Abstract

The paper introduces an advanced monitoring and diagnosis system for the detection of incipient electrical faults in doubly fed induction generators (DFIGs) used in wind generator systems. In this application the rotor power is supplied by a converter for the control of active and reactive power flow from the generator to the mains. The paper deals with a new diagnostic method based on the analysis of the rotor modulating signals. Simulation and experimental results confirm that the analysis of the spectra of rotor input modulating signals leads to an effective diagnostic procedure. The system is suitable to be easily embedded in the drive control system
