Özet
In this study, the use of instantaneous symmetrical components (ASB) for mechanical fault detection in an inverter controlled induction motor has been investigated. The proposed fault detection method is based on the calculation of the ASBs of the stator currents. The spectral density (PSD) of the positive sequence power component is estimated using the least squares method (EKY). Then, mechanical fault detection is performed using the generalized likelihood ratio test (GLRT). Modulated signals from both stator currents and closed-loop have been shown to be successful in detecting faults. The simulation results in the analytical model of aninverter controlled induction motor give the effectiveness of this proposed approach. This results in an effective fault detection method for an induction motor load torque oscillation.
