A Study on the Energy Saving of Electric Railway System

전기철도에서의 에너지 절감 방안에 관한 연구 (조명등 및 전동차 운용 실측 분석)

Recently, since demands of energy saving and efficiency for electric railway system have been increased, the study for electrical operation system is needed. Therefore, case study according to increase of energy consumption, investigate the actual conditions of the operation of electric cars and lightings were analyzed. From the results therefore, it is found that the energy consumption of electric car is much more winter than summer, because heating for protect of the air pipe frozen. But the energy consumption of electric equipment of station office is much more summer than winer, the reason for air-conditioner. In future, according to outdoor air temperature and ridership, ,wish to study about system that can operate cold, block heater automatically.
