Development of Analysis Model for Metro Railway DC Electric Power System

도시철도 DC 급전시스템 해석 모델 개발

The DC electric power system is the most important power source in a metro railway system. As metro railway system is expanded recently, the importance of DC electric power system is emphasized. Furthermore, the study for systemization and standardization of design and operation technique in DC electric power system is undergoing nowadays. For these studies, the development of standard analysis model for metro railway electric power system is required. In this paper, a standard analysis model for metro railway electric power system which is using PSCAD/EMTDC program is developed. The developed model is explained and the validity is shown by using the case studies.
