Description

technical field [0001] The patent of the invention belongs to the technical field of online monitoring of intelligent distribution network, mainly relates to the research of communication technology for online monitoring of distribution network lines, and proposes a method and device for on-line monitoring of distribution lines in passive coupling communication mode. Background technique [0002] At present, my country's transmission line technology is developing rapidly, and online monitoring technology is relatively mature. The operation safety and reliability of transmission lines are much higher than those of distribution lines. The ability of distribution lines to resist natural disasters such as ice, snow, and strong winds is relatively weak, and the fault query time is long, which affects the reliability of power supply. This requires us to develop intelligent power distribution technology to realize distribution line status evaluation, fault diagnosis, status Mainten...
