Brussels completes feasibility study to improve energy efficiency in tram network | UITP
Brussels Use Case leader of the ELIPTIC project, STIB, has completed a feasibility study to optimise the braking energy recovery in their tram network. The feasibility study was completed thanks to a thorough measurement campaign and the development of models and simulations of tram lines 7, 19 and 94.
One of the possible ways to reduce energy consumption in a tram network is to capture the braking energy that is generated by tramways during braking. In regular operation, a small share of this energy is reused by the vehicle auxiliaries, another part is sent back to the overhead line to power other vehicles. This latter share depends on the traffic conditions and characteristics of the network. The remaining energy, i.e., the part that could not be re-used, is dissipated in the tramway braking resistor.
