Induction Motor Traction Drive with Slipping Protection

Abstract:

The advantages and shortcomings of three-level voltage source inverters to be applied on locomotive traction electric drives are highlighted in relation to two-level ones. To protect wheels from slipping on rails, the control system is designed. The control system with protection from slipping uses system of direct torque control as the subordinated contour to produce control signals on voltage source inverter. The topology and principles of operation of both protections from slipping and direct torque control of traction induction motor with three-level voltage source inverters are described. The simplified structure of mechanical part of traction drive using basic and axle suspension is considered. The adequacy of designed control system is confirmed by means of Matlab, the results of mathematical modeling show a high convergence with the results of physical model of traction drive.
