직류 도시철도시스템 피크전력 관리를 위한 부하제어 기법 연구

초록

This paper deals with the techniques of load control of large urban railway systems to improve peak power management. Since current railway system calculate the basic rate of industrial electric charge through measure to substation’s peak power during certain headway, performing energy management by using controllable load could be efficient in railway power system. To find the realistic effect of energy management, the output data of Seoul Metro subsystems simulation by Compaq visual fortran are used in this paper. The verification process are performed Through PSCAD/EMTDC, The real system for the Seoul Metro lines, especially line 7 had been applied.
