Mathematical Model of the Electric Traction System of Quarry Railway Transport

Abstract

The AC electric traction system of the quarry railway transport has been considered. Ways to improve the system of the electric traction by using electric rolling stock with asynchronous electric drive have been proposed. The necessity of complex research of the electric traction system by mathematical modeling has been shown. A mathematical model has been developed, which includes the model of train dynamics, the model of power flows in electric rolling stock, and the model for calculation and determination of losses in traction power supply systems. Using the developed model will allow research of energy processes and optimize the operation of the electric traction system.
