Recently, Dajiang industry officially released a new power grid application solution. The solution integrates a series of "fist products" under the application of Dajiang industry, including Dajiang airport, longitude and latitude M30 series UAVs, Sikang 2 UAV management cloud platform, Dajiang Zhitu route planning and modeling software, and comprehensively covers the working scenes of transmission and distribution line patrol inspection, substation patrol inspection, infrared patrol inspection, emergency repair and so on. It is committed to meeting the automation Intelligent line inspection needs and increasingly urgent digital transformation needs of the energy industry.
Transmission is an important part and foundation of power system operation. According to the structural form, transmission lines are divided into overhead transmission lines and underground lines. Among them, the overhead transmission line is composed of line tower, conductor and insulator, which is erected on the ground, which is the main form of transmission line at present. Overhead transmission lines have long distance and wide distribution, and the equipment is exposed to the natural environment for a long time. Due to the frequent exposure to rain, snow, freezing, pollution, lightning and other bad weather and the invasion of external damage such as tree dumping, bird and animal impact, overhead transmission lines have more chances of failure. In order to find the defects of equipment and the factors endangering the safe operation of the line in time, and ensure the safe and stable transmission, the overhead transmission line needs to be inspected frequently.
Before the emergence of UAV inspection technology, transmission line inspection completely depended on manual work. The line patrol personnel need to check each patrol point that may have faults one by one. On the one hand, due to the long distance and wide distribution of transmission lines, line patrol personnel need to work for a long time in the harsh environment in the field and carry out dangerous tower climbing and line routing operations, so the personal safety of line patrol personnel cannot be guaranteed; On the other hand, manual inspection is difficult, inefficient and inaccurate, and it is difficult to find subtle fault indications, which may lead to misjudgment of faults and bury major hidden dangers of faults. With the development and maturity of UAV patrol technology, this situation began to change.
In February 2020, the equipment department of the State Grid issued the notice on printing and distributing the key tasks of equipment management in 2020, which proposed to "strengthen the promotion and application of transmission line inspection UAVs" and "promote the visual construction of transmission line channels". After the introduction of the policy, power system enterprises have begun to layout UAV inspection operations. In September 2021, the State Grid announced that the large-scale application of independent inspection of State Grid UAV was officially completed and put into operation. In the future, a new mode of "three-dimensional inspection + centralized monitoring" equipment operation and maintenance management will be explored in the project operation.
The unmanned electromechanical network application solution released by Dajiang this time deeply integrates advanced technologies such as UAV, load, route planning and image processing with power application, which can carry out automatic and fine inspection of power grid facilities and surrounding environment, and solve the inspection problems of "wide overhead line coverage, complex infrastructure environment and long transmission distance" that have been perplexing power system enterprises, The accuracy and efficiency of transmission line inspection have been greatly improved, and the shortage of inspection human resources in power system enterprises has also been solved.
portable high-performance inspection scheme
The scheme is composed of Jingwei M30 series UAV, DJI pilot2 application and Dajiang Zhitu power version. It has three functional characteristics: easy to carry, adapt to severe working conditions and fully meet the needs of intelligent patrol inspection. Among them, the longitude and latitude M30 series UAV, as the "flagship aircraft installed in the backpack", can fly for up to 41 minutes, and has the working temperature design of - 20-50 ℃ and the protection grade of IP55 fuselage. It has good environmental adaptability and continuous operation ability. It is worth mentioning that the longitude latitude M30 series UAV is also equipped with a set of multi-in-one and highly integrated PTZ cameras, which supports low light intelligent photography and infrared thermal imaging, and can provide support for a variety of Ground Power Patrol scenes.
unattended patrol inspection scheme
The scheme is composed of Jingwei M30 UAV Airport Version, Dajiang airport and shangyun API expandable modules, which can realize 7 24-hour all-weather operation, realize the real unmanned operation function in many fields such as line channel inspection, equipment fine inspection and daily patrol, bring all-round efficiency innovation and comprehensively liberate productivity. It is worth mentioning that although the scheme is powerful, the deployment is very simple and convenient. The Dajiang airport with highly integrated design can complete the deployment only by ground fixation, power supply and network access.
For the release of solutions for Dajiang power grid industry, Lu Feng, director of Dajiang innovative energy BD, said: "The power grid industry is a key field for the long-term application of the power grid industry in Xinjiang. According to the statistics in 2020, the length of China's 110 kV transmission line has reached 650000 kilometers, which is backed by a large-scale UAV automatic inspection market. The release of this new power grid industry solution is another milestone for the application of the power grid industry in Xinjiang. Next, we will continue to combine the needs of customers in the power grid field In depth demand, through innovative technology research and development, the application scenarios of the solutions are expanded to power grid transformation, power grid infrastructure, power grid emergency security and other fields, providing support and assistance for promoting the digital and intelligent transformation of China's power grid industry and the construction of new power systems.
