The invention provides a power distribution network integrated protection method merging line self-recovery, the method comprises the following steps: a step S10, when a power distribution network fails, removing fault through breaker operation, and obtaining fault information in the power distribution network in real time, wherein the fault information is an overcurrent information of a branch inthe power distribution network; a step S11, based on a net base structure matrix of the power distribution network, determining type and fault position through computation for corresponding matrix, and performing fault isolation; a step S12, based on an accessibility matrix, partitioning the power distribution network subjected to fault isolation, and recovering power supply of a passive region connected with an interconnection switch; a step S13, comprehensively considering line overload condition, load sensitivity and load importance degree to reconstruct the power distribution network. Byimplementing the power distribution network integrated protection method merging line self-recovery, better protective control performance with 'self-recovery' property can be obtained.
