직류 도시철도 시스템 시격에 따른 피크전력 및 전압변동 분석

초록

This paper dealswith power integration of large urban railway systems to improve regenerative energyutilization. Current regenerative energyutilization is lowbecause there is no special plan for using this energy. If the railway system is integratedwith other railwaysystems, the efficiencywill be improved. In this paper, topre-operationof interconnectionof two railway system, analyze simulation of railway system to verify the peak power consumption and voltage stability at different headway. The case study of seoul metro lines were performed. In this paper, In thiswork, the railway systemismodelledbyusingCompaqVisual Fortran.
