Proposal: CMS-0099638PI: Dorothy ReedInstitution: University of WashingtonDate: May 22, 2001ABSTRACT CMS0099638 "Performance of Electric Utility Lifelines in Urban Centers for Earthquake Hazards" PI: Dorothy Reed, University of Washington. The utility infrastructure system in the US is undergoing significant changes due to deregulation. Recently, structural component failures induced by natural hazards previously considered minor have caused widespread blackouts. The effects of shortages due to natural and man-made causes has been particularly critical for the Pacific Northwest, as compliance with environmental standards places constraints on the generation of power. It has become clear that the US lacks a cohesive approach to electric utility infrastructure reliability. Such a framework would be valuable in identifying the importance of system components and ultimately provide guidelines for improved performance. We propose to develop a reliability-based framework for the performance assessment of power delivery by an electric utility distribution system for earthquake hazards. The distribution system is defined to include components such as the distribution lines, poles, pole-based equipment and substations. Our framework will be focused on the performance of the structural system used to deliver power and its interactions with other critical lifelines. Our approach will significantly expand the three-pronged model developed by Nojima of Gifu University in Japan in which component, system and societal performance measures are blended into a single standard. The valuable lessons learned through the Hyogoken-Nanbu (Kobe) and Nisqually earthquakes will also be incorporated into our investigation. This investigation will require the formulation of proposed performance levels in the context of the present US socio-economic, regulatory and political climate. A major contribution of our project will be to explicitly include, and ultimately clarify, the role of the non-technical constraints of regulations, and in so doing, implicitly evaluate the conditional influence of the political climate upon the development of levels of performance for a US location. Although we will focus on a specific locale within the US [the Pacific Northwest], the adaptation of our approach to other locations in the US should be straightforward.

提案：CMS-0099638 PI：Dorothy Reed机构：华盛顿大学日期：2001年5月22日摘要CMS-0099638“城市地震中心电力设施生命线的性能”PI：Dorothy Reed，华盛顿大学。由于放松管制，美国的公用事业基础设施系统正在发生重大变化。最近，结构组件故障引起的自然灾害以前被认为是轻微的，造成了广泛的停电。由于自然和人为原因造成的电力短缺对太平洋西北地区的影响尤为严重，因为遵守环境标准对发电造成了限制。 很明显，美国缺乏一个统一的方法来提高电力基础设施的可靠性。 这样一个框架将有助于确定系统组成部分的重要性，并最终为改进业绩提供指导方针。我们建议开发一个基于可靠性的框架，电力公司的配电系统的地震灾害的性能评估。配电系统被定义为包括诸如配电线路、杆、基于杆的设备和变电站的组件。我们的框架将侧重于用于提供电力的结构系统的性能及其与其他关键生命线的相互作用。 我们的方法将显着扩展由日本岐阜大学的Nojima开发的三管齐下的模型，其中组件，系统和社会绩效指标混合成一个单一的标准。从兵库县南部（科比）和尼斯夸利地震中吸取的宝贵教训也将纳入我们的调查。这项调查将需要在目前美国社会经济、监管和政治气候的背景下制定拟议的绩效水平。 我们的项目的一个主要贡献将是明确包括，并最终澄清，法规的非技术约束的作用，并在这样做，隐含的政治气候的条件影响后，美国的位置性能水平的发展。虽然我们将专注于美国境内的特定地区[太平洋西北部]，但我们的方法在美国其他地区的适应应该是直截了当的。
