The Three Gorges Yangjiang Shaba offshore wind farm project is located in the South Sea area of Shaba Town, Yangxi County, Yangjiang City, Guangdong Province, with a planned total installed capacity of 1.7 million KW and a total investment of about 35 billion yuan. The project started construction in November 2018 and is divided into five phases, with a total of 269 offshore wind turbines installed
Li chuangjun, director of the new and renewable energy department of the National Energy Administration: the completion and operation of the project is of great significance to China's large-scale offshore wind farm construction, promoting the innovation and improvement of offshore wind power technology, promoting the clean and low-carbon transformation of energy in Guangdong, Hong Kong, Macao and the green and efficient development of marine economy.
It is understood that the project can provide about 4.7 billion kwh of clean electric energy for Guangdong, Hong Kong and Macao Dawan district every year, meet the annual power consumption of about 2 million households, save about 1.5 million tons of standard coal and reduce about 4 million tons of carbon dioxide every year.
Yangjiang wind power project not only has the world's first typhoon resistant floating offshore wind turbine, but also has created many "best in China", such as China's largest single offshore booster station and China's lightest offshore booster station with the same capacity.
China's offshore wind power installed capacity ranks first in the world
China has the natural advantage of developing offshore wind power, with an available sea area of more than 3 million square kilometers. The offshore wind power industry is developing from offshore to deep water and far shore. According to the latest data from the national energy administration, the installed scale of offshore wind power in China has ranked first in the world.
At present, China's mainstream offshore wind turbines are installed in offshore waters, mainly offshore projects with a water depth of less than 60 meters. Not long ago, the 800 MW offshore wind power project of state power investment Jiangsu Rudong, located in the Rudong sea area of Jiangsu Province with an offshore distance of 76 kilometers, realized full capacity grid connection. Coupled with the Three Gorges Yangjiang Shaba offshore wind farm, which realized full capacity grid connection power generation on the 25th, a number of energy central enterprises have begun to explore a new model for the development of offshore wind power.
The anti typhoon floating offshore wind turbine has been applied for the first time in Yangjiang Shaba offshore wind farm. Compared with the traditional wind turbine fixed on the offshore seabed, the floating turbine not only obtains the stable and high-quality wind power resources in the far-reaching sea area, but also does not affect the offshore fishery and other related industrial activities.
Qin Haiyan, Secretary General of the wind energy professional committee of China Renewable Energy Society: the floating (wind turbine) unit solves this problem. It doesn't need to be so deep. The fan floats there and can be transported to the site directly after the machine is installed.
At present, a series of key technologies of offshore wind power such as high-capacity offshore wind turbines, ultra long blades, floating wind turbines and long-distance power transmission projects locally developed and manufactured in China have made important breakthroughs. The technological innovation ability is in the first echelon in the world, and the core competitiveness advantage is obvious, laying a solid foundation for the large-scale development of offshore wind power in China in the future.
Li chuangjun, director of the new and renewable energy department of the National Energy Administration: China's offshore wind power has achieved a major breakthrough from small to large, from weak to strong, and from slow development to leapfrog development.
