The invention discloses a novel locomotive multifunctional power supply device suitable for a high-power alternating-current electric locomotive and a fireless loopback power supply control method ofthe novel locomotive multifunctional power supply device. The power supply device is composed of a bidirectional DC power supply module (1), a lithium titanate battery pack (2), a bidirectional DC power supply module (3), a super capacitor module (4), a bidirectional DC power supply module (5) and an inverter power supply module (6). The power supply device can run in two directions, and can provide alternating-current and direct-current power supplies with various voltages for the alternating-current electric locomotive. When the power supply device operates from left to right, excitation power can be provided for power generation return of a traction motor of the alternating-current electric locomotive, and power can be provided for the alternating-current electric locomotive when the alternating-current electric locomotive operates without an overhead line system line; when the power supply device operates from right to left, the living power required by crew members can be providedfor fireless loopback of the alternating-current electric locomotive. The power supply device can improve the locomotive moving operation efficiency of the alternating-current electric locomotive without an overhead line system line, and can also improve the living conditions of drivers and passengers when the locomotive is returned without fire.

    本发明公开了适用于大功率交流电力机车的一种新型机车多功能电源装置及其无火回送供电控制方法。本电源装置,由双向DC电源模块(1)、钛酸锂电池组(2)、双向DC电源模块(3)、超级电容模组(4)、双向DC电源模块(5)、逆变电源模块(6)组成。本电源装置可以双向运行,可以为交流电力机车提供多种电压的交、直流电源。本电源装置从左至右运行时,可以为交流电力机车牵引电机发电回送提供激磁电力,还可以为交流电力机车在无接触网线路运行时提供电力;本电源装置从右至左运行时,可以为交流电力机车无火回送提供乘务人员所需的生活电力。本电源装置将可以提高交流电力机车在无接触网线路移车作业效率,也可以改善机车无火回送时司乘人员的生活条件。
