Study on Rail Electrification Systems and their Harmonic Distortion Issues

Due to the harmonics insertion from of the asymmetric electric engine, particularly high / elevated / sizable trains, torque ripple and chromatic resonant difficulties have been commonly documented in railway electrification systems (RESs). We investigated the imbalance and switching frequency caused by a neighborhood transmission system, as well as their effects and mitigation policies, in this work. The varying levels of deformation in the supplying program's input characteristics can present a hazard to the propulsion loads. The many
