Transmission Line Fault Location and Display System

Abstract

The invention discloses a transmission line fault location module, which belongs to the technical field of transmission lines. The transmission line fault location module comprises a data maintenance module, a fault location module, and an operation abstraction module. The operation abstraction module maps transmission line data imported by the data maintenance module to an electronic map to form an electronic map at least including high-speed rails, highways and important transmission channels. The fault location module calculates out the line length from a transmission line fault point to a substation based on transmission line recording data. The operation abstraction module displays the location of the fault point and the environment around the fault point on the electronic map containing the transmission line data according to the calculation result of the fault location module to help a dispatcher to learn about the environment around the fault point quickly and issue a dispatch instruction in time.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, and in particular relates to a system capable of displaying fault locations of power transmission lines. Background technique [0002] The power industry is the economic lifeline of the country, and the safety and stability of the power system are closely related to national construction and public interests. my country's 110 kV and above voltage transmission lines are all erected in the air. There will inevitably be high-speed railways, highways, or other important transmission lines on the ground below the transmission lines. The transmission lines span high-speed railways, expressways, and other transmission lines. The situation of the line is generally called "three-span" line in the industry. When a "three-span" line fails, if the fault point is in the crossing area, not only the faulty line cannot operate normally, but the faulty line will also cause the outage of high-spee...

AI Technical Summary

Problems solved by technology

[0004] First, it is difficult to accurately and quickly locate the fault point of the line

After the "three-span" line fails, the controller can only comprehensively measure the fault location and the distribution of the cross-span section in the "three-span" line detailed ledger, and roughly estimate whether the fault location is located in the "three-span" section. duration

[0005] Second, it is difficult to intuitively and comprehensively grasp the direction of the line path

At present, the primary wiring diagram and geographic wiring diagram used by controllers can only simply display the connection relationship at each end of the line, and do not display the number of towers, geographical location, and path direction of the line, which directly causes the controller to not grasp the actual spatial layout of the line. It is impossible to accurately define the area of ​​the line route, and it is impossible to quickly and accurately notify the personnel in the area where the faulty transmission line belongs to start the emergency plan and live line inspection

[0006] Third, it is difficult to know the environmental conditions of the line in real time and accurately

During the operation of the line, it will be affected by many objective factors such as weather, road conditions, trees, buildings, etc., and the existing control technical support system cannot obtain the operating conditions of the line in real time, which leads the controller to determine whether the line is faulty. Insufficient valid information to base the condition on

[0007] Fourth, it is difficult to grasp the emergency response dynamics of the operation and maintenance department in real time

After the accident, the control personnel cannot intuitively grasp the dynamic situation of the relevant operation and maintenance management personnel rushing to the substation and the fault point, and cannot grasp the emergency response situation of each department in real time, and relevant supervision, command, and assessment work cannot be carried out
