The invention discloses an energy storage type traction system, a control method thereof and a rail traffic tool. The energy storage type traction system comprises a power grid power source, a traction transformer, a four-quadrant rectifier, an intermediate direct current unit, an auxiliary inverter, a traction inverter, energy storage equipment, a bidirectional AC/DC converter, a first control switch, a second control switch, a third control switch and a fourth control switch. The energy storage equipment, the third control switch and a secondary winding of the traction transformer are connected; the output ends of the energy storage equipment, the fourth control switch and the intermediate direct current unit are connected, and the output ends of the energy storage equipment, the second control switch, the bidirectional AC/DC and the auxiliary inverter are connected, so that the energy storage equipment is charged in the forward direction and the auxiliary load is supplied with power in the reverse direction; the energy storage equipment and the auxiliary inverter are connected in the same circuit, and the rated insulation voltage of the energy storage equipment does not depend on the voltage grade of the traction intermediate direct current unit, so that miniaturization and light weight of the energy storage equipment or improvement of the power and voltage grade of the traction converter are facilitated.

    本发明公开了一种储能式牵引系统及其控制方法和轨道交通工具,包括电网电源、牵引变压器、四象限整流器、中间直流单元、辅助逆变器、牵引逆变器、储能设备、双向AC/DC变流器、第一控制开关、第二控制开关、第三控制开关和第四控制开关;将储能设备、第三控制开关、牵引变压器的次级绕组相连;将储能设备、第四控制开关、中间直流单元的输出端相连,将储能设备、第二控制开关、双向AC/DC、辅助逆变器的输出端相连,实现了正向对储能设备充电又能反向为辅助负载供电,同时储能设备与辅助逆变器连接在同一电路中,储能设备的额定绝缘电压无需依赖牵中间直流单元的电压等级,更利于储能设备的小型化与轻量化或牵引变流器的功率与电压等级提升。
