Power transmission line bird-related fault bird type hazard grade classification method

Abstract

The invention provides a power transmission line bird-related fault bird type hazard grade classification method. According to the method, population ecology, community ecology and protection biologytheories, a focus animal method, an instantaneous scanning method and a sample point method are utilized; the sex, age structure, richness, distribution and diversity of birds around the typical habitat of the power grid, a foraging strategy and a breeding behavior rule are investigated and studied; a bird hazard level model based on indexes such as bird damage faults, bird types, bird flight capabilities and bird life habits of the bird related fault bird species is established; according to the method, scientific and effective hazard grade evaluation is carried out by using the bird hazard grade model, and the difficult problems of discrimination, habit cognition and the like of bird hazard types which troubles power grid operation and maintenance personnel in the aspects of bird-relatedfault hazard types of power transmission lines for a long time are solved through the bird-related fault bird hazard grade classification method. Timeliness, scientificity and effectiveness of bird-related fault early warning and prevention work are improved, and guarantee is provided for safe and stable operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of high-voltage electricity, in particular to a method for classifying hazard levels of bird species due to bird-related faults in power transmission lines. Background technique [0002] In recent years, with the country's emphasis on environmental protection and increased investment in governance, my country's green space coverage has increased significantly. With the continuous extension of the power grid and the improvement of the ecological environment, the activities of birds near overhead transmission lines have increased, resulting in the continuous increase of bird activities. Lightning strike and external force damage become the third major reason for tripping of transmission lines, which seriously affects the safe and stable operation of the line. [0003] The safe and reliable operation of transmission lines is an important guarantee for the security of the power grid and the reliability of power s...

Problems solved by technology

Due to the large number of birds on the transmission line, the hazard levels are also different. However, because most of the current line operation and maintenance personnel are from electric power engineering, and the knowledge of birds is extremely lacking, it is difficult to identify the hazard level of bird-related faults.

Therefore, there is a large blindness in the prevention and control of bird-related faults at present, resulting in the blind installation of a large number of bird-proof devices during the bird-proof renovation process, not only failing to achieve the corresponding bird-proof effect, but also causing a waste of funds
