Analysis of Electric Circuit in 1000kv Uhv Substation on Anti-Seismic and Wind-Resistance Performance
Abstract eng: A numerical model of electric loop in 1000 kV UHV substation has been developed. The mechanical property of electric loop has been studied under earthquake excitation with peak amplitude of 0.2g (g is the acceleration of gravity) and 31.2 m/s strong wind condition. The max stresses of components have been obtained for different loading combinations. The results show that the max stress of electric equipment occurs near the base. Additionally, the safety margin can meet the requirements of relevant codes. The finite element analysis indicates that porcelain bushings have significant difference in dynamic responses. In order to optimize stress distribution of the electric equipment, suggestion on section design of porcelain bushing has been made in this paper.
