摘　　要：交联聚乙烯(XLPE)电缆已广泛应用于电力系统。为确保电力系统安全稳定的运行,电力部门迫切要求进行XLPE电缆绝缘状况检测及老化诊断。本文构建了双耦合Duffing混沌振子检测模型,基于Matlab-Simulink仿真平台研究不同传播距离的局放检测信号的混沌特征参量的变化情况,采用XLPE电缆进行了放电信号传输实验,通过仿真实验双向论证电缆传播中局放衰变的规律。Cross linked polyethylene（XLPE） cables have been widely used in electric power system. In order to ensure the security and stability of power system operation, the electricity sector is pressing for a XLPE cable status detection and diagnosis of insulation ageing. The paper establishes a double coupled Duffing chaotic oscillator detection model, changes of chaotic characteristic parameters of the simulation platform of Matlab-Simulink at different distances from the PD signal detection based on the XLPE cable, the discharge signal transmission experiment, through the simulation experiment of;cable transmission of bidirectional partial discharge decay law.
