Galveston Island (TX) Electric Power Network Data

Galveston Island is a barrier island in the Texas coast approximately 50 miles away from Houston. This island has been historically impacted by hurricane/storm events such as Hurricane Ike in 2008. The goal of this project is to build an inventory for the island's electric power network (EPN) as a part of the Galveston Testbed for the NIST funded Center of Excellence (CoE) for Risk Based Community Resilience Planning. The inventory data for the transmission and distribution networks of Galveston Island was developed using publicly available data sources, along with post-processing, expert judgement, and inference. The EPN inventory data comprises the following items: a) Distribution system point data including the location, class, height and span length for wood poles. b) Distribution system connectivity including overhead and underground lines. c) Transmission system data including the location of towers and the location of prestressed concrete poles. d) Transmission system connectivity. e) The location of substations. This data is designed to be used along with the wind-surge-wave fragility functions proposed by the authors found in the following paper: Darestani, Y., Padgett, J. and Shafieezadeh, A., 2022. Parametrized Wind–Surge–Wave Fragility Functions for Wood Utility Poles. Journal of Structural Engineering, 148(6), p.04022057. https://doi.org/10.1061/(ASCE)ST.1943-541X.0003319. Developed as a part of a broader CoE Tesbed effort, this dataset is intended for use within the Interdependent Networked Community Resilience Modeling Environment (IN-CORE).

加尔维斯顿岛（Galveston Island）是坐落于德克萨斯州海岸的障壁岛，距休斯顿约50英里。该岛历史上曾受2008年艾克飓风（Hurricane Ike）等飓风及风暴事件的冲击。
本项目旨在为该岛的电力网络（Electric Power Network, EPN）构建清单，作为美国国家标准与技术研究院（National Institute of Standards and Technology, NIST）资助的基于风险的社区韧性规划卓越中心（Center of Excellence, CoE）加尔维斯顿测试床的组成部分。
加尔维斯顿岛的输电与配电网络清单数据，通过公开数据源结合后处理、专家研判与逻辑推演开发完成。该电力网络清单包含以下内容：
a) 配电系统点数据，涵盖木质配电杆塔的位置、类别、高度与档距；
b) 配电系统拓扑连接关系，包含架空线路与地下线路；
c) 输电系统数据，包括铁塔位置与预应力混凝土杆塔位置；
d) 输电系统拓扑连接关系；
e) 变电站位置。
本数据集配套作者团队于2022年发表的论文中提出的风-潮-浪易损性函数使用，相关文献信息如下：
