On-Line Fault Detection and Localization in Three-Phase Induction Motor Drive Systems

Abstract

Induction motors are robust machines used not only for general purposes, but also in hazardous locations and severe environments. Although these are very reliable, they are susceptible to many types of faults. However, induction motor drive faults can be detected in an early stage, in order to prevent the complete failure of the motor drive and ward off unexpected production costs. In this paper, a simple diagnostic and detection method that allows the real-time detection and localization of single and multiple open-circuit faults in the voltage source inverter (VSI) for a three-phase induction motor drive system using just the motor phase currents, is presented. A model of the system is built using MATLAB/SIMULINK. Simulation results are presented showing the diagnostic method performance under distinct operating conditions.

Performance investigation of an advanced diagnostic method for SSTPI-fed IM drives under single and multiple open IGBT faults

“…Considering now the case of current-signal-based methods, one can detect the fault by working either: in natural frame associated to the measured currents as in Sleszynski and Nieznanski (2007), Sleszynski et al (2009), Park et al (2011), Estima and Cardoso (2013) and Wu and Zhao (2016); or in Concordia frame (Park frame) associated to the projection of the actual current in the equivalent two-dimensional (2D) frame used for the vector control of the IM with fixed basis vectors (with rotating vectors) as in Mendes and Cardoso (1999), Abramik et al (2003), Rothenhagen and Fuchs (2004, 2005), Zidani et al (2008), Estima and Cardoso (2011), Choi et al (2012), Mohamed et al (2013) and An et al (2015). …”
