Rotor Fault Detection of wind turbine Squirrel cage Induction Generator using Teager-Kaiser Energy operator
This paper proposes the use of the Teager–Kaiser energy operator (TKEO) for the detection of a broken rotor bar (BRB) in a squirrel cage induction generator, which is used usually in wind energy systems. The TKEO is investigated using the non-stationary signals representation in the time/frequency domain by sensing the estimation of the instantaneous amplitudes and frequencies present on the st...
متن کاملGearbox Fault Detection of Induction Motor Using Stator Current Signal Demodulation
All of the induction motor faults are not detect in beginning and late perception of these faults will cause to very lose tolerance. Thus, fault detection and identification in induction motors have high importance for industrial activities. One of the most fault detection methods is motor current signal analysis. In this paper, we use a new method with title induction motor stator current sign...
متن کاملStator Current Harmonic Assessment of Induction Motor for Fault Diagnosis
This paper presents an assessment of motor current signature analysis for fault diagnosis of an induction motor. Single phasing fault has been considered and stator current harmonics are analyzed by assessing peaks and symmetry in harmonic spectrums both at normal condition and at fault condition. ‘db4’ is used for current signature analysis wavelet decomposition. A comparative observation is m...
متن کاملStator Core Fault Diagnosis in Induction Motor Using Adaptive Observer
This document presents a method of on-line fault diagnosis for iron core of induction motor stator based on adaptive observer. Due to the equivalent resistance is directly affected by the stator core fault, while the iron loss is considered in the series iron loss model of the induction motor, so we can determine the core fault state by identifying equivalent iron consumption resistance. In thi...
