The application of UAV in the field of new energy

First, the application of drones in the field of wind power

For the wind power industry, the first application scenario of drones is for the pre-planning site selection and survey and design, that is, the use of high-definition pictures taken by drones to generate corresponding 3D models to provide accurate data support for designers; Another major application scenario is operation and maintenance inspection, which can be used for blade inspection, which greatly reduces the risk of manual inspection and improves the inspection efficiency.

The visual technology can track the blade, identify the position of the blade in real time, and then accurately control the pT-head camera to complete the segmented shooting of the blade. After the shooting is completed, a complete large picture of the blade can be splicing. To provide customers with accurate and detailed detection results, the UAV can realize automatic flight, the detection process does not need human control, manual operation APP to complete the one-click start, the UAV automatically through the path planning input in advance to achieve real-time shooting, complete the entire blade detection task.

Second, the application of drones in the field of photovoltaic

Drones are also used in the full life cycle of photovoltaic systems, such as early investigation and design, late evaluation and acceptance and operation and maintenance inspection. With the progress of related technologies and the deepening of practical exploration, the advantages of UAV operation efficiency, operation accuracy and standardized operation will become more and more prominent. The UAV is equipped with visible light and infrared cameras, which can automatically carry out path planning to realize automatic inspection of the power station and fixed-point inspection of suspected faults.

The fault is determined by thermal location, including the abnormal temperature caused by component no power generation, hidden cracks, cloud cover, dust adhesion, scratches on the backplane, and component damage. The intelligent inspection and diagnosis software can process a large number of visible light and infrared photos collected by the UAV, realize image positioning, fault spot identification, and finally form a diagnostic report.

Third, the application of drones in the line

The UAV is mainly used in inspection and line erection.

In the traditional transmission line inspection, manual inspection is mainly used, that is, with the help of inspectors' naked eyes, infrared thermal imager and telescope and other equipment to directly observe the appearance and heating condition of the detection of the transmission line, and can use the rangefinder to determine whether the safety distance of the transmission line meets the safety norms and requirements. However, the manual inspection method will be limited by the detection equipment used and the terrain where the transmission line is located, which will affect the smooth development of transmission line inspection. If the transmission line inspection can be carried out by UAV, it can effectively make up for the shortcomings of traditional manual inspection.

In the process of traditional transmission line erection, manual erection is mainly adopted, but this mode of transmission line erection will consume a lot of labor costs, the construction period is relatively long, and the risk of line erection is relatively large. Even if the wiring methods of airship and power umbrella were introduced in the place where the manual wiring was difficult a few years ago, the former has poor mobility, high price and insufficient popularity; The risk factor of the latter is relatively large, and it is not suitable for promotion and popularization. If the UAV can be reasonably introduced to carry out the wiring operation in the process of transmission line erection, it can inject new vitality into the construction of China's power grid, improve the quality, efficiency and safety of transmission line erection, and also help reduce the damage to forest resources.

Fourth, the future prospects of UAV application

First, intelligent flight, the use of 4G and Beidou satellite navigation to achieve remote control of drones, drones can be understood as flying smart phones, similar to the development of smart phones, drones shorter endurance and other problems can certainly be solved in the future;

The second is the group operation, a variety of UAVs fly at the same time, improve the efficiency of inspection, line construction and other operations;

Third, autonomous flight, the full autonomous flight of drones will be more widespread than self-driving cars;

The fourth is intelligent fault identification, using deep learning technology to achieve intelligent identification of subsequent images, pictures and faults. Most of the current drones can only collect data and rely on manual post-processing data, which is not efficient enough. In the future, real-time data processing can be realized through artificial intelligence technology and completely replace human operation and maintenance.
