| description | The monitoring method proposed in this article is aimed at diagnosing Rotor Winding Asymmetry (RWA) faults in Wound Rotor Induction Machines (WRIM). Inspired by the principles of mechanical vibration analysis, this approach is based on the Residual Electrical Signal Extraction (RESE) strategy, which transposes the concepts of dynamic analysis to the electrical domain, exploiting the cycloergodicity of electrical signals rather than physical vibrations. The main challenge addressed by this method is the detection of faults, even at a very early stage, whether they appear as soon as the machine is commissioned or coexist with other internal conditions, even under light load. The RESE strategy has been validated by simulations and experimental tests on different configurations: healthy state, presence of defects, and several levels of severity. An IDSC (Incipient Defect Severity Criterion) indicator was introduced to quantify defect severity. The results show that the RESE strategy can effectively detect asymmetry defects of <10 % with a good level of reliability. The fact that the RESE strategy can be used off-line, without vibration sensors, simplifies its adoption in an industrial environment. |
