A method and system for configuring regenerative braking energy recovery devices in urban rail transit provided by the present application, successively including the following steps: calculating a preliminarily configured capacity Pof a regenerative braking energy recovery device predetermined for the traction substation n, then obtaining an optimally configured capacity Qof the regenerative braking energy recovery devices; further, configuring the total number of the regenerative braking energy recovery devices; finally, configuring the type of the regenerative braking energy recovery devices. By reasonably configure the capacity and number of regenerative braking energy recovery devices in traction substations, the configuring method of the present application allows the regenerative braking energy generated by a train during braking to be completely absorbed, thus reduce the energy consumption of braking resistors. Meanwhile, the waste of idle regenerative braking energy recovery devices is avoided, and the acquisition cost of devices is reduced. By reasonably configuring the type of regenerative braking energy recovery devices, the deficiencies of a single regenerative braking energy recovery device can be avoided.

Method and system for configuring regenerative braking energy recovery devices in urban rail transit

The application discloses a hard-shell flexibly-packaged capacitor module and a system, including: a flexibly-packaged individual capacitor and fastening plates, including a first fastening plate and a second fastening plate being oppositely mounted and connected in clasped manner; and, supports including a first support and a second support being oppositely mounted and used for connecting the individual positive and negative tabs respectively; and the two supports and the two fastening plates being enclosed to form a closed structure for accommodating the individual capacitor. Individual capacitors and a silica gel insulator are assembled inside the fastening plates clasped with each other, i.e. a 'hard-shell' structure is provided for the individual capacitors; the hard-shell flexibly-packaged capacitor module is assembled as a whole, and multiple capacitor modules are connected in series or in parallel to form a required capacitor system, it is good in expansibility and easy to assemble.
