An online intelligent monitoring method of transmission line status in smart grid based on big data analysis

Abstract

The invention discloses an online intelligent monitoring method for the status of transmission lines in a smart grid based on big data analysis. By dividing the transmission lines in the distribution network into sections of transmission lines, the insulation surface of each section of transmission lines in the distribution network is collected. Image, obtain the damaged area of ​​the insulation skin in the insulation surface image of each section of the transmission line in the distribution network, calculate the actual damaged area of ​​the insulation surface of each section of the transmission line in the distribution network, and obtain the transmission line of each section in the distribution network. The number of broken wires in the electronic circuit, and measure the height of the line at the center point of each section of the transmission line in the distribution network, compare and analyze the line height difference at the center point of each section of the transmission line in the distribution network, and calculate the distribution network. The comprehensive safety impact coefficient of each section of the transmission line in the power grid analyzes whether each section of the transmission line is in a dangerous stage, and repairs or replaces each section of the transmission line in the dangerous stage, so as to ensure the safe power supply of the distribution network.

Problems solved by technology

[0003] At present, most of the existing transmission line status monitoring technologies in the distribution network use manual monitoring, that is, manual monitoring of the transmission line status in the distribution network at regular intervals to find potential safety hazards in the transmission line in the distribution network, which not only wastes a lot of human resources, but also In addition, there are problems such as uneven personnel knowledge reserve, uneven experience and ability, and different reference standards, which lead to a decrease in the accuracy of monitoring data, thereby reducing the reliability of power supply in the distribution network. In the state of broken wires, there is a lag in monitoring information, which leads to the inability to effectively and targetedly deal with the transmission lines in a timely manner, which affects the safe power supply guarantee of the distribution network, and thus cannot meet people's electricity demand. In order to solve the above problems , an online intelligent monitoring method for transmission line status of smart grid based on big data analysis is now designed
