Current sensor fault-tolerant control of DFIGs using stator current regulators and Kalman filters

This paper presents a current sensor fault-tolerant control (CSFTC) strategy based on stator current regulator-based vector controller (SCR-VC) and Kalman filter for a doubly-fed induction generator (DFIG).

description This paper presents a current sensor fault-tolerant control (CSFTC) strategy based on stator current regulator-based vector controller (SCR-VC) and Kalman filter for a doubly-fed induction generator (DFIG). The SCR-VC regulates stator currents instead of rotor currents to achieve the decoupled control of active and reactive powers of DFIG, thus it does not require rotor current measurements. Stator current Kalman filters are then designed for the fault detection and isolation (FDI), and system reconfiguration under the faults of stator phase current sensors. Simulation studies undertaken on a grid-connected DFIG system reveal that the proposed CSFTC strategy is immune to rotor current sensor faults, and it provides strong fault-tolerance capability to stator current sensor faults.
