论文摘要
这项工作提出了一种估计传输线和变电站恢复时间的方法，并在20个飓风场景下的波多黎各的现实世界中的1269-BUS电力系统模型中进行了证明，或在飓风Maria的气象条件下对资产失败的随机实现。该方法定义了系统组件的基本恢复时间，并通过乘数来确定影响这些基本值的因素。虽然该方法在传输线和由于飓风导致的变电站故障上进行了测试，但它基于一个通用过程，该过程可以作为一般恢复时间估计框架应用于任何系统组件或事件。结果表明，鉴于正在研究的两种故障模式（变速箱塔和变电站），尽管变电站给出了更长的基本停电时间，但传输塔似乎对恢复时间的估计产生了更大的影响。此外，在20个场景中，模拟飓风的平均恢复时间约为28,000名工作人员日。
This work proposes a methodology for estimating recovery times for transmission lines and substations, and is demonstrated on a real-world 1269-bus power system model of Puerto Rico under 20 hurricane scenarios, or stochastic realizations of asset failure under the meteorological conditions of Hurricane Maria. The method defines base recovery times for system components and identifies factors that impact these base values by means of multipliers. While the method is tested on transmission lines and substation failures due to hurricanes, it is based on a generic process that could be applied to any system component or event as a general recovery time estimation framework. The results show that given the two failure modes under study (transmission towers and substations), transmission towers appear to have a greater impact on recovery time estimates despite substations being given longer base outage times. Additionally, average recovery times for the simulated hurricanes across 20 scenarios is ~28,000 work crew days.
