Abstract
A locomotive regenerative electric energy feedback system with an ice melting function, comprising two regenerative electric energy feedback devices (1). A direct-current side positive electrode of the regenerative electric energy feedback device (1) is connected to a positive electrode bus of a subway traction network, wherein the positive electrode bus is connected to an uplink contact network and a downlink contact network respectively via a first switching switch (4) and a second switching switch (5). A direct-current side negative electrode of the regenerative electric energy feedback device (1) is connected to the downlink contact network or the uplink contact network via a third switching switch (2), and the direct-current side negative electrode is connected to a negative electrode bus of the subway traction network via a fourth switching switch (3). Further disclosed is a control method corresponding to the system. In the system and method, the ice melting function on a contact network circuit between two traction stations is achieved by means of switch switching and a control method for adjusting the regenerative electric energy feedback devices, and an original regenerat…
