Modeling and simulation of the 1500V metro supply network and vehicles

In order to utilize braking energy of metro vehicles at high recovery efficiency, it is necessary to research the metro supply network and metro vehicles. The simplified models of the metro supply network and vehicles are presented based on Simulink/SimPowerSystem via external characteristics. And the detail of some important modules are described in this paper. Meanwhile the character of the metro supply network, the accelerating and braking characteristics of the vehicles are given via simulation. Finally, the control strategy of the energy recovery system (ERS) is generalized. The simulation results are very similar to the data that the metro company offers. And the control strategy can drive the energy recovery system works well at high recovery efficiency.
