Abstract

The invention discloses a vehicle-mounted energy storage device and a method for an electric locomotive and an electric vehicle unit to achieve the purpose of avoiding the loss of traction force and speed of the electric locomotive and the electric vehicle unit when the phases are excessive, including: connecting in parallel with a traction converter The energy storage module on the direct current loop of the control module is used to receive the release energy control signal of the control module, work in the energy release working state, and provide the released energy to the traction converter during the energy release working state; and, receive control The stored energy control signal of the module works in the energy storage working state. During the energy storage working state, it stores the energy obtained from the DC circuit; the control module connected with the energy storage module is used when it is judged that it is in an excessive phase state. , sending a release energy control signal to the energy storage module; and, when it is judged that the electric locomotive and / or the EMU is under braking and / or the DC circuit voltage is too high, sending a stored energy control signal to the energy storage module.

Description

technical field

[0001] The invention relates to the field of electric locomotives and electric trains, in particular to a vehicle-mounted energy storage device and method for electric locomotives and electric trains. Background technique

[0002] At present, the world's energy is becoming increasingly tense, and energy conservation and consumption reduction have become a worldwide research topic, and energy recovery and reuse is an effective means of energy conservation and consumption reduction. With the development of high-speed and heavy-duty electrified railways in my country, railways, as a key energy-consuming industry, have great potential in energy recovery and reuse.

[0003] At present, the technical schemes commonly used to recover and reuse the energy generated by the braking of electric locomotives and EMUs are divided into two types: energy-consuming type and energy-feeding type. The energy-consuming scheme adopts the chopper and the braking resistor to cooper...
