posted on 2019-09-30, 10:18 authored by Andrea MariscottiAndrea Mariscotti, Jacopo BongiornoThe recordings of the pantograph voltage
and current waveforms across Italian and French
high speed railway lines (both Autotransformer 2x25
kV 50 Hz systems) are analyzed to estimate some
Power Quality indexes: harmonic spectra, harmonic
distortion, displacement factor and fundamental
component, in various rolling stock operating
conditions. These indexes, that define the electrical
interface between the rolling stock and the power
supply, are all relevant in order to assess both the
impact of the rolling stock on the network and the
suitability of the latter to ensure agreed performances
(electrical interoperability).
