Abstract

The evolution of public transportation exhibits high potential nowadays due to the consistent demand of clean transportation with low pollution rates. Therefore electrified railway systems become viable with their environmentally friendly properties. This study aims to improve the efficiency of DC power supplied railways via employing energy storage technology to maximize the overall energy efficiency. A flywheel energy storage system has been applied to store the regenerated energy during braking instead of dissipating it in the form of heat; then this stored energy can be used to compensate system disturbances and imbalance periods. A 75 kW/90 kJ squirrel cage induction machine based flywheel energy storage system is dedicated with a 600 VDC electric railway system to control the energy between the traction motor and the DC bus. The proposed control strategy is simulated using MATLAB/Simulink and simulation results have been shown. An experimentally FESS is built to support the study by experimental results. © 2013 IEEE.
