Recent results on the Power Quality of Italian 2x25 kV 50 Hz railways

Jacopo Bongiorno, Andrea Mariscotti

Abstract

The 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).
