Chaotic characteristic analysis of arc voltage based on phase space reconstruction and Lyapunov exponent
摘要
Abstract
Series arc fault is the key cause of electrical fire.In order to obtain reliable data sources and a more comprehensive understanding of the characteristics of arc fault voltage,the experimental platform of actual electricity environment arc fault is set up according to the UL1699 and GB14287.4 standards.Depending on the experimental results,the arc voltage signal is introduced into the high dimensional space by using the phase space reconstruction algorithm,and the two-dimensional phase diagram of different load is made.Otherwise,the maximum Lyapunov exponent of series arc voltage signal is calculated by using the small-data method.Based on the comprehensive analysis of the phase trajectory distribution rules and the maximum Lyapunov exponent,the chaotic characteristic of fault arc voltage was proved.The research results not only enrich the characteristics of the arc voltage signal,but also provide theoretical guidance for design of arc model and electric fire monitoring detector.关键词
