In city track traffic engineering, the straight kind of drive for handing over variable voltage variable frequency is generallyd use, the mode of braking of vehicle is
Electric braking (regenerative braking) plus mechanical braking, in operation based on electric braking, supplemented by mechanical braking.Train in the process of running,
Since station spacing is shorter, frequently, braking energy is considerable for launch train, braking.Rule of thumb, subway regenerative braking generates
Energy is in addition to certain proportion (generally 20%~80%, according to the different and different of train operation density and zone distance) is by other
Outside adjacent train is absorbed and utilized, remainder will be consumed mainly in a manner of generating heat by the absorption resistance of train or by route
Absorption plant absorb.Past, the main absorption pattern of domestic city rail traffic are handled using resistance energy consumption absorption plant
Regeneration energy in train travelling process, this not only wastes energy, but also also increases the burden for interior air-conditioning blower unit of standing, and

Electric section has train to discharge stored electric energy when needing to take stream, and major defect is that bulky capacitor is arranged
Device group, and capacitor causes service life short because being frequently in charging and discharging state；The basic principle and capacitor of flywheel energy storage type are stored up
Energy type is the same, and only energy-storage travelling wave tube is fly-wheel motor, but since flywheel is in high speed rotation state, and flywheel mass for a long time
It is very big, therefore friction energy-dissipating problem is serious, flywheel working life is short；DC inverter when inversion feedback type is by vehicle braking at
Industrial-frequency alternating current and power grid in station are grid-connected, which is conducive to the comprehensive utilization of the energy, realize energy conservation.
Train braking energy storage devices in the utility model embodiment generally refer to above-mentioned capacitor energy storage type again
Raw braking energy absorption plant, can get up train braking energy storage, when train is again started up energy in feedback
To direct current net.
Energy-storage system experiment porch provided by the embodiment of the utility model can then set for these train braking energy storages
It is standby that a kind of working environment is provided, it, can be to these train braking energy storage devices in non-true train operational process
Performance and job stability are tested, and the efficiency of research and development of products and the exfactory inspection of equipment can be effectively improved, relative to
