도시철도 혼잡도에 따른 회생제동에너지 변화추이에 관한 연구

In domestic research, there was no practical analysis to correlate between load factor and regenerative energy even if presenting idea to release congestion in metro. Therefore, this study is to try to define load factor and regenerative energy with academic background and prior researches and analysis change of regenerative energy to load factor by regressive analysis. The results of analysis were regenerative energy of common and express train increased at a rate of the higher load factor. But, recovery factor of express train is the higher than those of common relatively, it supplied regenerative energy with other trains as much as regenerative energy generated.
