Problems solved by technology
[0005] Embodiments of the present invention provide a system and method for measuring icing on the ground wire 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. There are various indirect measurement methods that also make the results of ice measurement not accurate enough

The present invention provides an overhead power transmission line conductor ground wire ice coating measurement system and method, which belong to the power transmission line measurement technical field. In the system, the lower end of a multi-rotor flight device is connected with an electromagnetic wave measurement device. A flight device controller transmits a flight control instruction to themulti-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 a measurement instruction to the electromagnetic wave measurement device; the electromagnetic wave measurement device transmits electromagnetic wave signals to the iced overhead power transmission line conductorground wire and receives electromagnetic wave reflection signals; intermediate frequency processing signals are formed and transmitted to a ground monitoring device; and according to the intermediatefrequency processing signals, the ground monitoring device determines the ice coating thickness of the overhead power transmission line conductor ground wire. Thus, the problems of complexity and dangerousness of existing ice coating measurement modes most of which require operators to carry a measurement 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 wires 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 transmiss...
