Analysis of the optimal capacity and energy consumption of the dynamic braking resistor

Abstract

The motor block braking resistor of the high speed train is a railroad car component that causes the problems of the grinding and burning of the resistance steel and the cracking of the insulator while the train is running, and that damages the movement chopper, which affects the traction inverter. To remedy these problems of the motor block braking resistor, this research presents a new braking resistor model to help enhance the reliability of braking and energy saving, by calculating and analyzing the action cycle, optimal capacity, and energy consumption of the existing braking resistor model, and to obtain technological capabilities to secure stable functioning so as to enhance and guarantee the quality and life of the railroad car components in the course of designing the braking resistor. © 2012 Springer-Verlag.
