The more feeding distance of substation is long and travel vehicle increases in feeding section, power supply reaches the limits. And if it exceeds the limit, it causes a serious trouble for train operation. Therefore, it is designed that the number of train increases constantly until 2030. So consistent power supply according to the increasement of vehicle in power system at present Seoul-Pusan high speed railway, regular operation in case of extended feeding occurring accidents in substation and the least headway scheduled at relevant section in case of impossible extended feeding is examined.
