Abstract :
In this paper, some application examples of energy saving measures in two representative Japanese railway companies, mainly in d.c. electric traction power supply system, are introduced. The effect of electric energy storage systems installed to substations is mentioned especially. In addition, it is also described about the potential of regenerative braking energy, which will be able to be utilized by installation of energy storage systems or other measures.
