Abstract

A method for suppressing an electric locomotive from generating high-order harmonics after axle isolation, a control system and an electric locomotive are disclosed. When any axle is isolated, phases for rectifiers of the remaining working axles are redistributed. The present disclosure redistributes the phases for the remaining axles after the axle isolation, effectively suppressing the high-order harmonics generated during cutting-axle operation, and thereby effectively avoiding the adverse consequences caused by the resulting increase in the voltage under the power supply arm due to the high-order harmonics.
