In order to further implement the National Medium - and Long Term Science and Technology Development Plan (2006-2020) and the National Twelfth Five Year Plan for Science and Technology Development, accelerate the innovation and development of the energy technology industry, on March 27, 2012, the Ministry of Science and Technology of the People's Republic of China issued the "Twelfth Five Year Plan for the Development of Wind Power Technology" with the document of National Science and Technology Development Plan [2012] No. 197. The Plan is divided into six parts: current situation, situation and needs, overall ideas, key directions, key tasks, and guarantee measures.

1、 Current situation

During the 11th Five Year Plan period, China's wind power industry has attracted attention and has become a leader in new energy, with a certain international influence. With the strong support of the country and the joint efforts of scientific research institutions, wind power enterprises, and other parties, China has established a certain foundation in wind energy resource assessment, design and manufacturing of wind turbine units and components, testing and certification, wind farm development and operation, and wind farm grid connection, and has initially formed a complete wind power industry chain. In the field of offshore wind power development, key technologies such as offshore transportation, installation, and construction have been preliminarily solved, and experience in operating offshore wind farms has been accumulated. In terms of talent cultivation, a certain scale of wind power professional talent team has been initially formed, and the construction of the wind power discipline has also begun.

（1） Industrialization of wind power equipment

Under the guidance of the 11th Five Year Plan for Science and Technology, domestic research institutions and enterprises have mastered the industrialization technology of 1.5MW to 3.0MW wind turbines through digestion and absorption of imported technology, commissioned design, joint design with foreign countries, and independent research and development. At present, domestically produced 1.5MW to 2.0MW wind turbines are the mainstream models in the domestic market, with a small number exported; 2.5MW and 3.0MW wind turbines have been applied in small batches; 3.6MW and 5.0MW wind turbines already have prototypes; Wind turbines with larger capacities such as 6.0MW are being developed. The manufacturing capacity of domestic components such as blades, gearboxes, and generators has approached the international advanced level, meeting the supporting needs of mainstream models and starting to export; Significant progress has been made in the research and development of bearings, inverters, and control systems, which are now being supplied to the domestic market.

As of the end of 2010, there were over 20 enterprises in China with mass production capacity for megawatt level wind turbines. In 2010, the top five wind turbine manufacturers with new installed capacity accounted for over 70% of the national market share. Four enterprises in China entered the top ten globally in terms of newly installed capacity in 2010.

（2） Construction and resource development of wind farms

The implementation of the Renewable Energy Law of the People's Republic of China and a series of supporting policies has promoted the rapid growth of domestic wind power development. In 2010, China's wind power added 18.9 million kilowatts of installed capacity, ranking first in the world. As of the end of 2010, there were over 20 developers in China with the ability to build large-scale wind farms, with a total of over 800 wind farms built. The total installed capacity of wind power (excluding Taiwan Province) was 44.7 million kilowatts, surpassing the United States and ranking first in the world.

During the 11th Five Year Plan period, China has initiated offshore wind power development. The first offshore project, the Shanghai Donghai Bridge Wind Farm, installed 34 domestically produced 3.0MW wind turbines and achieved grid connected power generation in June 2010; In September 2010, the National Energy Administration organized and completed the first round of bidding for offshore wind power concession projects, with a total capacity of 1 million kilowatts, located in the coastal and intertidal areas of Jiangsu Province.

（3） Development of Wind Power Science and Technology and Public Services

During the 11th Five Year Plan period, China has achieved a number of achievements with independent intellectual property rights in the field of wind power key science and technology, such as the design of large wind turbines and key components, blade and airfoil design, breaking the monopoly of foreign countries on wind power science and technology. In the field of offshore wind power development, China has independently researched and developed a series of offshore wind farm design and construction technologies, and developed a batch of specialized offshore wind power construction machinery and equipment.

The rapid development of the wind power industry has also promoted the construction of the public service system in the wind power industry. During the "Eleventh Five Year Plan" period, China has established a number of State Key Laboratory and national engineering technology research centers related to wind energy, and preliminarily established wind power standards, testing and certification systems with reference to international practices, providing technical support and guarantee for China's wind power development.

（4） Situation of Wind Power Talent Team and Discipline Construction

During the 11th Five Year Plan period, the development of China's wind power industry has promoted the construction of wind power talent teams and disciplines. At present, China has a group of professional talents in various fields of the wind power industry, such as wind resource survey and analysis, design and manufacturing of wind turbine units and components, wind farm design, construction and operation maintenance, and wind power grid connection, forming a skilled technical team for the entire wind power industry chain and attracting a large number of excellent foreign wind power talents to join. In terms of disciplinary construction, China has initially established the Wind Energy and Power Engineering major and started to cultivate specialized talents.

2、 Situation and demand

（1） The current situation

Through years of continuous support from the country, China has made significant progress in the field of wind power technology, but there is still a significant gap compared to the international advanced level. Based on the current situation and domestic and international trends of China's wind power industry, China still faces a series of challenges in the field of wind power technology, mainly manifested in:

1. The independent design and innovation capabilities of advanced wind power equipment need to be strengthened.

In the early days, China's wind turbines mainly relied on the introduction of foreign design technology or joint design with foreign institutions. The ability to independently design and develop new wind turbines based on China's wind resources and other environmental conditions was insufficient, and there was a lack of wind turbine design tool software systems with independent intellectual property rights.

