摘要(Abstract):
雷击导致同塔双回线路同时跳闸,会对电力系统稳定运行造成较大的冲击。结合220 kV商瞬2Q98线、商岙2Q99线同塔双回线路同时雷击跳闸停运的情况,根据雷电定位系统的雷击跳闸查询结果和有关计算结果,分析了该同塔双回线路同时雷击跳闸的原因,提出了防止220 kV同塔双回输电线路同时雷击跳闸的综合防雷措施。
Simultaneous tripping and outage of double-circuit transmission lines on the same tower due to lightning strike can greatly impact the stable operation of power system.In combination with tripping and outage of double-circuit transmission lines on the same tower in 220 kV Shangshun 2Q98 line and Shang'ao 2Q99 line,the paper,according to inquiry result of tripping due to lightning strike from lightning location system and the relevant calculation,analyzes reasons of simultaneous tripping and outage of the double-circuit transmission lines on the same towers and proposes comprehensive lightning protection measures to prevent tripping due to lightning strike on 220 kV double-circuit transmission lines on the same tower.
