Abstract

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.

Description

technical field [0001] The invention relates to the field of distribution networks, in particular to a distribution network-to-supply analysis method and system thereof. Background technique [0002] Power supply reliability is an important indicator reflecting the development level of distribution network technology, and planned blackout is a key factor affecting power supply reliability. Due to the many factors affecting planned power outages, the trend calculation method based on historical data has been used to measure the impact of planned power outages on the reliability of power transfer, which has low accuracy and cannot provide effective support for eliminating the impact of planned power outages. Contents of the invention [0003] The purpose of the present invention is to provide a distribution network transfer power supply analysis method and its system. The analyzed results obtained by the method and the system can provide a basis for handling the distribution...
