Problems solved by technology

[0004] The dense and complex distribution of AC and DC circuits in the environment of key transmission channels makes it more difficult to identify and track hazards in the channel than ordinary transmission channels; at the same time, key transmission channels need to be protected against lightning strikes and external damage (mountain fires, construction damage) in real time. , anti-tree (bamboo) line discharge), anti-pollution flashover, anti-bird damage, anti-icing, anti-wind deflection work, if the key transmission channel management and control work is placed in the unified management of the power grid management and control system, It may cause inefficiency in the management and control of key transmission channels, and it is impossible to realize timely early warning of failures. Therefore, an intelligent analysis and control method based on the operating characteristics of key transmission channels is urgently needed

Abstract

The invention discloses a power transmission channel control method. The method comprises the following steps that laser point cloud data and cruise image data of a power transmission channel and video data shot by video equipment installed on the power transmission tower of the power transmission channel are collected, the three-dimensional model of the power transmission channel is modeled on the basis of a laser point cloud data line, and the three-dimensional model comprises a meteorological model established on the basis of meteorological data, operation and check data is input to the three-dimensional model for data storage, fusion, computing and analysis, wherein the three-dimensional model achieves transmission video image active early warning based on cruise image data and video data, and the three-dimensional model dynamically analyzes and calculates sag, windage yaw and tower stress based on laser point cloud data and the cruise image data.

Description

technical field [0001] The invention belongs to the technical field of power transmission line management and control, in particular to a power transmission channel control method. Background technique [0002] In recent years, with the continuous commissioning of the DC projects of the State Grid, it has become more and more common for DC transmission lines and AC transmission channels to be shared in the power grid, resulting in the dense arrangement of lines in the transmission channels of the power grid, and relatively large The power transmission channels with heavy loads are concentrated in the key transmission channels in a small narrow area. These critical channels face the risk of local disasters causing large power grid accidents. How to ensure the safe and stable operation of key transmission channels has become the basis for ensuring the electricity demand of users in various regions, and it is also the top priority of State Grid Corporation's safety production....
