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。Electric power grids play an important role in the smooth functioning of modern society as many essential services required in our daily life depend on the electricity. Many cities in China are located in the earthquake- prone regions. If an earthquake occurs, it may cause extensive damage to power facilities and lead to a blackout, which will further affect electricity-depended critical services and result in huge economic loss. The seismic per- formance studies on electric power grids in the literature have been extensively reviewed from four aspects： seismic scenario generation, component fragility modeling, system-level functionality simulation, and seismic performance assessment and enhancement. Note that the performance of electric power grids can be measured from different perspectives, such as vulnerability, reliability and risk, this review has been mainly conducted from the resilience perspective. Finally, existing problems in the literature have been concluded and several directions for future work have been also provided.
