[0019] figure 1 A schematic configuration of the emergency travel system according to the first embodiment is shown. The emergency travel system includes: a vehicle control device 100 that supplies electric power to a motor 10 that drives a railway vehicle; and a power conversion device 200 that supplies electric power to an electrical device 20 of a railway vehicle such as an air conditioning system or a lighting system. This emergency travel system is provided for continuously supplying electric power to the motor 10 and the electric device 20 even in a state where the supply of electric power by the trolley wire 1 becomes impossible due to a power failure or a pantograph off-line, wherein when the overhead The pantograph goes offline when the contact state between the wire 1 and the pantograph 2 cannot be maintained due to vibration of the vehicle or the like.
[0020] The vehicle control device 100 includes a high-speed circuit breaker 102 , a charging circuit 104 , an in...
