Shanxi's power grid is one of the most complex in the country, with 70 percent of its lines in mountainous areas and nearly 65 percent of its lines in mountains and mountains, which are inefficient because of manual inspection.

In 2023, Shanxi Electric Power has realized full coverage of autonomous UAV inspection in the main network. However, due to problems such as endurance time and flight distance, inspection personnel are still required to arrive at the site before they can carry out work. In the distribution lines facing the cross-mountain area, operation and maintenance personnel are "powerless". For this reason, Shanxi Power Grid actively carries out the deepening application of various types of UAV inspection. Considering various comprehensive factors, Shanxi Power Grid vigorously promotes the installation and use of UAV intelligent nest.

China News did a special report on this issue.

In order to comprehensively improve the fine management level of Shanxi power grid, improve the quality and efficiency of transmission line operation and maintenance. Shanxi Power Grid adopts the unsupervised innovation measures, chooses to build Honeycomb Aerospace SU-30 intelligent unmanned airport, expands the application scenario of digitalization in power grid management, the UAV automatically executes airline tasks, realizes the full coverage of inspection scope, effectively identifies all kinds of anomalies, and extends the antenna of power grid management inspection into each grid, aiming at problems and sending force accurately. Opened a new mode of unattended power grid inspection.

Compared with the traditional manual operation mode, Honeycomb Aerospace SU-30 intelligent unmanned airport truly realizes "unmanned". It relies on autonomous flight of UAV to complete the fine inspection work of the tower and tower, realize field deployment and unattended, and significantly improve the inspection efficiency. At the same time, the autonomous inspection mode is not affected by the geographical environment, so as to better guarantee the personal safety of operation and maintenance personnel.

When the operator gives instructions from the control platform, the UAV takes off from the automatic airport, quickly arrives at the scheduled tower, accurately identifies and locates various anomalies according to the planned inspection path, completes the inspection of the first base tower, and automatically flies to the next tower without any operation. After the UAV completes all inspection tasks, it will automatically return to the UAV hangar and automatically charge to wait for the next inspection task.

The overhead lines of the power grid are generally located in remote areas with a long distance from the command center. SU-30 intelligent unmanned airport uses 4G/5G network for data transmission, and the transmission distance is not restricted, and it is not blocked by obstacles. Operators do not need to go to the site, but can remotely control the UAV on the visual interface and grasp the status of inspection in real time. The remote visual management of transmission lines can be realized to improve the safety management level of power grid.

The traditional mode of "human patrol + aircraft patrol" is mainly completed by on-site operation and maintenance personnel, which is characterized by heavy workload and tedious work of production site personnel, and the precision of inspection is completely maintained by personnel's skill level and sense of responsibility. However, there are many blind spots in inspection because the inspection work is complicated and cannot be fully taken into account. Moreover, due to the poor timeliness and low closed-loop degree of field personnel feedback and problem handling, many problems still exist in more work. Therefore, the remote, digital and intelligent management mode based on SU-30 intelligent unmanned airport can make up for various problems existing in field and operation.

Power grid security is related to economic and social development and public security, and is the "lifeline" of the development of State Grid Corporation. Honeycomb Aerospace intelligent unmanned Airport helps Shanxi Power Grid to build autonomous UAV inspection application, improves the safe operation level of power distribution lines, realizes the standardization and normalization of power grid inspection, and effectively improves the quality and efficiency of power grid operation and maintenance.
