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Fault tolerance is gaining interest as a means to increase the reliability and availability of distributed energy systems. In this paper, a voltage-oriented doubly fed induction generator, which is often used in wind turbines, is examined. Furthermore, current, voltage, and position sensor fault detection, isolation, and reconfiguration are presented. Machine operation is not interrupted. A bank of observers provides residuals for fault detection and replacement signals for the reconfiguration. Control is temporarily switched from closed loop into open-loop to decouple the drive from faulty sensor readings. During a short period of open-loop operation, the fault is isolated using parity equations. Replacement signals from observers are used to reconfigure the drive and reenter closed-loop control. There are no large transients in the current. Measurement results and stability analysis show good results.
