SIMULATION OF ELECTRIC TRAIN TRAFFIC IN THE PROCESS OF CONTINUOUS MODELING OF WORK OF 2Х25 kV ALTERNATING CURRENT SUPPLY SYSTEMS IN MATLAB / SIMULINK

The article is dedicated to reproducing the traction load in the process of continuous modeling of work of 2х25 kV power supply system in MatLab/Simulink framework. It suggests some options for adding user-defined Simulink blocks to simulate electric train traffic and run models of adjustable resistances, inductances and complex resistances with mutual inductive couplings. The method of continuous modeling of the process under the conditions of changing electric circuit configuration of traction power supply system is proposed. The examples of the implementation of simulation model for measuring performance indicators of 2х25 kV traction power supply system are given.
