Abstract
AbstractWhen multiple EMUs of high-speed railway are located in the same power supply arm, there is a phenomenon of harmonic interaction in the traction network. In order to analyze the influencing factors of harmonic interaction between high-speed railway EMUs, the harmonic interaction impedance matrix is calculated by establishing an equivalent model of harmonic transmission of the traction power supply system, and finally the harmonic interaction impedance matrix is obtained. Take a power supply arm of a high-speed railway as an example, use Matlab/Simulink to build a harmonic impedance model of the traction power supply system, analyzing the influence of the distance between the two moving workshops and the parameters of the vehicle-mounted high-pass filter on the harmonic transmission of the traction network has a certain reference value for reducing and avoiding the harmonic resonance of the traction network.KeywordsHigh speed traction power supply systemTransfer coefficientHarmonic impedance interaction modelHigh pass filter
