摘要
为了避免雷击给变电站运行造成的影响,采用仿真软件对雷击影响下变电站过电压情况进行仿真,并根据仿真结果确定了避雷器配置方案,具体为在500 kV入口位置、距主变电站侧距离25 m以内分别布置一组避雷器。实践表明,该方案可有效避免雷击过电压给变电站运行带来的影响,且所提避雷器配置方案经济、可靠。
In order to avoid the influence of lightning strike on substation operation, the simulation software is used to simulate the overvoltage of substation under the influence of lightning strike, and the lightning arrester configuration scheme is determined according to the simulation solution. A set of lightning arresters within 25 m of 500 kV entrance position and side distance from main substation can effectively avoid the impact of lightning overvoltage on substation operation. The practice shows that the proposed lightning arrester configuration scheme is economical and reliable.
