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

Electrical traction refers to a system that uses electrical power for traction, such as railways, trams, trolleys, and other vehicles. The term "track electrification" refers to the type of power source that used power electric locomotive systems. It could be AC, DC, or a hybrid supply. This paper provides the comparative analysis of electric traction system with PI controller and PSO Optimization Algorithm
