摘要:
输电线路抗震韧性研究有助于确定震后输电线路功能损失和恢复时间,为震后电力系统恢复提供重要参考。基于2008年汶川8.0级地震后成都、绵阳、德阳、广元和阿坝5个地区的输电线路震害资料,分析了输电线路功能失效、恢复情况,建立了功能失效、恢复时间与破坏情况的对应关系函数,结合韧性定义给出输电线路功能损失累积函数,划分了韧性水平等级,形成了以电压等级、长度、地形地貌为参数的输电线路抗震韧性计算方法。使用该方法对我国某地区输电线路进行试算,计算结果与以往对输电线路震害情况的定性判断基本相符,能够揭示出该地区输电线路在低烈度时损失较轻、在高烈度时损失较重的基本规律。
Abstract:
Seismic resilience study helps to assess the functional loss and the recovery time of the transmission lines.It also provides a reference for post-earthquake recovery of the power system.Based on the data of the seismic damage to the transmission lines in regions like Chengdu,Mianyang,Deyang,Guangyuan and Aba after the Wenchuan MS8.0 earthquake in 2008,the functional failure and recovery of the transmission lines are studied.The correlation function between the functional failure and the damage to the transmission lines is built.The correlation function between the recovery time and the damage to the transmission lines is built too.On the basis of the definition of the resilience,the functional cumulative loss function of the transmission lines was established.Then the seismic resilience ranks are put forward.A method to calculating the seismic resilience of the transmission lines is developed,which involves voltage and length of the transmission lines,and topography of the areas which the transmission lines go through.The method proposed in this paper is applied to the calculation of the seismic resilience of the transmission lines in an earthquake-stricken area,and the results are generally consistent with the post-earthquake,field investigation of the seismic damage to the transmission lines.This proves that in mountainous areas the transmission lines would suffer less losses when hit by low intensity ground motion,and would suffer more losses when hit by high intensity ground motion.
