Regenerative braking emergency stop system

摘要

In a regenerative braking emergency stop system, a substation includes: a rectifier transformer configured to transform AC power received from outside; a rectifier configured to convert the transformed AC power into DC power; and a switch disposed on an electrical path between the rectifier and a power-feed rail and configured to be in a closed state or an opened state; a simulated ripple transmitter configured to transmit a simulated ripple, the simulated ripple being an AC signal having a predetermined frequency; a superimposing circuit connected to the power-feed rail in parallel with the rectifier and configured to superimpose the simulated ripple transmitted from the simulated ripple transmitter on DC power outputted from the rectifier; and a relay device configured to allow the simulated ripple transmitter to transmit the simulated ripple when the rectifier is receiving power from outside and the switch is in a closed state.

1. A regenerative braking emergency stop system comprising: a substation; a power-feed rail fed with power from the substation; a running rail; and an electric vehicle configured to collect power from the power-feed rail and run on the running rail, the substation including: a rectifier transformer configured to transform AC power received from outside; a rectifier configured to convert the AC power transformed by the rectifier transformer into DC power; and a switch disposed on an electrical path between the rectifier and the power-feed rail and configured to be in a closed state or an opened state, the electric vehicle including a power collector configured to collect power from the power-feed rail, wherein
the substation further includes:
a simulated ripple transmitter configured to transmit a simulated ripple, the simulated ripple being an AC signal having a predetermined frequency;a superimposing circuit connected to the power-feed rail in parallel with the rectifier and configured to superimpose the simulated ripple transmitted from the simulated ripple transmitter on DC power outputted from the rectifier; anda relay device configured to allow the simulated ripple transmitter to transmit the simulated ripple when the rectifier is receiving power from outside and the switch is in a closed state, and the electric vehicle further includes:
a simulated ripple receiver configured to detect the simulated ripple from DC power collected by the power collector; anda controller configured to perform control to stop regenerative braking of the electric vehicle when having detected that the simulated ripple to be detected by the simulated ripple receiver has disappeared.
