Technical Field

[0001] The present invention relates to the technical field of power transmission line analysis, and in particular to a method for perceiving and analyzing real-scene twin potential of power grid transmission lines. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission; the safety of transmission lines is of vital importance, so it is necessary to monitor the safety of transmission lines.

[0003] In the existing technology, the transmission lines cannot be monitored well and safety predictions cannot be made effectively, which can easily lead to immeasurable losses. Therefore, we propose a real-life twin potential perception and analysis method for power grid transmission lines to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that the transmission lines cannot be well monitored, safety predictions cannot be effectively made, and immeasurable losses may easily occur, and a real-life twin potential perception and analysis method for power grid transmission lines is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] S5. When data A is greater than the transmission line bearing value in the basic database, an early warning is issued;

[0012] S6. Through data comparison, the operation trend of the transmission lines is predicted to realize the situation awareness analysis of the power grid transmission lines.
