The invention provides a power supply transfer check
analysis method and
system for a power distribution network. The method comprises the steps of S1, acquiring network framework structure information of the power distribution network, and dividing a power distribution
network structure according to a preset power distribution
network structure layering principle, specifically, dividing the network framework structure of the power distribution network into a
trunk layer, a
branch layer and a user layer, wherein the
trunk layer comprises a 10kV overhead or
cable line part which is fed out froma
transformer substation or a switching
station and undertakes a main
electric energy transmission and
distribution function, and a line section part with a contact function; the
branch layer comprises a 10kV line part which is led out from a 10kV
trunk line, except the trunk layer; the user layer comprises a distribution transform part for directly supplying power to a user; and S2, conducting power supply transfer check analysis on the trunk layer, the
branch layer and the user layer obtained by division in the step S1. The
system is used for realizing the method. A check analysis result can be used as a basis of a
processing mode for eliminating the influence of scheduled outage.
