Network calculations Yarra Trams

ENOTRAC was tasked by Yarra Trams, the operator of the tram network in the city of Melbourne (Australia), to model their network with the simulation-tool FABEL. The Melbourne tram network is one of the biggest in the world. The point of the investigation was to determine possible weaknesses of the tram network energy supply, and to identify potential optimisation. A sensitivity analysis revealed the influence of individual parameters on the power supply, such as the rectifier spacing, contact wire resistance, or the slope of the line. The project was divided into several phases. First, three lines were modelled in detail and evaluated. Lastly, the sensitivity analysis was carried out, where the entire tram network was modelled and evaluated. A validation of the model using on-site measurements confirmed the results and conclusions.
