35kV风电场架空集电线路不同防雷方式等同性研究
Study on Equivalence of Different Lightning Protection Methods for Overhead Power Collection Lines in 35 kV Wind Farm
摘要
Abstract
The overhead collector lines of 35 kV wind farm are mostly located in the mountain rock area with light-ning and tripping rate and,therefore corresponding lightning protection measures are necessary.At present,it is dif-ficult to reduce the grounding resistance in the mountain rock area,the cost is high and the grounding resistance val-ue is difficult to meet the standard.In this paper the equivalent resistance reduction and lightning protection mea-sures of overhead collector lines in 35 kV wind farm are studied.The results show that when the coupling ground wire is installed,the lightning resistance level can reach the level when the grounding resistance is 5 Ω.When the line ar-rester is installed on the 35 kV collector line,the increase in lightning resistance levels for lightning shield line GJ-100,OPGW,and conductors are 8.23 times,7.86 times,and 70.8 times respectively.They,compared to reducing ground resistance,show a more significant improvement effect.This research will provide guidance on lightning protection methods to achieve the same lightning resistance level for the 35 kV wind farm's collector lines,where the existing grounding resistance of the lines is difficult to be reduced.关键词
