<p>PROBLEM TO BE SOLVED: To provide an electric power feeding system which effectively utilizes regenerative electric power generated simultaneously on routes in different electric systems.SOLUTION: An electric power feeding system comprises: a first power converter 7 connected to a first electric power feeding circuit 1; a second power converter 8 connected to a second electric power feeding circuit 2 different from an electric system of the first electric power feeding circuit 1; a power storage device 9 connected in parallel to the first power converter 7 and the second power converter 8; and a power management device 10 which controls electric current output from the first power converter 7 to the power storage device 9 by a first current command and also controls electric current output from the second power converter 8 to the power storage device 9 by a second current command. The power management device 10 determines the first current command on the basis of a power feeding voltage 13 of the first electric power feeding circuit 1 and a charging rate 12 of the power storage device 9, and the second current command on the basis of a power feeding voltage 14 of the second electric power feeding circuit 2 and the charging rate 12 of the power storage device 9.</p> |
