Electrical Transmission and Substation Structures 2022
Is My Substation Ready for the Next Extreme Event?
Publication: Electrical Transmission and Substation Structures 2022: Innovating for Critical Global Infrastructure
ABSTRACT
Keeping an electrical substation operational is one of the top priorities for every utility. In recent years, severe weather-related and extraordinary events have occurred more frequently, e.g., floods, hurricanes, tornados, and tsunamis. For substation structural designs, utilities often refer to ASCE 113, which is generally based on ASCE 7-05 edition with modifications to better suit substation designs. Although ASCE 113 provides guidelines on extreme conditions, such as high wind and seismic, there are no provisions on other extreme events. In this paper, load determinations for different extreme events, including hurricanes, tornados, and tsunamis, are first described based on various available resources. Then, how extreme event loadings are combined with all other applicable loads is presented. Several suggestions that may be applicable to substation applications are also provided. The goal of this paper is to provide utilities with a better awareness on extreme event loadings that could affect how utilities perform substation designs and allow them to better prepare, harden, and protect their assets during extreme events.
