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 ...
