Online monitoring and early warning system for galloping of power transmission line

Abstract

The embodiment of the invention provides an online monitoring and early warning system for the galloping of a power transmission line, and the system comprises a galloping monitoring device, a micro-meteorological monitoring device, a camera device, a monitoring base station, and monitoring center equipment. The monitoring base station transmits the meteorological information collected by the micro-meteorological monitoring device, the motion data collected by the galloping monitoring device and the image information collected by the camera device to the monitoring center equipment. The monitoring center equipment judges whether an environment can cause the galloping of the power transmission line or not according to the meteorological information, and calculates the motion track of the power transmission line according to the motion data. When the environment can cause the galloping of the power transmission line, the early warning operation is started, and the galloping degree of thepower transmission line is determined through the comparison of the motion track and the image information. The system can achieve the automatic judgment of whether a meteorological environment can cause the galloping of the power transmission line or not, can achieve the early warning timely, and determines the galloping condition through the comparison of the motion track and the image information. The monitoring result is more reliable.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of online monitoring of power transmission lines, and more specifically, embodiments of the present invention relate to an online monitoring and early warning system for galloping of power transmission lines. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, my country is building a strong smart grid characterized by informatization, automation, and interaction, based on the UHV grid as the backbone grid and the coordinated development of grids at all levels. Its characteristics are that it can realize large-scale, long-distance power transmission, low power grid loss, free interconnection, and can flexibly adapt to the operation requirements of the power market. However,...

Problems solved by technology

[0004] With the rapid economic growth in recent years, the contradiction between line corridors and local construction land has become increasingly prominent. As a form of overhead transmission lines, compact lines can effectively compress line corridors and save engineering land, but compact lines and conventional lines There are obvious differences in tower structure, wire hanging method, phase distance, etc. Under the same weather, ice and landform conditions, compact lines are more prone to galloping than ordinary lines, and tripping faults are more likely to occur after galloping occurs. Therefore, It is necessary to implement 24-hour real-time monitoring on compact transmission lines, so as to realize early warning before galloping occurs, and ensure the safe and stable operation of transmission lines

[0005] In the traditional mode, the monitoring of the galloping phenomenon of transmission lines can only rely on manual inspection, which has low work efficiency, wastes a lot of manpower and material resources, and cannot realize 24-hour real-time monitoring
