In view of such issues as high order harmonics anomaly in the power supply and distribution system at certain electrified railway traction in this paper

the issue of high order harmonic amplification for the traction load feature of the traction power supply and distribution system is analyzed through the test at site. The influence mechanism and factor to the resonance frequency and peak by the traction power line during the transfer of harmonic current is analyzed from the theory and

at the same time

the issue of harmonic current resonance amplification really existed in the traction power distribution system is proved through simulation of the parameters of the actual power distribution system. In this paper

the harmonic order anomaly mechanism for the electrified railway power distribution system is studied from such three aspects as test data

theoretical analysis and modeling and simulation so to provide the theoretical reference for the analysis and control of the electrified railway high order harmonic issue.
