“…However, the online detection of the USV is not very much reported. In [20], a method based on the Goertzel algorithm was used to extract some spectral components from the Park's vector and the motor vibration to detect an incipient USV. In [21], a technique called symbolic dynamic filtering (SDF) was proposed for the early detection of stator voltage unbalance in three-phase induction motors.…”

Three-phase induction motors (IMs) are the main workhorse in industry due to their many advantages as compared to other types of industrial motors. However, the efficiency and lifetime of IMs can be considerably affected by some operating conditions, in particular those related to unbalanced supply voltages (USV), which is quite a common condition in industrial plants. Therefore, early detection and a precise severity estimation of the USV for all working conditions can prevent major breakdowns and increase reliability and safety of industrial facilities. This paper proposes a reliable method allowing for a precise and online detection of the USV condition, by monitoring a pertinent indicator calculated using the voltage symmetrical components. The effectiveness of the proposed method is validated experimentally for several different working conditions, and a comparison with other indicators available in the literature is also performed.

“…It requires a long calculation procedure. Imbalance is also characterized by the appearance of an opposite frequency component at −50 Hz in the current vector spectrum and stator voltage (Moussa et al, 2014) or at the fundamental frequency. This imbalance produces a spinning field opposite to the field produced by the direct sequence which affect the developped torque by the induction motor.…”

Wind turbines are widely exploited throughout the world. The availability and reliability of offshore wind turbines are asking to impose a constant maintenance strategy. In this work, we propose a method that allows filtering the signal of the frequency inverter that feeds the yaw drive used in wind turbine. The redundant information is eliminated via discrete wavelet transform and empirical modal decomposition. The two types of faults are detected from the envelope of the Hilbert transform. The magnitude imbalance detection is carried out in the time domain. The root mean square values of the envelopes of the threephase system have a good indicator for the fuzzy system to evaluate the severity of the defect. In the frequency domain, the signature of the broken bar fault is located in the low-frequency bandwidth. The harmonics appeared in the spectrum sensitive in amplitude and frequency to the variation of load. Experimental results have demonstrated the accuracy of the proposed method.
