Traction substation power supply structure and control method thereof

The invention discloses a traction substation power supply structure and a control method of the traction substation power supply structure, and belongs to the technical field of electrified railway power supply. The primary side of a three-phase/two-phase transformer is connected to a three-phase power supply. The two phases of the secondary side are connected with two traction buses through twofeeding lines. A current transformer is connected in series to a working feeding line. Two alternating current sides of a single-phase alternating current-direct current-alternating current converterare respectively connected with one corresponding working feeding line of one of two working buses. The alternating current side of an alternating current-direct current converter of an energy storagedevice is connected with one group of working feeding lines of the working buses. The direct current side of the alternating current-direct current converter is connected with energy storage equipment of the energy storage dev
