United Power self-made UAV innovates the inspection mode of wind turbine blades

It is reported that the "drone" independently developed by the employees of Guodian United Power Star Company successfully completed the inspection of MG17# wind turbine blades on the site of Mahuangshan on August 24, creating a new mode
of inspection work.

The traditional wind turbine blade inspection mode mainly relies on inspectors to use telescopes, spider people, hanging baskets, return platforms, etc.
to observe, and judge whether there is an abnormal situation
based on experience.
This mode not only has problems such as poor safety, large workload and low efficiency, but also is affected by the observation angle, resulting in the inability to fully and timely discover blade problems
.
"UAV" blade inspection refers to the use of UAV as a carrier aircraft, equipped with special imaging equipment for blade inspection to observe the surface state of the blade at close range, so as to achieve the purpose of
replacing manual inspection.
The use of "drone" for blade inspection takes only 20 minutes, compared with the traditional blade inspection mode, the single-phase project saves up to 264 hours of power generation time, and can also detect wear that cannot be observed during manual inspection
.

During the "drone" blade inspection, the driver will observe the surface status of the blade through the real-time data displayed by the ground station, and when suspicious points are found, the remote operation inspection equipment will be further inspected in detail, and high-definition pictures
from all angles will be collected.
These high-definition image data from different angles are summarized and sent to the blade experts through the software platform, and the experts judge and analyze, which makes the diagnosis of the problem more reliable and effectively avoids the influence of
human factors.
In addition, the high-definition image data collected by the UAV blade inspection will be retained for a long time, which is convenient for comparison with the historical inspection data after each blade inspection work, providing valuable data
for the tracking mechanism of the whole life of the blade.
In addition, the use of "drone" for blade inspection can quickly inspect the wind turbine nacelle, cabin accessories and tower during the inspection process, and it is easy to find problems such as loose bolts, equipment oil leakage, and paint loss of tower barrels, which is more efficient
than manual inspection mode.

Nowadays, the traditional blade inspection mode in the industry has been completely subverted by the "UAV" blade inspection mode, creating a safe, efficient and high-quality blade inspection new way
in the industry.
In the next step, United Power will further improve the "UAV" inspection mode, and continue to apply it to the wind power projects of the group company, and gradually make the "UAV" inspection a new trend
leading the maintenance service in the wind power industry.
