The 123-meter ultra-long blade, the world's longest wind turbine blade, produced by Zhongfu Lianyungang, a company based in Lianyungang, Jiangsu province, has started offshore installation at Pingtan wind Farm in Fujian province. It is China's longest wind turbine blade in the installation stage and will be used in the world's first super-capacity 16 MW offshore wind turbine.
"At full wind speed, the unit can generate 34.2 kilowatt-hours per rotation, equivalent to the average electricity consumption of a family of three in a week." Qiao Guanghuang, secretary of the CPC Committee and Chairman of Zhongfu Lianzhong, said that in today's fierce competition in the global wind power market, the upsizing of blades not only helps to improve the efficiency of wind power generation, but also reduces the location and cost of wind farms, so as to economically and efficiently serve the domestic "dual carbon" demand.
The 123-meter wind turbine blade produced by Zhongfu Lianzhong can accommodate 300 adults standing side by side at the same time. If the three blades are assembled together, the diameter of the entire impeller will reach 252 meters. The swirling sweep is the size of seven football fields.
It's not just bigger, it's bigger. It is reported that the blade inside the main beam structure breakthrough using carbon fiber material, weight reduction of 20%. In addition to a very small part of the raw materials from overseas, more than 96% of the materials of this blade have been made in China, and the technical process has 100% independent intellectual property rights. In addition, after the 16-megawatt offshore wind turbine adapted to the blade is connected to the grid, it will not only become the largest offshore wind turbine in operation in China, but also once again improve the latest technological level of China's offshore wind power equipment.
The difficulty of making such a big guy can be imagined. As a leading wind power blade manufacturer in China, in recent years, Zhongfu Lianzhong has been laying out new materials, new technologies, new processes and new equipment for ultra-large blades in advance. From 102 meters, to 110 meters, 112 meters, and then to 123 meters, Zhongfu Lianzhong continues to break its own manufacturing records, and become the world's more than 100 meters of blade service customers, manufacturing models of blade manufacturers.
The lifted leaves are 123 meters long, with a single mass of more than 50 tons, a root diameter of more than 5 meters, and a surface area of more than 1,000 square meters." Liu Sansheng, deputy general manager of Zhongfu Lianzhong, introduced that in order to complete the manufacturing, the R&D team of the enterprise carried out simulation prediction on the deformation of the leaf root and then carried out support optimization. The manufacturing team simulated each production link to make the production of relevant components and blades unimpeded, while using the perfusion technology accumulated over the years to achieve perfect perfusion of super-large area and ultra-thick parts.
