Embodiment Construction

[0026] Below in conjunction with example and accompanying drawing, the present invention is described in further detail.

[0027] The invention is a method for assessing the risk level of bird droppings faults in a power grid, such as figure 1 As shown, this method can be realized by writing program code. Include the following steps:

[0028] (1) Collect relevant information;

[0029] (2) Establish a data matrix;

[0030] (3) Data standardization;

[0031] (4) Establish fuzzy similarity matrix;

[0032] (5) cluster analysis;

[0033] (6) Divide risks, etc.

[0034] 1. Collect relevant information:

[0035] Relevant data refers to the data related to the risk level of bird damage caused by bird droppings faults on transmission lines in the research area.

[0036] The collection of relevant data includes: geographic data, bird data, and bird-related fault-related data.

[0037] 1.1 Geographic data:

[0038] Geographic data include the distribution of rivers, lakes, res...

Abstract

The invention relates to the technical field of transmission lines of power grids, especially relates to a method for assessing guano class failure risk levels of a power grid, and specifically relates to a method for assessing the guano class failure risk levels of the power grid based on fuzzy cluster analysis. The method comprises the following steps: collecting relevant data; establishing a data matrix; performing data standardization; establishing a fuzzy similarity matrix; performing cluster analysis; and dividing risks. According to the method for assessing the guano class failure risk levels of the power grid provided by the invention, the clustering result is more reasonable, which can provide reliable data for relevant personnel; and the method is beneficial to the practical application of dividing the guano class failure risk levels, and provide a practical guiding significance for the development of the design and operation and maintenance of the transmission lines. And besides, the method is higher in accuracy and convenient in use, which can not only take into account the security of a power system, but also can effectively maintain the power grid trip fault rate caused by birds, thereby effectively guaranteeing the safe and stable operation of the power system, and reducing unnecessary economic loss due to the birds.

Description

technical field [0001] The present invention relates to the technical field of power grid transmission lines, in particular to a method for evaluating the risk level of bird droppings faults in a power grid, in particular to a method for evaluating the risk level of bird droppings faults in a power grid based on fuzzy cluster analysis. Background technique [0002] In recent years, the country has paid more and more attention to environmental protection and improved relevant laws and regulations. The living environment of birds has become better and better, the population and number of birds have also increased, and their range of activities has also expanded. However, because people's awareness of environmental protection was poor in the past, a large amount of vegetation was destroyed, trees were cut down, and the nesting space for birds was greatly reduced. The frequency of activities is high, and there are more and more grid tripping faults caused by bird damage, which h...
