This paper introduces a new diagnostic technique for the detection of incipient electrical faults in Doubly Fed Induction Machine for wind power systems. In the considered application, the rotor is supplied by a static converter for the control of active and reactive power flows from the generator to the electrical grid. A new diagnostic method based on the rotor modulating signals pre-processing...
This paper investigates a new monitoring and diagnosis technique for the detection of electrical rotor faults in (DFIM) Doubly Fed Induction Machine for wind power systems under time-varying conditions. A new approach based on Frequency Sliding (FS) and Discrete Wavelet Transform (DWT) is here proposed in order to detect rotor faults dynamically over time. Moreover, a cyclic quantification of the...

The paper introduces a new monitoring and diagnostic technique for the detection of rotor electrical faults in Doubly Fed Induction Machine (DFIM) for wind power systems. Operating in aggressive environments, with plans onshore or offshore, the detection of anomalies at an incipient stage is a crucial step to decide about the operating continuity of the machines. Discrete Wavelet Transform (DWT) with...
This paper investigates the impact of the control system bandwidth on the detection of incipient faults in doubly fed induction generators used in wind turbines. In this application, the rotor is supplied by a static converter for the control of active and reactive power flows from the generator to the electrical grid. The Impact of the closed loop control system cannot be neglected when the detection...
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...
