On February 22, 2022, the 13-megawatt typhoon-resistant offshore wind turbine independently developed by China Dongfang Electric Group Co., Ltd. with completely independent intellectual property rights was successfully rolled off the line in Fujian Three Gorges Offshore Wind Power Industrial Park.

This is the wind turbine with the largest single-unit capacity and the largest impeller diameter in Asia that has been offline in China.

This 13-megawatt typhoon-resistant offshore wind turbine has a hub center height of 130 meters and an impeller diameter of 211 meters. It can generate 22.8 degrees of electricity in one rotation, and can meet the annual electricity consumption of 25,000 three-member families throughout the year. It will lead China's offshore wind power to achieve new breakthroughs and reach a new level, and create a new milestone of "great power".

"The 13 MW offshore wind turbines that have been rolled out this time are aimed at Class I wind regions such as Fujian and Guangdong, and are developed based on the 10 MW offshore direct drive platform that has been put into operation in batches and has mature technology. The rated power is increased by 30%, and the impeller diameter is increased from 185 mm The meter is increased to 211 meters, and under the average wind speed of 10 m/s, the usable hours exceed 4,100 hours. According to a project of 1 million kilowatts, compared with 10 MW units, the use of 13 MW wind turbines can reduce With 23 seats, the project cost can be saved by about 500 million yuan, which will effectively reduce the cost of electricity per kilowatt-hour, improve the return on investment of the owners, and effectively promote the realization of parity in offshore wind power.” Zheng Dazhou, deputy general manager of Dongfang Electric Wind Power Co., Ltd. introduced.Editor/Ma Xue
