SIMULATION OF POWER SUPPLY FOR THE MOBILE COMPOSITION OF THE SUBWAY
The article is devoted to the simulation of power supply of the mobile composition of the subway. The paper presents the power supply scheme of the metro area, on the basis of which the model was developed in the SIMULINK package of the MATLAB program. As a load for converting devices of traction current, a submodel of the rolling stock car is used, which takes into account not only the parameters of the car, but also allows to simulate its control system and modes of operation. To study the transients in the model of the railway carriage, different states of control circuits of traction motors are simulated. The parameters of the traction motors in the model are calculated based on the load capacity of the car. Presented obtained as a result of modeling the dependence of the frequency of rotation, current and moment of the traction motor, as well as the speed and load characteristics of the car. Analyzed the simulation results and made recommendations for improving the power supply of rolling stock of the metro.
