Detection of Interturn Short-Circuit Fault for PMSM With Simple Fault Indicator

IEEE Transactions on Energy Conversion, 2016
Interturn short-circuit fault is a kind of initial failure of the permanent magnet synchronous motor (PMSM) and serious consequences may be caused if it is left undetected. In this letter, a simple fault indicator is defined as the sum of the absolute values of amplitude differences between the stator currents, where the amplitudes of fundamental ...

Analysis of Fault Recorder Data for Short-Circuit Current in a 500kV Busbar Short-Circuit Accident

Advanced Materials Research, 2011
The three-phase short-circuit fault of the 500 kV busbar of Waigaoqiao No.2 Power Plant was described, and the fault recorder data was analyzed for short-circuit current. The RMS of short-circuit current decaying fundamental frequency component, DC component and the attenuation time constant was obtained by Fourier transform, extrapolating with the ...
