Under, the capacity of the required supercapacitor to come into operation is that there is differences.Under the smaller departure interval, same traction section
Energetic interaction between lower adjacent train is frequent, leaves the regenerative braking feedback little energy that vehicle-mounted supercapacitor absorbs, required throwing for
The storage capacity for entering the vehicle-mounted supercapacitor used is small；With the increase of departure interval, the frequency of interaction of energy drops between train
