Abstract:
Provided in an embodiment of the present application is a track auxiliary power supply control system. The system comprises a charger, a battery, a first power supply circuit, a second power supply circuit, an uninterruptible power supply circuit, and a power supply selective circuit. The first power supply circuit and the second power supply circuit are both connected to the charger, and the first power supply circuit and the second power supply circuit are switched by means of a power supply selection switch to supply power to a load. The uninterruptible power supply circuit is connected to the battery and continuously supplies power to the load when both the first power supply circuit and the second power supply circuit fail. Also provided in the present application is a control method for the control system. According to the application, DC busses BN1 and BN2 are combined into one DC bus and a BD bus is retained. The combined DC bus is then divided into two power supply circuits, which run through the whole train. The power supply selection switch is set on each coach. When one power supply circuit fails, the load of the present coach can be switched to another power supply circuit to enable the load operates normally.
