Estimation and measures of voltage drop occurred by increasing train sets in high-speed railway

고속철도 운행 증가에 따른 전압강하 예측 및 대책

The more feeding distance of substation is long and travel vehicle increases in feeding section, power supply leaches 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 and the effects installing compensation facility in case of impossible extended feeding is examined.