In terms of wind power components, China has weak independent innovation capabilities, and the intelligent processing and quality control technology in the manufacturing process is relatively backward. The reliability of gearboxes and generators needs to be improved; The blades are in the early stage of independent design; The bearings and inverters for wind turbines above megawatt level have just begun small-scale production, and the control system is still in the demonstration application stage.

2. The basic data on wind resources is incomplete, and key technologies such as wind farm design, grid connection, and operation need to be improved.

The evaluation of available wind energy resources in China is not yet precise, and the long-term wind resource data required for wind farm design is incomplete; Wind farm design tools rely on foreign software products and lack independent intellectual property rights, wind resource assessment, and wind farm design and optimization software systems that meet China's environmental and terrain conditions; The technology of wind power grid connection urgently needs in-depth research and innovation to improve the level of wind power grid connection consumption; We have not yet formed an independently developed advanced operation control and wind power prediction system for wind farm operation and optimization.

3. The public testing system for the wind power industry has just begun, and the wind power standards, testing, and certification system need to be further improved.

China has initially established wind power standards, testing, and certification systems based on international practices. However, considering the special environmental conditions (such as typhoons, low temperatures, high altitudes, etc.) and the differences in industrial foundation between China and the international community, further improvement is needed according to China's national conditions. The testing and related testing system design of China's wind power industry mainly rely on foreign countries, which restricts the development of China's wind power technology. However, developed countries in Europe and America have established a complete public testing service system for national level wind turbine field testing, ground transmission chain and blade testing, making contributions to the development of China's wind power industry.

4. The basic theoretical research on wind power still needs to be deepened, and there is a lack of independent innovation; The construction of wind power discipline and talent cultivation urgently need to be strengthened.

Due to the late large-scale development of wind power, China has insufficient accumulation in basic theoretical research on wind power. Most of the research results are directly referenced or tracked from foreign countries, resulting in insufficient technological breakthroughs and innovation capabilities. There is a significant gap between the research level of wind power and that of foreign countries, and the systematic training mechanism for wind power researchers needs to be strengthened.

5. Further improvement is needed in the research and development of small and medium-sized wind turbines and non grid connected wind power access technologies.

China's production and usage of small wind turbines rank first in the world, but the performance and reliability of the products need to be improved. The research and development of medium-sized wind turbines and distributed access technology for wind power non grid connection have just begun, and continuous research and demonstration are needed in wind power microgrid technology and multi energy complementary utilization integration technology.

6. The research on direct industrial application technology of wind power needs to be expanded.

Although the installed capacity of wind power in China is rapidly increasing, technological research on how to use large-scale energy storage to reduce the uncertainty of wind power, as well as how to use wind energy for industrial direct applications such as hydrogen production and seawater desalination, has just begun and needs further expansion.

（2）Strategic requirements

In the next five years, China's wind power generation technology will gradually achieve a transformation from quantity to quality, improve and develop the strength of wind power generation technology, and achieve the transformation from a wind power powerhouse to a wind power powerhouse.

According to the 12th Five Year Plan for National Economic and Social Development released by China, during the 12th Five Year Plan period, China plans to add more than 70 million kilowatts of wind power. From the perspective of China's energy planning, carbon reduction targets, and industrial development needs, the strategic needs of wind power generation technology in China are mainly reflected in:

1. The need for the construction of super large wind farms

The construction of super large wind farms is a key demand for wind power development in China, and foreign countries cannot provide direct experience. During the 12th Five Year Plan period, the country plans to build 6 onshore and 2 offshore and coastal wind power bases. There is an urgent need for scientific and technological development and innovation in the assessment of wind resources, design of wind farms, grid connected consumption and intelligent operation management, as well as large capacity, high reliability, high efficiency, and low-cost wind turbines, in order to provide technical support for the construction of China's mega wind farms.

2. The need for large-scale offshore wind power development

China's offshore wind power has already started, and during the 12th Five Year Plan period, intertidal and offshore wind power will enter a stage of rapid development and large-scale development. Therefore, it is necessary to carry out research on key technologies for the development and industrialization of offshore wind turbines, strengthen research on key technologies for offshore (intertidal) wind farm development such as engineering construction and grid connection, and provide technical support for large-scale offshore wind power development.

3. The need for independent innovation system, capacity building, and talent cultivation in wind power

During the 12th Five Year Plan period, in conjunction with the overall deployment of the national energy industry and wind power technology development strategy, there is an urgent need to establish a public research and development testing service system, develop wind power design tool software systems with independent intellectual property rights based on China's environmental and terrain conditions, achieve technological breakthroughs in the integration of whole machine design and key component manufacturing, and achieve the joint development of production, learning, research, and application. This will provide conditions and support for the performance optimization and independent design of China's wind power equipment, and ensure the sustained, rapid, and stable growth of China's wind power industry.
