Abstract

Suppressing the induction motor load oscillation of auxiliary converter in urban rail train is very important to ensure the quality of train power supply and the operation stability. Firstly, this paper analyzes the energy state of the auxiliary converter. Then, according to the mechanical characteristic curve of the induction motor, the unstable operating area of the motor is discussed. After that, a method based on the inverter output frequency compensation by detecting DC side voltage is proposed, resulting in controlling the energy state and suppress induction motor load oscillation. Finally, the effectiveness and practicability of the method are full verified by simulation and experiments.
