Stoen Operator scans overhead power lines

Stoen Operator is implementing an innovative project to create a 3D model of high-voltage overhead lines. In collaboration with Vimap, it scans the network from a helicopter. The information provided will be used to monitor hard-to-reach areas and increase energy sustainability.

  • The first stage of high-voltage overhead line scanning was carried out on October 1, 2021. The next flight is scheduled for the second half of 2022.
  • A technologically advanced system consisting of several measuring devices is used to scan the network configuration and the devices installed on it.
  • Stoen Operator mapped medium and low voltage overhead lines using unmanned aerial vehicles.

The first stage of high-voltage overhead line scanning was carried out on October 1, 2021. Equipped with a specialized network device diagnostic system, the helicopter mapped 90 km of the network, mainly in the eastern part of Warsaw, in one working day. The next flight is scheduled for the second half of 2022.

– At present, as part of the project, we have scanned a quarter of high-voltage overhead lines at once. Due to the characteristics of the Warsaw network, ie a relatively small network concentrated around the city, it is easier to scan. The only restrictions may come from areas such as airports or military areas that require special permits. For example, some of Stoen Operator’s high-voltage lines are close enough to Warsaw Okęcie Airport that flights over the area should be carried out in close contact with air traffic controllers, says Szymon Pomykała, Stoen Operator’s network standards specialist. .

Vimap specializes in mapping electrical networks. Thanks to reports from this company, the Warsaw distribution network operator shortens the time to update inventory. It will also expand the ability of field workers to assess the technical condition of out-of-sight elements, conduct network analysis for changing conditions (eg cable temperature), and even create tree fall simulations.

– We use different types of helicopters equipped with special measuring equipment to get information about the infrastructure. The configuration of the system installed in the helicopter is always adapted and adapted to the objectives of the project and the type of infrastructure tested. In addition to advanced equipment, the project includes our own special vMatic software to manage the supplied data. Provides visualization and integration of received data. In addition, this solution automatically detects close plans and very small distances with the given parameters – explains Krzysztof Tkocz from Vimap.

Innovative diagnostics

A technologically advanced system consisting of several measuring devices is used to scan the network configuration and the devices installed on it. High-resolution cameras capture individual infrastructure elements and take very detailed, high-quality photos, which are then processed with special software. In this way, it is also possible to quickly detect faults and violations that could lead to failures and interruptions in the power supply.

Thanks to the use of laser scanning technology (lidar), a 3D model of the line and its surroundings is created. Using a three-dimensional description of the area, photographs and analytical tools, it is possible to accurately identify areas where regulatory distance requirements are not met, such as in relation to trees or buildings. This information allows us to take appropriate technical measures to minimize threats to network security – reports Stoen Operator.

Working with Vimap does not stop your normal employee from visually inspecting. According to the company, it is better to assess the foundation and lower parts of the pole during pedestrian inspections of these devices once a year. On the other hand, helicopter scanning of the line allows a more accurate assessment of the condition of infrastructure elements that are out of sight of the field worker. Therefore, the best solution is to assess the technical condition of network devices in the hybrid model.

This is not the first high-voltage overhead line scan project. Stoen Operator has already mapped medium and low voltage overhead lines using drones. They have also been used as a support tool in the activities of the Emergency Service to assess emergencies and planned events in areas that are difficult for field workers to reach.
