The invention relates to a power supply restoration method for a power distribution network containing distributed power supplies. The power supply restoration method comprises the steps of firstly, monitoring the operation of the power distribution network in real time, processing operation information of the power distribution network, and searching an energizing area, a downstream de-energizingarea and an available tie switch between the two areas after fault isolation by using a Prim algorithm; secondly, transferring the load at the downstream of a faulty line to an energizing feeder linepreferentially through a feeder line with a tie switch, and performing power flow checking on the faulty line, performing load shedding if the faulty line does not satisfy the power flow checking; thirdly, restoring the power supply for the residual load losing electric power supply by adopting a mode of island operation, and performing island division by using a backtracking algorithm with a pruning function; and fourthly, carrying out reactive power compensation on nodes with power flow checking not satisfying voltage constraints, and forming a fault recovery scheme for the power distribution network. The power supply restoration method solves a problem of matching between the tie switch and the island in the power supply restoration process, thereby being conducive to sufficiently utilizing the distributed power supplies, and improving the power supply reliability and the safety of the power grid.
