Abstract
Power grid is an important part of the earthquake lifeline project. As electrical substation is the node of the power grid, and the safety evaluation of the substation under earthquakes is essential. There are a wide variety of electrical equipment in substations, and multi pieces of equipment are interconnected to form the complex circuits. Seismic modelling of substation equipment requires engineering researchers to have an accurate understanding of the structure of electrical equipment, as well as to collect complete electrical equipment structural parameters. This process takes a lot of time and effort. This paper proposed a parametric modelling method for substation equipment, which can achieve effectiveness in seismic modelling. Parametric modelling and seismic analysis of high-voltage equipment of a 220 kV substation in Xinjiang is carried out, which verified the validity and applicability of the method.
