摘要
由于现有的直流供电系统接地故障检测有一定的缺陷,通过混沌动力学分析故障检测的两种方法结合对直流供电系统接地故障进行研究,即系统固有的混沌特性和加入混沌振子子检测系统,仿真结果表明,此新方法有较好的准确性。
The DC power supply methods for fault detection through system of the existing grounding fault detection has some shortcomings, two kinds of the chaotic dynamics analysis of a comprehensive study of the grounding fault in DC power supply system, namely chaotic characteristics of the system inherent and join the chaotic oscillator sub detection system, the results show that compared with the existing detection systems have a certain to improve.
