Distribution network line single line diagram abnormity diagnosis and analysis method, system and device

Abstract

The invention relates to the technical field of power distribution networks, and discloses a distribution network line single line diagram abnormity diagnosis analysis method, system and device. According to the line current data of the distribution network line in the single line diagram in the automatic master station system and the corresponding power supply distribution transformer number of the line in the line production ledger data, whether the distribution network line is abnormal or not is evaluated; calculating line loss on two sides of a contact point in an electricity room of the line according to the electric quantity data of the line and the distribution transformer of the metering automation system so as to determine whether the lines on two sides of the contact point are abnormal or not; and calculating the line loss and line loss rate of the distribution network line relative to the line production ledger data, the line marketing ledger data and the line metering ledger data according to the electric quantity data so as to determine the distribution network line with power transfer, and further generating corresponding single line diagram abnormity diagnosis analysis information according to an obtained judgment result. According to the method, the data of each professional system is combined, and efficient and intelligent diagnosis analysis of the distribution network single line diagram abnormity is realized.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a method, system and device for diagnosing and analyzing abnormality of a single-line diagram of a distribution network line. Background technique [0002] In order to realize the safe operation and management of the distribution network, power companies have set up a distribution network dispatching management agency to coordinate and command the distribution network in a unified manner. Tool, its consistency with field equipment will directly affect the coordination and command effect of distribution network scheduling. [0003] At present, the change of the one-line diagram of the distribution network is generally initiated by the operation and maintenance unit of the distribution network, approved at all levels, and finally transferred to the distribution network scheduling node for publication. During the period, the verification of the one-line diagram of the ...
