Description

technical field [0001] The invention relates to the field of energy storage equipment, in particular to a control system for a supercapacitor energy storage device. Background technique [0002] With the continuous development of rail transit and smart DC grid, it has become an inevitable trend to improve the energy utilization efficiency of rail transit and a more intelligent and stable DC grid. At present, part of the electric energy generated during the braking of domestic subway trains is absorbed and used by the vehicle equipment along the line, while the other part is consumed in the form of heating by braking resistors, or through mechanical braking (there is no braking resistor in subway trains) friction consume. In this way, a large amount of renewable energy is wasted in the form of heat, and at the same time, it also causes the voltage of the DC grid to fluctuate violently, which in turn poses a huge pressure on the DC grid for traction power supply.
