| Abstract: | 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 out- age 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. |
