Systems Approach to the Analysis of Electromechanical Processes in the Asynchronous Traction Drive of an Electric Locomotive
Abstract Improving the efficiency of modern electric locomotives calls for new approaches to design. At the design stage, the dynamic properties of the mechanical parts and the behavior of electrical equipment and control systems in various modes of operation (e.g., start and acceleration, traction regime, coasting movement, wheel-slide protection) must be evaluated. These objectives can be achieved using a systems approach to the analysis of electromechanical processes in asynchronous traction electric locomotives. To solve these problems, a complex computer model based on the representation of an traction drive with Alternating Current (AC) induction motors as a controlled electromechanical system is developed. A description of methods applied in modeling of traction drive elements (traction motors, power converters, control systems), as well as of mechanical parts and of “wheel–rail” contact, is given. The control system provides individual control of the traction motors, and focuses on the results of dynamic processes modeling in various modes of electric locomotive operation. Mathematical modeling methods were used to investigate the dynamic characteristics of the electric locomotive EP20 under various conditions: movement in a straight line, in curves and in the turnouts.
