Abstract

Auxiliary power supply system is an important component of traction trains. Voltage fluctuation of auxiliary power supply system is a nonnegligible factor threatening the safe operation of traction trains. This paper based on electric spring theory aims to stabilize the voltage of the critical load in traction train auxiliary power supply system. And a method of stabilizing the voltage of the critical load with the electric spring is proposed. In this paper, a simulation model is established by Matlab/Simulink to verify the validity of the electric spring. The simulation results show that the electric spring can effectively mitigate the voltage fluctuation of the critical load, ensuring the critical load to work with a steady voltage.
