同塔4回輸電線路差異化防雷效果仿真分析
[Abstract]:The lightning protection effect evaluation of various lightning protection measures is of guiding significance for the lightning protection work of the same tower line. For this reason, EMTP-ATP software is used to reduce the grounding resistance by adopting differential insulation, adding line arrester, adding arc angle to the typical 220 kV,220/500 kV same tower 4 circuit line. The lightning protection effects of 8 kinds of lightning protection measures, such as strengthening line insulation, are simulated and analyzed. The results show that the lightning protection effect of various lightning protection measures is different, and each has technical and economic limitations, which may have an impact on line operation and maintenance, project investment, line imbalance, and lightning resistance level of single circuit line. Therefore, it is suggested to distinguish between newly built and operational lines to carry out lightning protection design and transformation, to emphasize the importance of reducing resistance and strengthening the role of basic lightning protection measures such as insulation, and to point out that the lightning protection measures should not only consider the lightning protection effect, Also consider its economy and the impact on operation and maintenance.
