Investigation of traction motor dynamic using computer simulation and method of mutual loading of two pair motors

This article presents a model of the physical and virtual test bed for traction equipment testing for mining dump trucks with a hybrid power plant. The physical test bed is represented by two pairs of traction induction motors, each of motors has a rated power of 350 kW. In each pair of motors, one performs the role of a traction motor, and the second - the role of a load. The both pairs are connected to the traction converter, with a nominal power of 800 kW. Also the article presents a simulation model of a hybrid electric traction unit in the MATLAB Simulink environment, in which the load corresponds to the actual driving conditions of the dump truck. The simulation results are presented below.
