Abstract

QUIROGA, Jabid E.. Stator winding short-circuit fault detection in a permanent magnet synchronous motor (PMSM) using negative sequence current in time domain. Ing. Investig. [online]. 2009, vol.29, n.2, pp.48-52. ISSN 0120-5609.

A negative sequence analysis in time domain was applied to fault detection of permanent magnet synchronous motors (PMSM). The fundamental components of the motor terminal currents were obtained using a Notch filter, based on which the negative sequence components in time domain were then calculated; the negative sequence current constituted the stator winding short-circuit fault indicator. The negative sequence current also provided a qualitative evaluation regarding the severity of the fault. The proposed method promptly (< 22 ms) and reliably determined the stator winding short for different levels of severity in faults around and greater than 6.25% of the shorted phase. Experimental studies confirmed the proportional relationship between fault indicator and the level of severity. Using negative sequence current in time domain reduced computational cost and detection time compared to that in frequency domain. The proposed method could be extended to detect the shorted phase to improve monitoring. The method was validated online using a PMSM experimental setup with dSPACE and Matlab/Simulink environment.

Keywords : PMSM; fault detection; winding short-circuit; negative sequence current.
