摘要
为了快速评估变电站震害对辖区电力用户造成的连锁危害情况,确定震时抢险救援的紧急和重点目标,采用归纳总结、统计分析的方法,分析了连锁危害的特征及其影响因素,结合震害经验、震害实例和电力专家经验,基于地震应急基础数据库探索性地建立了变电站震害、用电负荷和电压等级作为危害因子的危害程度快速评估框架。利用2008年汶川地震的破坏资料,对连锁危害评估方法进行了测试。通过对变电站连锁危害评估,可为应急救援决策提供参考。
In order to fast assess the chain hazard caused by substation earthquake damage for the area of power us- ers to determine the post-earthquake emergency and key rescue objectives , by inductive and statistical analysis, the chain hazard characteristics and factors was analyzed. Combined with the earthquake examples and experience, and power expert experience, based on the earthquake emergence basic database, a exploratory rapid assessment framework was proposed, which considered the damage, the electricity load and the substation voltage grade as the hazard factors. Using the damage data of the 2008 Wenchuan earthquake the method was tested. The method is ex- pected to be used to rapid assess the power system earthquake damage and to provide reference to emergency rescue decision-making.
