TRACTION INDUCTION DRIVE FOR RAILWAY
Abstract

This paper presents the computer simulation and comprehensive dynamic processes of the induction motor with three-phase power inverter for traction application analysis. The control with proportional variation of amplitude and frequency of the power inverter are realized. The computer simulation of the considered traction drive on the basis of CASPOC software is executed. Computer CASPOC models of the induction motor, three-phase power inverter, control circuits and equivalent circuit of mechanical load are presented. Different control laws during acceleration of the traction induction drive and their influence on dynamic behaviour are researched. Transients of the traction induction drive with impulse and harmonic input voltage of the induction motor are compared. The procedure to design of the traction drive control with improving dynamic and power characteristics is offered.
