Power grid topology technology-based loop construction method and a storage medium

Abstract

The invention discloses a loop construction method based on a power grid topology technology and a storage medium. The method comprises the steps of traversing line outgoing points of station rooms ina power grid; acquiring a line corresponding to an outgoing line point and a branch line of the line according to the topological relation between the outgoing line point and the line; acquiring out-of-station connecting lines, out-of-station super connecting lines and cable segments of the lines and the branch lines of the lines according to the topological relation in the PMS graph; according to the out-of-station connecting line, the out-of-station super connecting line and the cable section, obtaining a line outgoing point of a terminal point of the line and a branch line thereof; according to the topological relation between the line outgoing point and the container, obtaining a station house corresponding to the line outgoing point of the terminal point; acquiring in-station equipment of the station building according to the affiliated relationship of the station building; obtaining out-of-station equipment according to the relation between the line and the branch line thereof;and performing topology association on the in-station equipment and the out-station equipment according to the topology relationship between the connection node and the equipment terminal to generatea loop. Human workload can be greatly reduced, loop generation efficiency is high, and accuracy is high.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a circuit construction method and storage medium based on power grid topology technology. Background technique [0002] In the power quality reliability business of the electric power industry, it is necessary to analyze the reliability indicators of the power grid according to the loop. The traditional power transmission and transformation reliability assessment technology of the power grid adopts a manual method, using the affiliation relationship and human experience of the equipment account in the power grid production database Classify and divide the main network lines into loops, and conduct reliability assessment based on the loops. [0003] This analysis technology for loop division of the main network lines from the data end has a huge amount of data, low accuracy, cumbersome work, and long system response time during the analysis process, which cannot meet the accuracy and ...

Problems solved by technology

[0003] This analysis technology for loop division of the main network lines from the data end has a huge amount of data, low accuracy, cumbersome work, and long system response time during the analysis process, which cannot meet the accuracy and practical requirements, and ignores the power grid. Characteristics of the topology, such as switch states, live states, power points, etc.

[0004] Therefore, the existing technology does not use a model that conforms to the characteristics of the power grid structure to manage topology data, resulting in a huge human workload, a long time-consuming server memory loading process, low accuracy of loop generation results, and lack of authenticity in event generation results. The obtained reliability assessment is inaccurate and cannot guide the power transmission and transformation reliability work of the power grid
