Abstract
In order to improve the electromagnetic compatibility of the power supply systems of the metro with the supply network, it is advisable to organize a bi-directional exchange of energy between the source and the load. This article describes the structure of the metro power supply system with a four-quadrant DC drive based on a six-pulse bridge controlled rectifier, created its MatLab model, developed a control system of rectifier bridges with a separate operation algorithm, proposed an auto-regulation system based on a dual-circuit slave current-speed controller and calculated it parameters. When conducting a virtual experiment, it was possible to repeat schedule of movement of the electric train between the stations with high accuracy, to ensure the mode of energy recovery in the braking mode, to obtain the data necessary for calculating the energy performance of such a system. The resulting model will allow to investigate the energy efficiency of the metro power supply system at different operating modes and power line parameters.
