Set Asia-Pacific single-unit capacity record, my country's offshore wind power enters the 10 MW era
Latest discoveries and innovations
Science and Technology Daily, Beijing, July 13 (Reporter Qu Jian) According to the latest news from the Three Gorges Group, at 21:25 on the 12th, the first domestic 10 MW offshore wind turbine was successfully merged with the Three Gorges Group Fujian Fuqing Xinghuawan Phase II offshore wind farm. Grid power generation. This is currently the largest single-unit capacity of the Asia-Pacific region and the second largest offshore wind turbine in the world. Since then, my country's offshore wind power has entered the era of 10 MW wind turbines with greater energy density.
According to Three Gorges Group, the 10 MW generating unit of this grid-connected power generation is the latest generation of large-capacity offshore wind turbines with complete independent intellectual property rights. It was jointly developed by the Three Gorges Group and Dongfang Electric Group. On September 25, 2019, Fujian Three Gorges Offshore Wind Power The International Industrial Park is offline. This type of unit is designed for Class I wind areas in Fujian, Guangdong and other sea areas. The unit's environmental adaptability, equipment reliability, and wind energy utilization rate have been greatly improved, and it has super typhoon resistance. The center height of the hub of the unit is about 115 meters from the sea level, which is equivalent to the height of 40 floors; the diameter of the fan impeller is 185 meters, which is equivalent to the width of 3 Boeing 747 side by side; the sweep area of the wind wheel is equivalent to 3.7 standard football fields. Under the condition of an average annual wind speed of 10 meters/second, a single unit can generate 40 million kilowatt hours per year, which can reduce coal consumption by 12,800 tons and reduce carbon dioxide emissions by 33,500 tons, which can meet the normal electricity demand of 20,000 families of three.
The Three Gorges stated that since the construction and operation costs of offshore wind power are much higher than those of onshore wind power, the promotion and use of 10 MW offshore wind turbines with larger capacity and higher energy density can greatly reduce the foundation, levy, installation, submarine cable and later stage. The cost of operation and maintenance promotes the reduction of the cost of offshore wind power and electricity, and effectively improves the market competitiveness of offshore wind power in the era of "parity grid"; at the same time, it also helps to reduce the sea area used by wind farms and increase the utilization rate of the ocean.
It is reported that the unit will be mass-produced after the trial operation of the Xinghua Bay Phase II project, and will gradually be promoted and applied in Fujian's million-kilowatt wind farm and a wider range of offshore wind farms at home and abroad, helping the Three Gorges Group to carry out 12 MW The above larger capacity offshore wind turbines are jointly developed.
