Study on squeezing control of regenerative power on Yamanote Line Series E231 train in DC traction power supply system

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, a simultaneous measurement between a Yamanote Line Series E231 train and the adjacent substations was conducted. From these measurements, the correlation between squeezing control of regenerative power in the train and behavior of the substations was confirmed. Also, to consider minimizing the total squeezing control of regenerative power we studied the total of squeezing control of regenerative power from the data at the substations.
