| 摘 要： | 冀北大同超高压供电公司所辖500kV 源安二线是2003年4月投产的,由于沿线经过山区,每年发生1~3次雷击跳闸事故.针对此问题,采用蒙特卡罗法对该线路的防雷性能进行计算分析,并于2006年提出综合治理措施,包括接地网改造、安装防绕击避雷侧针、安装线路避雷器等.计算结果以及2007—2009年的运行结果证明了500kV 源安二线防雷综合治理措施的有效性以及蒙特卡罗法的有效性

| Abstract: | The 500kV Yuan-an No.2 transmission line,which belongs to Jibei Datong EHV Power Supply Corporation and was put into operation in April,2003,passes through mountain area,so every year there are one to three times of lightning trip-outs occurred in the transmission line.To solve this problem,the lightning protection performance of this line is calculated and analyzed by Monte Carlo method,and comprehensive improvement measures for this line was proposed in 2006,including grounding grid renovation,installing sideward rods against shielding failure,installing line arresters and so on.The effectiveness of the proposed comprehensive improvement measures and the availability of Monte Carlo method are verified by actual running results of the improvement measures from 2007 to 2009. |
