Electrical Transmission and Substation Structures 2022
Damping Devices for Seismic Protection of Substation Equipment
Publication: Electrical Transmission and Substation Structures 2022: Innovating for Critical Global Infrastructure
ABSTRACT
Electric utilities play a pivotal role in disaster recovery. Long-term power outages will have a significant effect on the local and regional service area. From a resiliency perspective, electric power substations control the interconnected transmission and distribution lines, and points of generation and delivery. Past earthquake performance of the electric power grid has demonstrated that substation components are the most seismically vulnerable of the power delivery system. One solution for reducing the seismic vulnerability of both existing and new substation components is the application of supplemental damping devices. These devices have been used for substation equipment for decades, but on a limited basis. This paper will present past and present applications of substation equipment supplemental damping devices. Applications of supplemental damping device for three Utilities (Seattle City Light, Bonneville Power Administration, and San Diego Gas and Electric) are presented.
