Energy Efficiency Improvement in DC Railway Systems: The State of the Art

June 9, 2021 Physical Science 0

In the context of worldwide concerns about decreasing CO2 emissions by minimising energy use and energy loss, this study focuses on the relevant subject of boosting energy efficiency in DC railway systems. In a detailed review, the main achievements in this complicated subject are synthesised and addressed, with a focus on the implementation and application of existing solutions on real case studies. As a result, all specific subtopics connected to energy efficiency are covered, beginning with power quality conditioning and concluding with the recovery of braking energy, which is lost in traditional DC-traction substations in huge amounts. Onboard and off-the-road storage devices for braking energy are explored and compared, with practical examples provided. The progress made in converting existing DC-traction substations into reversible substations with power quality improvement capabilities is then methodically evaluated by demonstrating the key findings of recent research on the subject. They include commercially accessible equipment as well as solutions that have been tested on experimental models. The findings of this comprehensive evaluation serve as a useful reference and source of support for research and development on energy-efficient traction systems.
