도시철도 운행에너지 개선기술에 관한 연구

초록

Government has been encouraging to save the energy nationally since 15th Sept. in 2011 when is occurred the electricity crisis in Korea. And regulation related the energy is tightened, e.g., electricity cost increasement and the period broadening of the peak electricity demands. Railway is typically energy consumption industry at the use stage. In the rapidly changing circumstances of energy policy, various researches are in progress but most researches are focusing on the electric facility in railway system. From the current electricity consumption statistics, the consumption ratio of the railway running energy is higher than that of facility. The ratio is 65% vs. 35%. According to the energy consumption ratio, systematic control technology of the running energy of the railway vehicle is required. In this research, on-line energy control and saving technology of the railway vehicle at the running stage is suggested.
