열차제어 시스템 변경에 따른 직류 급전설비용량 최적화 분석

As power supply equipment is one of the most momentous factors in mass transport system which has a direct influence on the safe operation of trains, it should be secured of reliability as high as possible. Accordingly, in order to secure safe operation of the trains, capacity of the power supply equipment must be fully optimization and stabilized. In this review, the authors analysis to work out the optimal capacity of the power supply equipment when changing frequency of the trains is approached with the use of the simulation and the measured data. With reference to points at issue following an upgrade of train control system along with frequency shortening, this study presents practical alternative solutions on the problems occurring from DC supply system, based on the analysis of the simulation results and the case-by-case modeling approach.
