“…Much work has been published on modelled data, simulations and laboratory benches [18][19][20][21][22] but there is a lack of field measurement campaigns for current signature analysis. In the present work, an in-service DFIG wind turbine with potential gearbox faults has been analysed through electrically-based techniques.…”

Abstract. Operation and maintenance (O&M) of wind turbines is recently becoming the spotlight in the wind energy sector. While wind turbine power capacities continue to increase and new offshore developments are being installed, O&M costs keep raising. With the objective of reducing such costs, the new trends are moving from corrective and preventive maintenance toward predictive actions. In this scenario, condition monitoring (CM) has been identified as the key to achieve this goal. The induction generator of a wind turbine is a major contributor to failure rates and downtime where doubly-fed induction generators (DFIG) are the dominant technology employed in variable speed wind turbines. The current work presents the analysis of an in-service DFIG. A one-year measurement campaign has been used to perform the study. Several signal processing techniques have been applied and the optimal method for CM has been identified. A diagnosis has been reached, the DFIG under study shows potential gearbox damage.

Abstract. This paper introduces a new diagnostic techniquefor the detection of incipient electrical rotor faults in doubly fed induction Machine (DFIM) 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 by Frequency Sliding (FS) and Discrete Wavelet Transform (DWT) thereby is here proposed to detect rotor faults dynamically over time. Experimental and simulation results demonstrate the effectiveness of the proposed approach under time-varying conditions.

“…Recently, this task has been addressed by several researchers; some works aim to adapt MCSA methods for diagnosing wind generators, assuming steady state or limited and slow variations of the working load conditions as in [11], [12]. Nevertheless, these approaches cannot be considered as a general method of diagnostic, because they are subjected to a conceptual drawback: they apply a steady state based methodology to machines which usually undergo continuously variable working conditions.…”

“…Nowadays, the diagnosis through the I Diagnosis of Rotor and Stator Asymmetries in Wound Rotor Induction Machines under NonStationary Operation through the Instantaneous Frequency current monitoring is rarely used in wind power plants, but is recognized as a promising methodology. Moreover, the fault detection systems in electric motors based on monitoring electrical quantities and advanced signal processing tools have experienced an important development over the years [4]- [12]. This fact suggests the feasibility of developing analogous methods but applied to the machines used in wind generators.…”
