China's first national offshore wind power research and testing base has recently started construction in Fujian, filling the gap that there is no high-power, full-scale ground test platform in China.
As a major project of the national "14th Five-Year Plan", the project is invested and constructed by State Grid, China Huadian Group and China Power Construction Group, and is scheduled to be completed and put into operation in 2024. After the completion of the base, it will further enhance the research and test verification capabilities of China's offshore wind power equipment, and help accelerate the breakthrough of key technologies and grid-connected technologies of offshore wind power equipment.
In recent years, the State Grid has continuously strengthened the research and test verification capacity of offshore wind power equipment. The offshore wind power test base is an important part of the National Key Laboratory of Renewable Energy Grid Integration, including two parts: onshore testing center and test wind farm, and its main function is to carry out full-scale ground tests of wind turbines with six degrees of freedom loading, ultra-large capacity complex power grid simulation, ultra-long blade biaxial high-frequency loading test and scientific research. The onshore testing center is located in Jiangyin Industrial Park, Fuqing City, Fujian ProvinceThe test wind farm plans to build 6 onshore test stands and 20-40 offshore test stands, and the first batch of 20 offshore test stands are located in the offshore area of Changle, Fujian Province.
The construction of offshore wind power test base is conducive to improving the level of scientific and technological innovation in China's wind power industry and seizing the commanding heights of world energy technology. With the rapid development of offshore wind power in China, offshore wind turbines have entered the era of large capacity. As of the end of September this year, the cumulative installed capacity of offshore wind power in China has reached 31.89 million kilowatts. Compared with the existing test and verification platforms at home and abroad, after the completion of the offshore wind power test base, it will form all the offshore wind power performance test and verification capabilities stipulated by the latest International Electrotechnical Commission (IEC) and relevant national standards, and the test platform has the first in the world in terms of drag capacity, loading capacity, power grid simulation ability and other technical indicators, which can carry out the world's largest capacity wind turbine and the longest size of the blade test and the full-frequency impedance scanning of offshore wind turbines that cannot be carried out in the world. After the completion of the offshore wind power test base, it integrates the functions of first-class analysis, operation testing, characteristic evaluation and technology research and development, and can carry out empirical research on large-capacity offshore wind turbine equipment, grid-friendly wind power grid-connected technology, offshore wind power single-station full-characteristic digital twin research and other international cutting-edge technology research, and lead the compilation of international standards, tackle key core technologies of offshore wind power, which will effectively enhance China's offshore wind power basic research and test capabilities.
The construction of offshore wind power test bases is conducive to the deep integration of the industrial chain innovation chain, promotes the upgrading of the offshore wind power industry, and drives the upgrading of the industrial base and the modernization of the industrial chain. After the completion of the base, it will further improve the innovation and service system of offshore wind power technology, provide a full range of services for the upstream and downstream of China's offshore wind power equipment manufacturing enterprises, scientific research institutions, operating units and other industrial chains, provide scientific research and research, test verification, exchange and sharing, promote the formation of a complete industrial ecology, accelerate product research and development and upgrading, improve the independent research and development capabilities and international competitiveness of China's electrical equipment manufacturing industry, and enhance the resilience and safety level of the industrial chain. The base will serve as a source of original technology, which will help accelerate the research and development of new technologies for wind power equipment, break through the bottleneck of large-capacity offshore wind turbines and large-size blade manufacturing technology, and improve the technical level of China's offshore wind power equipment manufacturing.
The construction of offshore wind power test bases is conducive to promoting the construction of new power systems and new energy systems, serving the clean and low-carbon transformation of energy, and helping to achieve the "dual carbon" goal. It is estimated that the theoretical reserves of offshore wind power in Fujian exceed 1200 million kilowatts, with the grid-connected operation of a number of large-capacity offshore wind turbines, the scale of offshore wind power grid-connected will continue to expand. The new power system has the characteristics of "double high" (high proportion of renewable energy and high proportion of power electronic equipment), and the requirements for the safe and stable operation of the power grid are constantly increasing. After the completion of the base, a grid-connected performance test and evaluation system for wind turbines based on ground tests will be formed, and relevant standards will be established to provide efficient and reliable technical means for the grid-connected test of large-capacity offshore wind turbines, improve the performance quality of wind turbines and the good level of grid connection, and provide guarantee for the safe and reliable operation of the power grid under large-scale wind power access.
