About Direct Start of Induction Motor with Two-Stage Reactive Power Compensation as a Part of the Auxiliary Drive of Electric Locomotive

Abstract

The auxiliary electric drive of electric locomotives is often built on the basis of three-phase induction motors. In a number of auxiliary drive circuits, direct starting of motors is practiced, which is accompanied by significant starting currents. This imposes increased requirements on the installed power of the supply converter. A method for reducing starting and operating currents through the use of three-phase capacitor banks is considered. The simulation results are presented.
