"Our drone inspection can be fully checked under the dynamic, slow and static state of the fan. Through intelligent analysis of potential defects, the inspection report can be quickly generated, which can shorten the downtime of equipment inspection and reduce power generation loss. Meanwhile, the inspection image data can be automatically synchronized to the cloud and the backstage storage server." Speaking of the drone inspection program, Zhang Yuchuan, a transport inspector at The Siziwangqi Maintenance Inspection Center of Inner Mongolia New Energy Company, is full of confidence.
As a post-90s, Zhang yuchuan has shown great interest in drones since his childhood. "When I was a child, I liked airplane models and often made them by hand. After I went to school, I fell in love with drones. My graduation thesis was about drones, and I joined Inner Mongolia New Energy Company with the idea of drone inspection." After coming to the company, Zhang Yuchuan, who majored in mechanical design, manufacturing and automation, actively explored the application of drone in the industry with the strong support of the company based on his professional expertise and work needs. "The traditional means of blade inspection is to use telescopes to observe on the ground and to detect the hanging basket, which is limited by equipment, Angle, scope and other factors, and has disadvantages such as low detection efficiency, high labor intensity, long detection time, high cost, unclear detection image, and often unable to find problems in a timely and effective manner. Comparatively speaking, uav patrol is not only time-saving but also more accurate."
The successful experience of siziwangqi Hydropower Station in using drone for patrol inspection has been highly valued by Inner Mongolia New Energy Company and even the State Power Investment Group Company. Relying on Siziwangqi Wind Power Station, in 2018, The State Power Investment Group officially established a staff innovation studio based on drone intelligent patrol. So far, it has obtained 8 patents and 4 patents under review.
Xue Huawu, executive director and Party Secretary of Inner Mongolia New Energy Company of State Power Investment Group, said that since 2018, the company has used drones to complete the inspection of all internal wind turbine blades, and carried out the quality assurance and acceptance work of Xinjiang Turpan, Jimunai and Beitashan wind power projects. A total of 1286 fan blades have been inspected. A total of 474 blade abnormalities and defects were found, and the working efficiency of a single blade patrol inspection was increased by more than 5 times. "Drones are also widely used in photovoltaic stations. So far, more than 40 photovoltaic stations have been inspected, covering Inner Mongolia, Ningxia, Shandong, Shanxi, Tianjin, Hebei and other places. More than 10,000 rows of problematic photovoltaic modules were found in total, which greatly enhanced the generating capacity of the station and reduced the loss." "Xue Said.
