摘要
750 kV输电线路是西北地区骨干网架的重要组成部分,确保其安全运行对电网的稳定具有重要作用。根据雷电定位系统监测信息,结合线路所处高海拔地区的特点,对750 kV拉宁线跳闸故障进行了深入分析,并提出了有针对性的防雷整治措施,可为高海拔地区750 kV输电线路的设计、运行和维护提供参考。
As a backbone of the Northwest grid, 750 kV transmission lines play a decisive role to ensure the grid operating safety and stability. The paper illustrates the tripping information monitored by the lightning location system and the operating characteristics of 750 kV transmission line in the high altitude areas. The comprehensive analysis is conducted for the tripping. And suitable measures against the tripping of 750 kV transmission line are put forward. It can be used as referenee for those who will carry out design, operation and maintenance of 750 kV transmission line in high-altitude areas.
