Abstract

The possibilities to improve the energy indicators of dc electric trains with commutator traction motors are considered. The features of the power circuit structure implementing contactr–resistor starting and regulation of velocity in the traction and braking modes using rheostat and regenerative braking are shown. Ways to improve the power circuit and control system are proposed allowing increasing the energy efficiency of regeneration. The servo system of regenerative-rheostat braking and a mathematical model of the power circuit as applied to electric trains of ED4M series are developed, and the parameters of the braking resistors and method of regulation of their resistance in the mode of electrodynamic braking are determined. The quality of regulation of the regeneration current is determined by the proposed servo system ensuring stabilization of its value with the change of the overhead system voltage. The possibility of increasing the energy supplied to the power source in the mode of regenerative-rheostat braking by 3–6% is shown. It is recommended to use an artificial neural network to increase the operation speed and regulation accuracy allowing connecting the pulse converter control system and automatic braking control system.

Keywords: dc electric train regenerative-rheostat braking servo system pulse regulation
