Reversible Substation in DC Traction
Journal of Advance Research in Mechanical & Civil Engineering (ISSN: 2208-2379), 2015 In order to improve the green foot prints and also reduce the operational costs, it is currently standard practice to fit the Rolling stock of Metros railway units with regenerative dynamic braking systems. Thus, energy generated by a braking train can be reused by other accelerating trains.

RECTIFIER TRANSFORMERS IN ELECTRIC TRACTION SUBSTATIONS ‐ DIFFERENT DESIGNS
TRANSPORT, 2005 Electric traction in Poland is supplied with dc voltage which is obtained from the power grid via traction substations equipped with transformers and rectifiers. The paper gives the results of the investigation of different designs of these transformer‐rectfier sets ‐ namely, 12‐ and 24‐pulse systems.
