PROBLEM TO BE SOLVED: To supply necessary and sufficient electric power to a feeder even when a power failure is generated by a method, wherein a mobile substation is moved through its own efforts up to a power-failure section, a generator and a substation part are operated by a motive-force source after the substation has reached a spot and the electric power is supplied to a feeder. SOLUTION: A mobile substation 1 is composed of a power-supply part vehicle P and of a substation-part vehicle T. The power-supply part vehicle P is provided with a generator 7, which supplies electric power to the substation-part vehicle T and with a diesel engine 9 by which the mobile substation 1 is moved through its own efforts and which drives the generator 7. In addition, the substation-part vehicle T is provided with a transformer 11 and a breaker 13, for power reception, which is installed across the generator 7 and the transformer 11, with a pantograph 15 by which transformed electric power is supplied to a feeder 107 and with a breaker 17 for power transmission, which is installed across the transformer 11 and the pantograph 15. Then, the mobile substation 1 is moved up to a power-failure section by using the diesel engine 9. After the mobile substation 1 has reached a spot, the generator 7 is driven by the diesel engine 9, and electric power is supplied to the substation-part vehicle T. As a result, required electric power can be supplied to the feeder 107 in the power-failure section. |
