This paper studies such a problem that the faults recovery are independent and cannot be coordinated quickly in the transmission and distribution dispatching after the fault of the transmission network induces the outage of distribution network. Based on the power flow calculation and coordination information interaction of transmission and distribution, the transmission and coordination fault recovery strategy and the transmission and distribution coordinated power flow checking technology research are carried out. Through the integrated transmission and distribution model, the data of the real-time section of the transmission and distribution network is retrieved, and the coordinative fault recovery strategy is generated online, the coordination of the transmission and distribution network under the large-scale power outage failure are realized and the secondary fault caused by the coordination problem are avoided. The related demonstration application effectively improves the efficiency of the transmission and distribution network dispatchers in handling faults.
