Methods for solving mathematical Laplace equation for calculating transient process of short-term braking mode of traction electric motors (KTR TED) of diesel locomotive of TE10 type

Abstract

In this article, ways to improve the device's efficiency for damping the field of a traction generator were considered. In the developed solution, containing a traction generator with an independent excitation winding, in parallel with which traction motors are switched on by power contacts that are switched off with a time delay, a power contact, switched from the first position from the controller, an excitation contactor, in the circuit of which the protection of the diesel generator set is connected in series, adjustable traction generator field damping resistance, connected in series in the conductive direction between the minus of the exciter and the traction generator field damping resistance, a diode, as well as excitation weakening contactors, switched on by the contacts of differential relays of the first and second stages for the current and voltage of the traction generator, connecting resistance power contacts parallel to the traction windings motors, and normally -open auxiliary contacts are connected parallel to the parts of the adjustable resistance to damping the field of the traction generator.
