The invention discloses an urban
power grid fault quick
response system and method, and the
system comprises a power dispatching center, a plurality of mobile energy stations and a plurality of power failure partitions, each power failure partition comprises an
encryption terminal, the power dispatching center comprises an
encryption and decryption terminal, and the mobile energy stations comprise decryption terminals. The fault request information of the power failure partition is encrypted by the
encryption terminal and then sent to the encryption and decryption terminal of the power dispatching center for
verification and decryption, the dispatching instruction information of the power dispatching center is encrypted by the encryption and decryption terminal and then sent to the decryption terminal of the mobile energy
station for decryption, and the mobile energy
station executes a dispatching task according to the dispatching information. The mobile energy
station is selected according to the load demand, the driving path of the emergency power supply vehicle is formulated according to the traffic condition, the supply priority is determined according to the importance degree of the user, the safety and reliability of power supply are greatly ensured, and meanwhile, the safety and reliability of information interaction are further ensured by adopting a random key encryption method.
