A system and method for measuring icing on ground conductors of overhead transmission lines

Abstract

The present invention provides an overhead power transmission line conductor ground wire ice coating measurement system and method and belongs to the power transmission line measurement technical field. A multi-rotor flight device in the system is provided with an ultrasonic probe. A flight device controller transmits a flight control instruction to the multi-rotor flight device so that the multi-rotor flight device can be made to fly to an iced overhead power transmission line conductor ground wire; the flight device controller transmits an ultrasonic acquisition instruction to the multi-rotor flight device; the multi-rotor flight device acquires ultrasonic signals at the iced overhead power transmission line conductor ground wire through the ultrasonic probe and sends the ultrasonic signals to a ground monitoring device; and the ground monitoring device determines the thickness of the ice coating of the overhead power transmission line conductor ground wire according to the ultrasonic signals at the iced overhead power transmission line conductor ground wire. With the overhead power transmission line conductor ground wire ice coating measurement system and method of the invention adopted, the problem of complexity and dangerousness of existing ice coating measurement modes most of which require operators to carry measuring instrument to climb towers, and the low accuracy of results of indirect measurement modes can be solved.

Description

technical field [0001] The invention relates to the technical field of power transmission line measurement, in particular to a system and method for measuring icing on ground conductors of overhead power transmission lines. Background technique [0002] With the vigorous development of the State Grid, the current overhead transmission lines, as an important part of the power grid, have spread all over the country. As the climate continues to change, in addition to the severe freezing rain and snow weather in the northern part of my country, the southern part of China has also suffered from severe freezing rain and snow freezing disasters in recent years. When overhead transmission lines suffer from freezing rain and snow disasters, accidents such as line tripping, line disconnection, and tower collapse are prone to occur, which has a great impact and threat on the safe and stable operation of power systems and power supply across the country. The phenomenon of icing on tran...

Problems solved by technology

[0005] Embodiments of the present invention provide a system and method for measuring icing on conductors and ground wires of overhead transmission lines to solve the problem that most of the current icing measurement methods require operators to carry measuring instruments to climb towers for measurement, which is cumbersome, complicated and dangerous. And the way of indirect measurement also makes the result of ice measurement inaccurate.
