Electric Power Energy of Railway
Yasu OURA
Energy topics are frequently reported in newspapers. There are many problems such as short supply of crude oil, tecnology development of substitute energy, phenomena of global temperature rise by carbon dioxide, and unclear power generation by fast breeder. Targets in development of electric energy for railway are set to promote energy saving and rationalization, while research is progress aiming at electric power regeneration by electric power stockpile, peak cut in energy use, and reduction of feeding loss by higher feeding voltage. In this paper an outline of those developments and future trends is given.
