Supercapacitor Module Properties
Since, most of rectifiers in the metro network are unidirectional, the regenerative braking energy cannot be returned to the supply network and it should be wasted in the braking resistors or stored in an energy storage system. One way to store the braking energy is by using super-capacitors.
It was also found that although supercapacitors have high power absorbing characteristics, the state-of-charge significantly impacts on the charging current and the power absorbing capacity of a supercapacitor-based regenerative braking system.
At this point, 75% of the super-capacitor’s capacity can be used to store energy in braking times or restore it in accelerating times. Selecting a SOC lower than 0.25 leads to a voltage lower than 300 V which is not appropriate for power converter components as well as super-capacitors.
Today, super-capacitors are used in the transport systems as a mean to store energy and reuse it during short periodic intervals , , , , , . In a metro network system, the trains are accelerated and braked frequently.
