Description

technical field [0001] The invention relates to the technical field of energy recovery, in particular to a regenerative braking energy management system and method for high-speed rail. Background technique [0002] At present, regenerative braking (also known as feedback braking) is given priority to the braking of high-speed railway trains. It is a braking technology used on electric vehicles. The kinetic energy of the vehicle is converted and stored during braking; instead of becoming Useless heat), that is, the traction motor is converted into a generator state to feed regenerative braking energy to the traction network. However, this braking method will cause problems such as an increase in the voltage of the traction network and low energy utilization. [0003] In order to solve the problem of regenerative braking energy utilization, the existing energy utilization methods include the dissipation type that absorbs the regenerative braking energy with a large resistor, t...
