Problems solved by technology

[0003] However, in actual engineering, many areas still adopt extensive lightning protection transformation management methods, regardless of the characteristics of transmission lines and lightning protection measures, and choose a single lightning protection measure for treatment without any difference, making the treatment effect insignificant. The tower needs to be rebuilt, which greatly wastes manpower and material resources
The evaluation model of lightning protection measures has shortcomings such as too much influence of human subjectivity, and the factors considered are not comprehensive enough, so it cannot objectively and reliably evaluate the application effect of lightning protection measures

Embodiment Construction

[0051] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0052] see figure 1 , a method for selecting lightning protection measures for transmission lines based on gray relational analysis, including the following steps:

[0053] S1: Obtain the corresponding data information of transmission lines and towers in the corresponding area, and calculate the lightning tripping rate X of each base tower of the transmission line in the area;

[0054] S2: Determine the control index P of the lightning trip rate X of the transmission line in the corresponding area, divide the risk level of the transmission line according to the relationship between the lightning trip rate X of the transmission line and the control index P, and determine the need for lightning protection according to the risk level Retrofitted base tower;

Abstract

The invention provides a method for selecting lightning protection measures of transmission lines based on a grey correlation analysis method, based on the specific situation of each base tower, the grey relational analysis method can be used to optimize the lightning protection measures of transmission line tower, which can reliably obtain the optimal lightning protection measures of transmissionline, and objectively and reliably evaluate the application effect of lightning protection measures.

Description

technical field [0001] The invention relates to the technical field of lightning protection for transmission lines, in particular to a method for selecting lightning protection measures for transmission lines based on a gray correlation analysis method. Background technique [0002] In recent years, power grid operation failures caused by lightning strikes have occurred frequently, and power outages caused by lightning strikes on overhead transmission lines are the main accident types of transmission lines in my country. Many transmission lines inevitably pass through areas with heavy thunder, high soil resistivity, and complex terrain. In order to reduce the lightning tripping of transmission lines in these areas, various lightning protection measures must be taken to improve the lightning resistance level of transmission lines. With the shortage of line corridors, the number of double-circuit or multi-circuit transmission lines on the same tower is increasing, and the heig...
