基于多项式混沌方法的场线耦合响应不确定度量化
Uncertainty quantification analysis of random field coupling to transmission lines based on polynomial chaos expansion method
摘要
Abstract
Normally,transmission lines'uncertainty quantification analysis based on Monte Carlo (MC)method need very large number of samples.This paper chooses the polynomial chaos expansion (PCE)method to analyse the uncertainty quantifica-tion of random field coupling to transmission lines.In the case where input uncertain parameters are of non-typical distributions, the corresponding orthogonal polynomial basis is constructed and the telegraph equation by PCE method is expanded.Finally,the statistical information of far end current is computed in the case of random field with two uncertain parameters coupling to trans-mission lines.It is proved that the PCE method is valid and more efficient compared with MC method.关键词
