Active load for testing the control algorithms of traction systems with induction motors of autonomous locomotives

Abstract

The accurate simulation of the load conditions that occur in the operation of battery-powered electric locomotives, mainly specific variable and dynamic loads in the whole range of operation, from standstill to maximum speed, is an essential aspect for testing the control algorithms of traction systems with induction motors. The attention of this paper is focused first on the presentation of a test bench dedicated to testing electric traction converter-induction motor assembly for autonomous vehicles. Then the presentation of the control algorithm for obtaining the load torque is approached followed by some experimental determinations.
