Embodiment 1

[0038] This embodiment provides a method for judging transmission line overlapping maintenance, see figure 1 Structure shown, including:

[0039] Step S1, constructing an electrical contact relationship according to the maintenance sequence of the transmission lines that have been scheduled for maintenance.

[0040] The so-called electrical contact relationship is a contact relationship constructed by referring to the maintenance schedule of the transmission lines in the current power grid that have been scheduled for maintenance.

[0041] Step S2, use the binary tree traversal algorithm to find out the impact of power outages caused by the maintenance of the target transmission line, use the "binary tree" traversal method to visit each transmission line in the constructed electrical connection diagram and only visit once, while improving the accuracy rate Improved access rate.

[0042] Step S3, judging whether the simultaneous maintenance of the target transmission line and...

Embodiment 2

[0059] This embodiment provides a transmission line overlapping maintenance judgment system, including:

[0060] The construction unit is used to construct the electrical contact relationship according to the maintenance sequence of the transmission lines in the current power grid;

[0061] a first search unit, configured to search for a target power transmission line;

[0062] The judging unit is used to judge whether the simultaneous maintenance of the target transmission line and the transmission line that has been scheduled for maintenance will result in only one effective power input line for important substations or primary customers.

[0063] Preferably, the building unit also includes:

[0064] an acquisition unit, configured to acquire the maintenance sequence of the transmission line;

[0065] The modeling unit is used to construct the electrical connection relationship according to the maintenance sequence of the transmission line.

[0066] Preferably, the transm...

Abstract

The invention relates to the field of electric power equipment, and particularly relates to a power transmission line overlapping maintenance judgment method and system. Electrical connection formed by a target power transmission line and a power transmission line under maintenance is searched by using a "binary tree" traversal algorithm and displayed so that work personnel are enabled to rapidly identify the power outage influence caused by maintenance of the target power transmission line. Meanwhile, whether overlapping maintenance is formed between the target power transmission line and the power transmission line under maintenance is judged, and maintenance arrangement is timely adjusted before performing maintenance of the target power transmission line so that the phenomenon of large-area power outage of important transformer substations or first-class customers caused by overlapping maintenance of the power transmission line can be effectively avoided.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a method and system for judging transmission line overlapping maintenance. Background technique [0002] Timely inspection and maintenance of transmission lines is one of the effective ways to avoid transmission line failures. As we all know, important substations (such as substations where shopping malls, playgrounds, etc.) and primary customers generally use two transmission lines to ensure power supply. reliability. If a power transmission line has been arranged for maintenance, and then a certain target transmission line is arranged for power outage maintenance, it may result in only one effective power input line remaining for public substations or important customers, which constitutes a phenomenon of overlapping maintenance, and due to the instability of objective factors, when When only one remaining power input line loses power due to a fault, it will cause a power outage...
