There are several types of train braking systems, including regenerative braking, resistive braking and air braking. Regenerative braking energy can be effectively recuperated using wayside energy storage, reversible substations, or hybrid storage/reversible substation systems. This chapter compares these recuperation techniques.
To enhance energy recovery during braking, otherwise constrained by the need to have of other trains that at the same time are adsorbing power in the vicinity as in other typical railway applications [ 8 ], the utilisation of some energy storage has been foreseen. Several variants of storage systems can be considered:
Then, losses on the feeding line between the train and the storage are naturally canceled, while energy dissipated on-board resistors increases (from 2% up to 19%), because the available braking energy cannot be stored inside the storage, having a reduced sizing due the need to stay within the available volumes on-board.
A generic four-station railway system powered by one traction substation is modeled and simulated for the study. The results show that by applying the proposed method, 68.8% of the expected regenerative braking energy in the environment will be further utilized.
Before connecting the regenerative braking energy recovery system, when a metro train is in traction operation, E tr is provided by the traction substation. When a metro train is in regenerative braking operation, part of the braking energy is returned to the DC bus, and part of it is consumed by the braking resistance of the train.
