One kind of energy storage device and the OCS of the hybrid power supply system EMU

One kind of energy storage device and the OCS of the hybrid power supply system of EMU, characterized by: including traction transformer, the energy storage device, traction converter, traction motor, connected to the primary web is in contact with the pantograph and traction transformer, traction transformer with two secondary windings traction converter directly connected to the traction converter connected to the traction motor, storage means connected to the intermediate DC bus traction converter. The present invention can run on non-electrified lines and electrified lines, in the absence of catenary conditions, the braking energy is absorbed by the energy storage device to achieve the recycling of energy, reflecting the concept of green energy. There readiness and emergency rescue function when a particular rain and snow damage or catenary, the energy storage device may also be used as a mobile power source.
