The invention provides a millisecond rapid reconstruction method and system for a power supply network after power network failure. A rapid network reconstruction master station collects power networkstate information from a transformer substation or a substation of a power plant, and compares the power network state information with a control strategy table containing possible failures; when itis monitored that an anticipated power network splitting failure occurs, switch-on pre-starting signals are sent to sub-stations corresponding to a plurality of network connection recovery circuit breakers; after the failure is cleared, the substations are used for identifying a clearing moment according to in-place information, and sending synchronous check switch-on signals to the correspondingin-place network connection recovery circuit breakers; and meanwhile, the master station independently monitors the clearing of the failure, sends backup synchronous check switch-on signals to the corresponding network connection recovery circuit breakers, and realizes the network reconnection of the split power network within 150ms after splitting on the basis of the above mechanism. The circuitbreaker which forms an electromagnetic loop network is disconnected after the interconnection of the power network is recovered.
