New Offshore Wind Turbine Breaks Rotor Diameter World Record
19th October 2022
China News Service, Fuzhou, October 13 (Reporter Long Min).
On the morning of the 13th, in the Fujian Three Gorges Offshore Wind Power International Industrial Park located in Fuqing City, Fujian Province, Goldwind's 13.6 MW large-capacity offshore wind turbine was officially rolled off the assembly line. This is the wind turbine with the largest impeller diameter in the world and the largest single-unit capacity in the Asia-Pacific region.
In June 2015, China Three Gorges Corporation signed a strategic cooperation agreement with Fujian Province. Over the years, the Three Gorges Group has played the role of the "chain leader" in the industrial chain, and has joined hands with leading enterprises in the offshore wind power industry chain such as Goldwind Technology and Dongfang Electric, using the Fujian Three Gorges Offshore Wind Power International Industrial Park as a cooperation platform and carrier, and united with relevant provincial enterprises. Build Fujian offshore wind power industry cluster and jointly promote the upgrading of offshore wind power high-end equipment technology industry.
Lei Zengjuan, Executive Director and Secretary of the Party Committee of the Three Gorges Group Fujian Energy Investment Company, said that the current Fujian Three Gorges Offshore Wind Power International Industrial Park has become the "source" of China's original offshore wind power technology, forming a complete set of wind turbines, motors, blades, and steel structures. industrial chain. Here, Goldwind and Dongfang Electric have successively rolled off large-capacity offshore wind turbines of 6.7 MW, 8 MW, 10 MW and 13 MW independently developed by China. The launch of Goldwind's 13.6 MW unit this time marks another important breakthrough in the R&D and manufacturing capabilities of high-end equipment in the Fujian Three Gorges Offshore Wind Power International Industrial Park, and a larger MW unit will be rolled off by the end of this year.
According to Zhai Endi, chief engineer of Goldwind Technology, the offshore wind turbine with a single capacity of 13.6 MW is independently developed by Goldwind Technology and has completely independent intellectual property rights. It inherits the design of direct drive permanent magnet motor + full power converter , the scheduling response is more efficient, the power regulation is more accurate, the fault ride-through is smoother, and the grid connection characteristics are more friendly. The diameter of the impeller is 252 meters, and the swept area of the impeller is about 50,000 square meters, which is equivalent to 7 standard football fields. At full wind speed, a single unit can generate 29 kWh of electricity per revolution, and can output 63.5 million kWh of clean electricity every year, which can reduce coal consumption by 19,000 tons and carbon dioxide emissions by 48,000 tons, which can meet the requirements of 32,000 tons. A family of three has normal electricity consumption for one year.
Fujian Province is located on the west coast of the Taiwan Strait. Affected by the "narrow tube effect", the annual average wind speed at sea can reach about 9 meters per second, and the offshore wind resources are at the forefront of the country and the world. In addition, Fujian Province is also the starting point of the Maritime Silk Road, and has the geographical advantage of radiating Southeast Asia and facing the world.
In the context of the gradual realization of "parity" and "bidding" of offshore wind power to the Internet, the R&D and manufacturing of large-capacity offshore wind turbines is indispensable. As a leading enterprise in wind power equipment manufacturing, Goldwind is adhering to the drive of innovation, tackling core technologies, catching up with the world's first-class, and accelerating the research and development of large-capacity units to consolidate and expand technological and cost advantages, so as to develop offshore wind power into the deep sea and participate in the global The development of offshore wind power resources provides strong product support.
Lei Zengjuan said that during the "14th Five-Year Plan" period, the Three Gorges Group will continue to join hands with outstanding enterprises such as Goldwind Technology, adhere to the cooperation model jointly determined with Fujian Province to promote industrial development through resource development, and promote resource development through industrial development, and insist on innovation. Drive and green development, vigorously support the advanced equipment manufacturing industry and the real economy, increase the promotion and use of high-end products that are energy-saving, emission-reduction, green and low-carbon, and help the green transformation of local economic and social development.
