Seismic Performance and Damage Assessment of Electrical Substation
Publication: Earth and Space 2021
ABSTRACT
The seismic performance and damage assessment of electrical substation involving dynamic interaction between main structure and electric equipments are studied systematically. Specimen of a real substation with the scale of 1:8 had been tested on the shake table to investigate the effect of seismic performance of structure and electrical equipments. After that, a simplified numerical method based on ABAQUS is proposed to determine the damage of the cracked specimen. From experimental and numerical investigations, it is found that (1) the interaction of structure and electrical equipments is obvious in electrical substation; (2) the horizontal acceleration of the electrical equipments are larger than the structure, which means dynamic effect caused by electrical equipments should not be ignored in the seismic design of substation; (3) the damage assessment model is proposed, which is effective to assess the damage of substation; and (4) the simplified numerical method is proven to determine the seismic performance of large substation rationally.
