Harmonic analysis caused by static converters of the railway high speed train and their impact on the track circuit

摘要

This paper deals with the study of the electromagnetic interference in railway field especially the disturbance generated by static converters such as the rectifiers and the inverters used in train propulsion system. The main study of this work is modeling and simulating the electrified railway propulsion drive equipped with two level NPC PWM inverter and rectifier for harmonics analysis and their impact on the railway signaling especially track circuit and proposing a solution to reduce the EM disturbance.
