Abstract
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.
