ELECTRIC BRAKING OF ELECTRIFIED URBAN TRANSIT VEHICLE

Problems connected with regeneration of electric energy are discussed and relationships are given for calculating the regeneration efficiency of electrified vehicles and the contact system, as well as the over-all regeneration efficiency. To increase the effectiveness of electric braking, electric traction motors of urban-transit vehicles must be operated in a regime realizing maximum braking capacity. Here in the high-speed range, for existing series of traction motors it is best to use a traction regime characterized by simultaneous variation in armature current and excitation current in a manner ensuring constant maximum voltage between commutator bars. For constant pairwise series-parallel connection of traction motors and follow-up resistive-regenerative braking at maximum permissible subway-car speed, regeneration efficiency is about 64% of the kinetic energy of the train, and is nearly independent of the load carried by a car.
