| Abstract |
Since opening of the high-speed railway in 2004, the rate of electrification has been increasing rapidly, and safety of the supply of AC railways has become very important. With the expansion of unmanned substations and digital substations, digital protective relays in feeding system need more attention. For accident prevention, it is necessary to develop accurate modeling and simulation technology for railway feeding devices of electric railway. And it is also important to educate and practice how to use the developed technology. The study will be usefully applied to the construction of new lines as well as existing lines. |
