Reliability Analysis of Electric Power Transmission During the Loma Prieta Earthquake

这是一个事后调查项目，目的是从洛马普里埃塔地震(10月)中吸取工程经验教训。本项目的目的是分析和评价1989年10月17日洛马普里埃塔地震对地震灾区电力传输系统的影响。这些研究旨在为确定主要输电设备的地震易损性函数提供更多信息，这些函数对于大都市地区供电系统的全面可靠性分析是必要和必要的。这项研究还将根据地震造成特定服务区电力中断的可能性来评估主要输电系统的性能。研究计划的结果将作为洛马普列塔地震综合报告的一部分。该项目将有助于确定电力传输设备和装置的地震易损性函数，并有助于开发此类系统的理论模型。

This is a post-event investigation project to learn engineering lessons from the Loma Prieta earthquake (October 1989). The objective of this project is to analyze and evaluate the effects of the Loma Prieta earthquake of 17 October 1989 on the electric power transmission systems in the earthquake- affected areas. The studies are intended to develop additional information for defining seismic fragility functions of major transmission equipment, which are necessary and essential for a comprehensive reliability analysis of electric power supply systems for metropolitan areas. The study will also evaluate the perfomance of the main transmission systems, in terms of the probability of power disruption at specified service areas caused by the earthquake. The results of the study program will be prepared to constitute part of a comprehensive report on the Loma Prieta earthquake. The project will contribute to the definition of the seismic fragility functions of electric transmission equipment and devices and to the development of theoretical models for such systems.
