对输电线路进行防雷改造需要考虑诸多因素。基于可拓层次分析法（extension analytic hierarchy process,EAHP）的基本原理和待改造线路杆塔现状确定待选防雷改造措施,综合考虑雷击跳闸率降低效果、费用、施工、维护、对系统影响五个指标对待选防雷改造措施进行排序。对定性指标采用可拓区间数来量化其相对重要性;对定量指标采用线性插值来量化其相对重要性,以减少人为因素对综合评估结果的影响。在得到各措施占每个指标的权重后,综合每个指标的权重得到防雷改造措施的优先次序。用该方法对某500 kV线路雷击风险高的三基杆塔进行防雷改造,得到了各基杆塔的最佳防雷措施,并且具有良好的防雷效果。...

Many factors need to be considered for lightning protection retrofitting of transmission line. Alternatives of lightning protection retrofitting were acquired by considering the present situation of the towers and extension analytic hierarchy process（ EAHP）. The measures of lightning protection retrofitting are lined up by comprehensively considering five indexes,such as the reduction effect of lightning trip-out rate,retrofitting cost,retrofitting difficulty,maintenance difficulty,the effect to the power system. In order to reduce the impact...
