Abstract
The efficiency of the AC electric traction system is decisively influenced by the electric locomotives power factor. The power factor of electric locomotives with thyristor AC/DC converters is 0.8…0.84, when a recommended value is at least 0.95. The mathematical model of AC cargo electric locomotive 2EL5 traction electric drive (for traction mode) is developed to study ways to increase the energy efficiency of these electric locomotives. Based on the logical functions of the formation and distribution of pulses, a mathematical description of the AC/DC converter algorithm is obtained. This model is implemented by MATLAB. The mathematical model of 2EL5 traction electric drive allows investigating electromagnetic processes taking into account a voltage nonsinusoidality on the pantograph. The resulting graphs of voltages and currents correspond to the concept of electromagnetic processes in the traction electric drive of an electric locomotive, as described in previously publications.
