摘要： 采用电磁暂态计算软件(ATP-EMTP)仿真分析直流线路与接地极线路同塔共架线路杆塔遭受雷击后的响应。验证改进Mayr电弧模型对研究的适用性,建立具有频率响应的输电线路仿真模型、多波阻抗的杆塔模型、基于先导法的空气间隙击穿模型,分析接地极线路对直流线路反击耐雷水平的影响,以及接地极线路招弧角的放电情况。研究表明:由于接地极线路差绝缘的保护作用,直流线路的反击耐雷水平提高约45.9%;单极大地运行情况下,雷击点处多基杆塔的招弧角间隙建立持续电弧,引发接地极线路多点接地故障。

Abstract: The HVDC line and earth electrode line might be constructed using common tower, but there was lack of research on the back flashover performance of HVDC line, whats more, the earth electrode line arcing horn discharge characteristics was also scanty, in the case of tower struck by lightning. The frequency characteristic simulation transmission line, multi-impedance tower model and air gap breakdown model were established by ATP-EMTP, the influence of electrode line on back flashover level for HVDC line was studied, and the arcing horn discharge characteristics was researched. The results showed that, back flashover performance of HVDC line could obviously be improved by earth electrode line, and lasting arc could be established by DC current in the single pole operation mode.

Key words: ATP-EMTP, arcing horn, common tower, arc current, electrode line
