Incremental distribution method from single line diagram to geographical wiring diagram of power distribution network

Abstract

The invention discloses an incremental distribution method from a single line diagram to a geographical wiring diagram of a power distribution network. Comprising the following steps: taking a feeder line of which equipment is changed as a basic edge cloth unit; firstly acquiring editing state and running state single line diagrams of a to-be-distributed feeder line from a power grid production management system; according to the editing state and operation state single line diagrams, obtaining incremental change data of the current editing state through comparative analysis from the single line diagram equipment graph and equipment ledger level; generating and maintaining equipment topology information according to the analyzed incremental change data; and finally, according to the topological information of the equipment, calculating the geographic coordinates of all other equipment of which the geographic coordinates are not maintained in the single line diagram, completing incremental distribution of the single line diagram, and automatically distributing incremental distribution data into a geographic wiring diagram data model. According to the invention, the increment distribution of the edit-state single line diagram is efficiently completed with extremely low analysis cost and data transmission quantity.

Description

technical field [0001] The invention relates to an incremental distribution method from a distribution network single-line diagram to a geographic wiring diagram, and belongs to the technical field of power grid equipment management. Background technique [0002] Geographic wiring diagram of distribution network is a basic graphic commonly used in distribution network operation and maintenance management. It has a wide range of application scenarios in power outage information visualization, industry expansion report and installation plan assistance formulation, fault repair, and power asset life cycle management. [0003] At present, the geographic wiring diagrams in the production management system of the State Grid Corporation of China are mainly drawn manually, and the efficiency is relatively low. In recent years, relevant researchers have begun to study the automatic generation technology of geographic wiring diagrams in depth, that is, while maintaining the one-line d...

Problems solved by technology

Its shortcoming is to carry out the full analysis of the one-line diagram. When writing the data along the layout into the equipment model table of the geographic wiring diagram, it is necessary to delete the relevant stock data in the model table of the geographic wiring diagram first, and then insert the equipment data generated by the full analysis of the one-line diagram. The layout efficiency is low. In addition, if the one-line diagram changes less equipment, this shortcoming of full-scale layout will be more obvious.
