Seismic Risk Assessment of the Electrical Substations in Colombia of ISA, the Largest Energy Transmission Company of Latin America
Publication: Electrical Transmission and Substation Structures 2022: Innovating for Critical Global Infrastructure
ABSTRACT
This paper presents the seismic risk assessment of the electrical substations located in Colombia of ISA (Interconexión Eléctrica S.A. E.S.P), which is the largest energy transmission company in Latin America. Seismic forces are not usually considered in the design of the transmission lines as tension and wind are more critical loads. In order to perform the seismic risk analysis exposure, vulnerability and seismic hazard models were generated. Risk metrics such as average annual loss, the probable maximum loss, and loss values for different return periods are used to present the results of the risk assessment. In the interest of interpreting and visualizing more clearly the consequences of a particular seismic event, scenarios were selected in which the number and distribution of the collapse of the substation’s components and associated economic losses are calculated.
