6 FAQs about [Metro regenerative braking energy storage]
What is regenerative braking energy recovery system?
Before connecting the regenerative braking energy recovery system, when a metro train is in traction operation, E tr is provided by the traction substation. When a metro train is in regenerative braking operation, part of the braking energy is returned to the DC bus, and part of it is consumed by the braking resistance of the train.
Can a hybrid regenerative braking energy recovery system stabilize Metro DC traction busbar voltage?
In order to fully utilize the regenerative braking energy of metro trains and stabilize the metro DC traction busbar voltage, a hybrid regenerative braking energy recovery system with a dual-mode power management strategy is proposed. Firstly, the construction of the hybrid regenerative braking energy recovery system is explained.
Do Metro Trains use regenerative braking?
Metro trains experience frequent regenerative braking during operation, producing a significant amount regenerative braking energy [4, 5].
Does regenerative braking save energy?
Regen-erative braking has been widely applied on electric trains, particularly in metro transit systems. Compared with trains with only pneumatic braking, studies show that the use of regenerative braking on metro trains can provide energy savings of 10% to 45%, depending on sys-tem characteristics (1).
How regenerative braking is used in electric trains?
In case of electric trains, the excess energy of vehicle regenerative braking is mostly wasted as heat. Instead of an instantaneous waste, a later re-use of this energy requests the adoption of an electric storage system.
How regenerative energy can be stored in a metro train?
If there is a high power demand from the low-voltage loads, regenerative energy produced by the metro train could be preferentially fed back to the AC 400 V grid to meet the demand. On the other hand, if the demand is low, the energy could be stored by a device such as a supercapacitor.
