Abstract
Considering a DC traction system connected to the medium voltage AC supply network by means of Electric Supply Substations (ESSs) equipped with power static converters, it is worth in general to adopt statistical analysis for both interfaces to power distribution (AC supply and DC distribution). The structure of the system and the values of the parameters are variable (random variables), with a specific range of values and a probabilistic distribution. Attention is focused onto two problems: the power quality (low frequency conducted harmonics and resonance issues) of the AC supply interface and the DC distribution interface. Some results are obtained by means of statistical and probabilistic approaches. Software tools and code used to this aim are describe
