Resilience of Electric Power Substation Equipment

Resilience of Electric Power Substation Equipment Flyer (PDF)

MCEER’s multi-year effort to evaluate and improve the resilience of current and future electric power substation equipment has resulted in a series of recommended changes to the IEEE Standard 693-2005 - IEEE Recommended Practice for Seismic Design of Substations. Research work focuses on identifying the shortcomings of current design practices and developing new standards for qualification testing of seismically vulnerable substation equipment, primarily transformers and bushings.

The studies are supported by $1.2 million from the Bonneville Power Administration (BPA) and the California Energy Commission (CEC). The research continues a long-time MCEER focus on the seismic resilience of electric power substation equipment. The projects are led by Andrei Reinhorn, in collaboration with Andre Filiatrault and Michael Constantinou, all from the Department of Civil, Structural and Environmental Engineering at the University at Buffalo. They also include a project advisory committee comprising industry participants that provide continuing guidance to the research program.

Individual projects focus on the following:

The new recommendations have been submitted to the California Energy Commission’s Public Interest Energy Research (PIER) Program as a final project report authored by the team members.

The IEEE Standard 693-2005 discusses seismic design recommendations for substations, including qualification of each equipment type. Design recommendations consist of seismic criteria, qualification methods and levels, structural capacities, performance requirements for equipment operation, installation methods, and documentation.

Electrical Utilities Consortium

The MCEER Electrical Utility Consortium (EUC) was created in response to the needs of electrical utilities and focuses specifically on the seismic behavior of electrical substation equipment. The EUC was established through collaboration with and matching funds from the Electrical Power Research Institute (EPRI), which regroups electrical utilities in North America (US, Canada and Mexico). The Consortium investigates unresolved issues related to the IEEE-693 Standard on Recommended Practice for Seismic Design of Substations.

Research involves shake table testing of large and potentially vulnerable substation equipment such as transformer bushings and disconnect switches.

A technical oversight committee sets overall strategy, goals and schedule for the EUC research program. The committee is composed of one representative from each participating utility.
