Protection method and system of power transmission tower

Abstract

The invention, which relates to the technical field of the power transmission equipment, provides a protection method and a system of a power transmission tower. The protection system of the power transmission tower comprises: a wireless sensor network, which is laid on the tower body and around the tower body of the power transmission tower as well as is used for detecting a signal that indicates the power transmission tower is threatened and converts the signal to data; a convergent node, which is used for connecting the wireless sensor network, obtaining data from the wireless sensor network, carrying out buffer memory and processing on obtained data and transmitting processed data through a mobile communication network; and a monitoring platform, which is used for obtaining data that is transmitted by the convergent node through the mobile communication network. According to another aspect of the invention, a cooperative and perceptive network is formed by a plurality of sensors, so that a target identification capability, a multi-point fusion capability and a cooperative and perceptive capability are realized; in addition, effective classification, area location and early warning of wrongful behaviors to the high-voltage and mainstay power transmission tower can be realized, and the overall protection of the high-voltage and mainstay power transmission tower can be realized.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a protection method and system for power transmission towers. Background technique [0002] With the rapid development of the national economy, the operation of the national economy relies more and more on the supply of electric energy. The safe operation of high-voltage and ultra-high-voltage backbone transmission networks is directly related to the safe operation of the entire power grid, and it is also related to national economic security and social stability. The external threats to the safe operation of the power grid mainly come from three aspects: natural disasters, external savage construction, and man-made sabotage. [0003] In recent years, with global warming, severe weather such as typhoons, heavy rains, and severe thunderstorms have occurred frequently, resulting in frequent natural disasters such as flash floods, destroyed foundations of tower...

Problems solved by technology

Line inspectors regularly inspect high-voltage lines. This work is extremely difficult. The labor intensity of the line inspectors, the sense of responsibility of the line guards and the uneven knowledge of line guards, the hardship of field work and the difficulty of reaching some line towers , it will make it difficult to guarantee the effect of line inspection work, and the long line inspection cycle (1 to 10 weeks) will lead to the absence of line status supervision, which will leave hidden dangers to the safety of transmission lines
