In 2024, Germany was the European country with the highest electricity generation from wind energy – wind now produces 29 percent of the total gross electricity. Due to the fact that more electricity is generated in the north of the country than is needed there, north-south transmission is increasing and causing bottlenecks in the transmission lines. Their transmission efficiency is extremely dependent on weather conditions, so these have to be recorded as accurately as possible. This is done by sensor stations mounted on the power poles near the overhead lines to register solar radiation, air cooling and the like, and thus calculate the weather-dependent dynamic current-carrying capacity.
In order to quickly and safely mount sensors at great heights, researchers at KIT have developed an installation approach in which assembly and disassembly are carried out directly on the power pole using a drone. The drone is equipped with a gripper arm that carries an extension arm. Instead of screws, magnets and clamping mechanisms are used to attach the extension arm to the pole. The magnets align the extension arm with the power pole, and the clamps enclose it. The torque generated wedges the extension arm and holds it firmly in position. It features a kind of collection basket into which the drone can unload the sensor housing and from which it can pick it up again, for example to replace the batteries.
With the new installation concept, significantly more sensor nodes can be installed in the same period of time. For this, technicians do not have to be put in danger, nor do crane systems have to be provided, additional measuring poles have to be set up or lines have to be disconnected. The concept is not only interesting for grid operators and their measurement technology suppliers, but for all companies that want to attach sensors at inaccessible heights.
You can get an overview of this technology at the KIT stand. Details will be available after the trade fair.
