基于相空间的励磁涌流新特征分析
A Novel Characteristic of Magnetizing Inrush Current Based on Phase Space
摘要
Abstract
A new characteristic based on phase space theory to identify magnetizing inrush current is introduced.' By reconstructing phase space with chaotic time-series, the one-dimensional single current sampled signal is mapped to a hyper- space to become hyperdimensional; meanwhile, the phase locus indicates the difference between inrush current and inner fault current. Simulation results show that it is possible to reconstruct a similar phase space under variable cases, and the phase locus of inrush current is very different from that of inner fault current.关键词
