Embodiment Construction

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] see figure 1 , figure 1 This is a schematic diagram of a complex power line in the embodiment of the present invention. The complex power line in this embodiment is a criss-crossed transmission line composed of various line types such as busbars, trunk lines, and branch lines. Refer to figure 1 The complex power lines in the power line include bus bar 1, bus bar 2, main line 1, branch line 1, branch line 2 and branch line 3. A...

Abstract

The embodiment of the invention discloses a complex power line fault positioning method and system, equipment and a storage medium, a plurality of traveling wave head monitoring sensors are arranged on a complex power line, a plurality of monitoring points on the complex power line can be obtained, the complex power line is coordinated by combining the arrival time and the position corresponding to the monitoring points, and the positioning accuracy of the complex power line is improved. Therefore, a trunk line fault positioning equation related to the line position, the arrival time and the traveling wave propagation speed is established, a first fault point can be simply and rapidly solved, and when the first fault point is located on a branch line, a branch line fault positioning equation is established to obtain a second fault point. The target fault point of the complex power line is obtained based on the first fault point and the second fault point, theoretically, no positioning dead zone exists during fault positioning, a fault section does not need to be determined firstly, the positioning principle is simple, and the positioning accuracy is high. The defect that double-end traveling wave positioning needs to judge a fault section firstly and the traveling wave velocity adopts a fixed light velocity to influence the positioning precision is overcome.

Description

technical field [0001] The present invention relates to the technical field of fault location of AC / DC transmission and distribution lines of power systems, and in particular to a method and system, equipment and storage medium for fault location of complex power lines. Background technique [0002] In the power system, AC and DC transmission and distribution lines are an important part. Line faults will affect the stability of the system and cause power supply interruptions to users. It is time-consuming and laborious to manually find fault points. Fast and accurate line fault location technology is conducive to the timely detection of faulty lines. Repair, reduce economic losses caused by power outages, and ease the hardships of manual patrolling. There are two main types of power system fault location technology: impedance method and traveling wave method. The impedance method is easily affected by factors such as fault resistance, transformer error and power supply param...
