Summary
The improvement of electric locomotive's traction properties occurs due to using of brushless traction motors and improving their control systems. The use of brushless traction motors (three-phase AC induction motors) complicates the system of electric power converting and is characterized by a high degree of interaction and mutual influence of processes between the elements of the traction drive. This requires in-depth research at the design stage, it is necessary to study the interconnected electro-mechanical processes arising at various modes of functioning, and to find optimal control algorithms [1]. The use of computer models of electromechanical processes in traction drive takes on particular significance during the control system elaboration This allows forming its structure and parameters in parallel with the development of the rest of the equipment. There is an opportunity to take into consideration the revealed features of the traction drive functioning during the designing of its individual elements or entire subsystems
