Since electrical traction was introduced into rail traffic, it has always been the goal to convert the kinetic energy of the vehicles during braking into electrical energy and to feed that back into the railway electrical system. However, the great expense required for the vehicles, the lack of means for fast control and the small regenerative effect achievable heretofore have rendered difficult or have completely impeded the introduction of the regenerative brake on a wide basis. It is only recently that power electronics, with which any energy flow can be controlled and regulated arbitrarily by means of thyristors, has opened new possibilities for electrical regenerative braking in dc traction vehicles. This relates not only to the vehicle equipment but also to the power supply systems of the contact-line electrical systems. Thus, if new analyses are to be made of regenerative braking of electrical traction vehicles, then, besides the vehicle facilities, it is also necessary to investigate the problems of transmission and reuse of the fed-back energy.
