摘要
电网是保障现代社会正常运转不可或缺的关键基础设施,我们日常生活所需的许多基本服务都依赖于电网所提供的电力。中国是一个地震多发国家,世界上较为严重的地震有33%都发生在这个仅占全球陆地面积7%的国家。地震能对电网造成广泛破坏,而停电又将影响依赖于电力的基础服务,进一步恶化地震后果。因此,电网在地震灾害下的性能研究受到了学术界以及工业界的普遍重视,大量的研究成果层出不穷。基于地震灾害下电网性能研究的一般框架,对现有文献从如下四个方面进行了综述:地震灾害情形模拟、电网元件脆弱性建模、电网功能变化过程仿真、电网抗震性能评估与改进。需要注意的是,电网性能可以从脆弱性、可靠性、风险等多个视角进行评估,这里着重从弹性视角进行了研究现状分析。最后总结了当前研究中存在的问题以及未来研究的热点方向。
