[0060] The “topology analysis and status marking method for reliability evaluation of distribution network” of the present invention considers a series of action sequences of the distribution network after a failure, including fault isolation, distribution network reconstruction, fault repair, and network topology restoration. At each step, determine the status of each component and load and mark it accordingly, so as to determine the duration of power failure of each component and load after the fault occurs, and then accumulate its reliability indicators. Normally open switches are used when the circuit fails, The switch is temporarily closed to supply power to the circuit.
[0061] The term used in the present invention, "section": a group of feeder segments bordered by switches. If one of the feeder sections fails, the switch will act and the entire section will be isolated.
[0062] "Calculation bus": The physical bus must be the calculation bus; the nodes after the switch co...
