“…Hence the necessity of induction generator monitoring and online diagnosis in order to resolve this problem. Among the online diagnostic methods [19], those based on the stator current such as the Park vector [20], [21] or its  ISSN: 1693-6930 spectrum [22], [23] or their combination [24]. In this part, an approach for detecting and characterizing three types of voltage dips is presented.…”

Voltage dips are brief but frequent disturbances that can be defined as the most important problem affecting all electrical grids, it cannot be completely avoided and represent the main priority for the industry. This study remains part of monitoring the quality of electrical energy's field. Its aim is to apply two approaches signals for improving the failure recognition in wind turbine conversion chain. One is based on the combination of spectral analysis of stator current by fast Fourier transform and Lissajous curves technique of grid currents. The second approach is based on the stator current analysis by discrete wavelet transform which is considered an ideal tool for this purpose due to its time-frequency localization. These defects diagnosis methods have shown their efficiency in detection, visualization and analysis of voltage dips in order to develop a control strategy for a wind turbine requiring continuity of its service despite the presence of voltage dips.

“…This coil has no conductive contact with the other phases but it is mutually coupled with all the other circuits on both the stator and rotor sides. This technic was applied previously for a wound rotor induction motor [15][16][17][18][19][20][21][22][23][24]25]. The position of this added coil is chosen that all electrical magnitudes can be measured such as voltage and flux.…”

“…After Applying the fourth order Runge-Kutta method to resolve numerically the differential matrix in (14), we obtain the current vector used to determine the auxiliary winding flux [15][16][17][18][19][20][21][22][23][24][25] = I sa + I sb + I sc + ∑ Nr =1 I r (19) The M saux , M raux are the stator and rotor auxiliary winding mutual inductances respectively. The flux in (19) lead to the auxiliary winding voltage expression: (20) In order to use the Lissajous curve for our model, the determination of the auxiliary winding voltage Park components is essential.…”

The development of electronic power components has allowed the increase of the induction machine performance. Indeed, monitoring squirrel cage induction motors driven through rectifiers and inverters has been a major concern. This paper presents a new method to diagnose the combination inverter-machine faults. This technic considers an auxiliary winding which is a small coil inserted between two stator phases. It is based on Lissajous curve of this auxiliary winding voltage Park components. For this purpose, modeling the electromechanical conversion chain is necessary. The focus will particularly be on modeling both the squirrel cage induction machine and the inverter in a non-defected case which is a reference. Moreover, the explicit expressions developed for the inserted winding voltage and its Park components will be presented. The simulation results show the effectiveness of the proposed method.

“…Figure 1 shows the coil position that forms an angle 𝜃 0 with the A stator phase and has no conductive contact with other phases but is mutually coupled with all the other circuits in both the stator and rotor sides. This approach was applied previously to a wound rotor induction motor [23]- [25]. The voltage of the auxiliary winding is the main key of this method.…”

<p>Condition monitoring and on-line detection have attracted several researchers in order to carry out an efficient diagnosis of machine failures. Therefore, the detection in early stage avoids system breakdown and reduce the maintenance cost. This paper presents a new diagnosic approach to detect the broken bars and broken end ring faults for a squirrel cage induction machine based on the fast Fourier transform analysis applied on a new signature as the voltage of an auxiliary winding. The auxiliary winding is a small coil inserted between two of the stator phases, the explicit expression of its voltage is presented. The signal is monitored in six faults cases under a different load level, the emergence of the fault frequencies changes for each kind of failure. The successfully simulation results obtained show the effectiveness of this approach.</p>
