Battery powered locomotive
A locomotive comprises a DC power bus, traction motors, batteries, and a charging source, but has no prime mover engine. Each traction motor includes armature and field windings connected in parallel across the DC power bus. The batteries provide power to the DC power bus when in a motoring mode, and receive power from the DC power bus when in a charging mode and a dynamic braking mode. The charging source is connected across the DC power bus to provide charging power to the batteries when in the charging mode. The traction motors also provide charging power to the batteries when in the dynamic braking mode. The power from the charging source is less than the power that would be provided by a prime mover engine. The charging source provides no power to the traction motors when in the charging mode.

The present invention relates to the field of energy storage technology, and in particular to a method for ground energy storage of regenerative braking energy on a long and steep slope. When a train is traveling on a downhill slope on a long and steep slope, a supercapacitor energy storage device is controlled to be charged to absorb the regenerative braking energy generated by the train, thereby reducing the contact network voltage and restoring the contact network voltage to a normal range. When the train is traveling on an uphill slope on the long and steep slope, the supercapacitor energy storage device is controlled to release electric energy and increase the contact voltage, thereby restoring the contact network voltage to a normal range. This ensures that the regenerative braking of the train will not fail, and improves the safety of train operation and the utilization rate of regenerative braking energy.
