Lightning protection configuration method for newly-built power distribution network

Abstract

The invention discloses a lightning protection configuration method for a newly-built power distribution network. The lightning protection configuration method comprises the following steps: determining a lightning area grade of an area where each power distribution line in the newly-built power distribution network is located and an importance degree grade of power distribution network equipment; determining the lightning protection grade of the distribution line according to the lightning area grade of the area where the distribution line is located and the importance degree grade of power distribution network equipment; and configuring a corresponding lightning protection measure for each distribution line of the newly-built distribution network according to the lightning protection level of the distribution line. According to the embodiment of the invention, the effectiveness and pertinence of lightning protection measures of the newly-built power distribution network can be effectively improved, and the efficiency and economic benefits of lightning protection work are improved.

Description

technical field [0001] The invention relates to the technical field of electric power system lightning protection, in particular to a lightning protection configuration method for a newly-built distribution network. Background technique [0002] With the development of my country's economy towards high-quality goals, the people's demand for power supply reliability is getting higher and higher. Due to its own attributes: low insulation level, wide distribution and complexity, distribution lines are prone to lightning tripping faults. In addition, distribution lines may be tens of kilometers long, and the environmental conditions of each line section are different, such as the height and density of trees and buildings, resulting in different lightning strike risks. [0003] After the newly built distribution network system, lightning protection configuration will be carried out accordingly. Although the lightning strike failure rate of the distribution network system is ver...

AI Technical Summary

Problems solved by technology

The current lightning protection measures do not treat the entire line differently, resulting in waste of resources and large economic investment in places where lightning protection measures are not required; in some distribution lines and road sections with high lightning strike rates, often The effect of lightning protection is not obvious due to insufficient investment in lightning protection measures
