ENERGY EFFICIENCY OF THE SUBWAY ELECTRICAL SUPPLY SYSTEM WITH ELECTRICAL ENERGY RECOVERY AT BRAKING

Purpose. The purpose of the paper is to assess the efficiency of the subway power supply system, which uses a four-quadrant DC drive with energy recovery in the supply network in the braking mode. Methodology. We have applied the theory of electrical circuits and mathematical simulation in Matlab pa...
