The energy absorption of regenerative braking of metro has always been the focus of energy saving, emission reduction and increasing efficiency in the field of urban rail transit. In this paper, the technical characteristics and appli- cation of different types of rail transit regenerative energy absorption device are compared and analyzed, the application of inverter feedback device specifically is simulated based on a real domestic metro line. The result indicates the regenera- tive braking energy of the subway train can be absorbed effectively via the device, while ensuring the DC voltage of the traction substation is in a security level. Moreover, the device can save energy, reduce the cost of subway operation as well as improve the economic benefit of urban rail transit system.
