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.
