This thesis, developed as part of a collaboration between Infra.To and Politecnico di Torino, describes the development of a web application for the modelling and simulation of the Turin tramway network electrification system. The destination of the work is two-fold: on the one hand it should enable network operators to perform quantitative analyses of the system, in order to support both maintenance and planning phases by studying hypothetical scenarios. On the other hand, it should contribute to a research project of the Department of Energy "Galileo Ferraris" of Politecnico di Torino that aims to provide a comprehensive monitoring of the energy flows in the city.
