연장급전 조건의 전압강하 현황 및 보상방안 검토

초록

This paper presents prediction of voltage profile under extended feeding condition. The prediction is performed by simulation. The simulation also includes results of present train schedules and assumed one for future. The assumed schedule is based on present circumstance. In addition, This paper presents two alternatives about countermeasures against voltage drop. The one is installed capacitor bank in substation. and the other one is installed in sectioning post. Two alternatives are investigated the effect respectively by simulation. Keywords : Traction power supply system, Extended feeding, Voltage drop, Countermeasure
