Rotor Fault Diagnosis of SCIG-Wind Turbine Using Hilbert Transform

In this study, the possibility of rotor broken bar fault detection in squirrel cage induction generator (SCIG) based wind turbine using spectral analysis of the stator currents is investigated. The numerical method presented in this work is based on the Hilbert transform. It shows the possibility of improving the faults detection in electrical machines. The obtained results based on the proposed method are validated by simulation of an induction generators of 4 kW.
