Since the current command IREF1 is generated and the converter control unit 46 that performs control by generating the charge / discharge current command IREF of the converter device 40 based on the charge current command IREF1, the inverter 50 is in a regenerative braking operation. When the load on the overhead line 1 becomes smaller than the regenerative power, the power storage device 60 is charged with power (regenerative power absorption) in conjunction with the generation of the suppression amount VDTELM accompanying the increase in the voltage detection value EFCV. Can do.

In some cases, the power absorption operation is not performed. In such a case, since the regenerative torque remains unnecessarily suppressed, wear of the mechanical brake shoe and waste of regenerative power occur.

Although the amount VDTELM is generated, an average value of the regeneration state signal included in the control command VC1 and the regeneration state signal included in the control command VC2 may be calculated and used as a regeneration state signal used for control.
- each converter 40 generates a charging current command IREF1 to the converter 40 and the power storage device 60 when the suppression amount VDTELM is generated in any of the plurality of inverters 50. Therefore, it is possible to avoid a case where only some of the converter devices are in an operating state.
- each inverter 50 transmits the regeneration state signal to an external integrated control device (not shown).
- the overall control device may transmit the regeneration state signal of each inverter 50 to each converter 40. In this way, the number of wires connecting each inverter 50 and each converter 40 can be reduced as compared with the case where each inverter 50 and each converter 40 are connected by wires.
- the embodiment of the present invention is not limited to the configuration described above, and is based on the regenerative state signal itself or the regenerative state signal, which is an amount indicating the regenerative torque suppression state or the regenerative power suppression state of each inverter 50.
