基于电力线通信的电缆智能诊断(一):含异常的高频信道传输模型
Intelligent Cable Diagnosis Based on Power Line Communication(Part Ⅰ):High-frequency Channel Transmission Model With Anomalies
摘要
Abstract
Power line communication and power frequency energy transmission share the same medium,and there is a natural and close connection between the two.As a carrier of high-frequency communication signals,the subtle dynamic changes in the physical properties of power lines will significantly affect the transmission characteristics of broadband communication signals.However,the lack of a clear model for the high-frequency channel characteristics of power lines with complex abnormal conditions has hindered the development of new cable state reverse detection technologies.This paper proposes a fusion strategy and modeling method of cable aging parameter model and power line channel model,which realizes the modeling of power line channel transmission characteristics of cables under different aging states.Starting from the mechanism of cable insulation aging,the generation and evolution path of aging phenomena were analyzed,and then a hybrid tree branch aging model and thermal aging model were constructed.The cable aging parameter model and the channel model are integrated to establish a power line channel transmission model that can reflect aging and abnormal effects.This study provides a theoretical framework and practical guidance for a deeper understanding of cable aging processes,how to subtly reshape channel characteristics,and how to use relevant theories for accurate prediction and detection of cable aging in engineering practice.关键词
