Zusammenfassung:	The invention provides a power grid topology based power system reliability calculation method. The method includes the following steps: determining input data of power grid topology; forming a minimal path set matrix of the power grid topology; outputting a minimum cut set of the power grid topology; and calculating reliability of a power system via the minimum cut set. The power grid topology based power system reliability calculation method has the advantages that in consideration of expanded faults caused by component faults of a disconnector, a busbar and the like, automatic search is performed to form an expanded fault failure table; multiple situations of source/sink, parallel branches and source and sink coincidence can be processed; programs can be configured according to practical situations, and a branch cut set, a node cut set and a branch and node hybrid cut set of the system are solved; and impact on the system due to expanded fault branches can be processed.
