Rapid Prediction Method of Seismic Response in Seismic Correlation Section of Electrical Equipment in Substation Based on Kriging Model
摘要
Abstract
The seismic response analysis efficiency of seismic correlation section of electrical equipment of substa-tion is low due to nonlinear structure of flexible structure of substation.In order to improve the correlation analysis ef-ficiency of electrical equipment of substation,a Kriging model for predicting the mean value and variance of seismic response of seismic correlation section based on the numerical analysis model of electrical equipment seismic correla-tion section is set up.On this basis,the normality test of the seismic response results of the seismic correlation sec-tion is performed,the selection method of Kriging correlation function based on semi-variance analysis is proposed,and the statistical value prediction of the seismic response of the seismic correlation section of electrical equipment with different vertical span ratio of flexible wires is developed.The study results show that using Gaussian model as the correlation function of Kriging model can better predict the seismic response of the correlated section,and Krig-ing model can better predict the seismic response of the flexible wire-electrical equipment seismic correlation section with strong nonlinearity,which can greatly improve the seismic response analysis efficiency of electrical circuit of substation and reduce the analysis cost.关键词
