Problems solved by technology

[0003] The distribution automation system is oriented to distribution network scheduling and distribution network operation and maintenance. The modeling requirements of the two are inconsistent. Distribution network scheduling focuses on the network architecture and protection characteristics of the distribution network, while distribution network operation and maintenance focuses on the power outage range and users of a single line. attributes, resulting in the same graph unable to meet the diverse needs at the same time

Abstract

The invention provides a distribution network line intelligent mapping method, device and system, and the method comprises the steps: receiving middle station single line diagram data, converting the middle station single line diagram data into an automatic graph model file based on a standard conversion rule, and analyzing the automatic graph model file to form a single line source diagram; identifying interconnection switches from the single-line source diagram, and identifying interconnection line types to a transformer substation bus through the interconnection switches to form a single-line sketch diagram or a multi-line looped network diagram; the operation constant value of the power distribution terminal is measured, and the constant value is combined with the single-line sketch to form a power distribution network single-line constant value graph. Based on the method, the invention also provides a distribution network line intelligent mapping device and system, four different graphs, namely a source graph, a sketch, a looped network graph and a fixed value graph, are respectively formed, different graphs are extracted for different users and different scenes, power supply path visualization, protection fixed value visualization and power failure range visualization are realized, and the distribution network line intelligent mapping method has the advantages of being high in practicability and easy to popularize. And the operation and maintenance and accident handling work efficiency of the power distribution network terminal is greatly improved.
