Distribution network breakpoint diagnosis method based on electrical topology and related device

Abstract

The invention discloses a distribution network breakpoint diagnosis method based on electrical topology and a related device, and the method comprises the steps: judging whether a graphic model file imported into a distribution network master station is normal, if yes, obtaining the current listing state of each feeder line in the graphic model file, and when the listing state is a non-maintenance state, determining the equipment type of the interruption point according to the equipment information in the graph model file; and when the break point is an acquisition switch, judging whether parameters associated with the break point are correct or not according to the data type of an associated point of the break point, if so, obtaining the on-off state of the break point, and when the on-off state is a closed state, obtaining a connection relation list according to the equipment information of the break point, and comparing the connection relation list with a connection relation list in a preset database to determine whether the interruption point lacks the connection relation, thereby solving the problems that the existing graphic model quality verification method does not detect the graphic model imported into the master station, the problem can be found only when the application operation is abnormal, and the operation safety of the power grid is influenced.

Description

technical field [0001] The present application relates to the technical field of distribution network, in particular to a method for diagnosing interruption points of distribution network based on electrical topology and related devices. Background technique [0002] With the development of distribution network technology, the intelligent application of distribution network master station is increasingly dependent on the distribution network diagram. The quality of the distribution network diagram has a great influence on the practical level of advanced applications such as power traceability and fault location. In the distribution network one-line diagram GIS platform, various distribution network equipment graphics elements and drawing methods have been unified and standardized. However, due to the differences in the level of the one-line diagram drawing personnel, the quality of the one-line diagram model is also uneven. Affected by the basic data entry of the distributi...

Problems solved by technology

[0004] This application provides a method for diagnosing distribution network interruption points based on electrical topology and related devices, which are used to improve the existing image quality verification method. It does not detect the image after it is imported into the master station, and it can only appear when the application is running. Problems can only be found when there are abnormalities, and technical problems that affect the safety of power grid operation
