Study on train operation energy between commuter train and traction substations in a Japanese urban Railway

To reduce the environmental impact of the DC power system of the East Japan Railway Company (JR-EAST), it is important to have effective regenerative energy transfer from one train to another. In this paper, simultaneous measurements between the Yamanote Line Series E231 trains and the adjacent substations were conducted. From these measurements, the correlation between squeezing control of regenerative power in the trains and behavior of the substations was confirmed. Also, to consider minimizing the total squeezing control of regenerative power and maximizing the regenerative ratio, we studied the total of squeezing control of regenerative power and regenerative ratio on the trains from the data at the substations.
