The data shows that there are currently more than 80 complete wind turbine manufacturers in the country, and many companies are preparing to enter them. It is estimated that the production capacity of wind power equipment in China will exceed 20 million kilowatts in 2010, and the installed capacity of wind power is about 10 million kilowatts.
Judging from the current data, the production capacity of wind power equipment, especially wind turbines, in China does indeed show signs of surplus. However, from the perspective of development, the potential for the development of China's wind power industry is huge and the space is huge. The development prospects of wind power equipment, especially wind turbine manufacturing, may not be as pessimistic as people think.
With the rapid development of China's wind power industry in recent years, wind power equipment manufacturing industry has seen investment overheating and the phenomenon of a surge. The National Development and Reform Commission issued the “Several Opinions on Suppressing Overcapacity in Some Industries and Duplicate Construction to Guide the Healthy Development of Industries”.
To realize the healthy development of China's wind power equipment manufacturing industry, we must grasp two directions. First, it is necessary to increase the degree of independent innovation and make the company bigger and stronger and improve its market competitiveness. Second, it is necessary to increase the intensity of “going out”, actively participate in the international market competition, and expand the larger and broader space for survival and development.
In 2008, China’s total installed capacity of power generation has reached nearly 800 million kilowatts, while wind power has only 10 million kilowatts, which is less than 1%. By 2020, the installed capacity of wind power in China will reach 100 million kilowatts, and the total installed capacity of electric power will reach 1.5 billion kilowatts. The proportion of wind power in the entire power grid will reach 6%. By then, with the advancement of smart grids and energy storage technologies, nationwide power dispatch will gradually be realized, which will completely solve the practical problems such as low power load, large amount of wind power, and delivery difficulties in Northwest China, including Inner Mongolia and Gansu. The full purchase of wind power. That is, the potential of the wind power industry is huge.
Domestic wind turbine manufacturing companies can be divided into three "echelon". The output of Goldwind, Dalian Huarui, and Dongfang Steam Turbine in 2008 all reached more than 1 million kilowatts, which belongs to the first echelon; the output of Zhejiang Yunda, Shanghai Electric, Xiangdian, China Aerospace Wanyuan, etc. 250,000 kilowatts, belonging to the second echelon; another five companies have just begun small-scale production, the annual production of less than 100,000 kilowatts, can be classified as the third echelon.
"Going global" to participate in international market competition From the long-term perspective, China's wind power equipment manufacturing industry needs to tap domestic and international markets to digest production capacity. If it is said that improving the ability of independent innovation and promoting industrial upgrading is the basis for the revitalization of China's wind power equipment industry, then "going out" to participate in international market competition is the "path" of China's wind power equipment industry out of its difficulties.
First of all, standing on the analysis of global markets, the global wind power installed capacity has maintained an annual growth rate of 20% in the past 30 years. With the gradual release of new energy policies in various countries, the demand for wind turbines in the international market will be three to four times that of the domestic market. In particular, after the Copenhagen Climate Change Conference, renewable clean energy has become the world's energy development direction, and the most mature technology of wind power will become the first choice for developing renewable energy sources in various countries. It is expected that the global wind power industry will once again usher in a golden age of rapid development. For China's wind power equipment industry, this is undoubtedly an attractive cake.
Second, from the perspective of China's own advantages, China, as the world's factory, not only has cheap labor costs, but also has a relatively strong manufacturing base, and in the future, the international wind turbine manufacturing industry is shifting to China. For example, Vestas, the world’s largest wind power manufacturer, invested 3 billion yuan in China in 2009, and built production plants in Hohhot, Inner Mongolia, Tianjin, and Xuzhou, Jiangsu. In addition to their optimistic view of the Chinese market, they are even more The important purpose is to build an equipment base for the global wind power industry in China.
"Laowai" has come to our door to compete. How about our wind turbine manufacturing? Apart from actively developing ourselves and bravely participating in competition, we have no choice. In the context of economic globalization, Chinese companies must look globally to participate in competition. Although two major wind turbine manufacturers, including Dalian Huarui and Goldwind, have entered the top ten in the world, they are the giants of global heavy wind power equipment. Compared with Denmark, Vestas, US GE, Spain Gamesa, India Suzlon and other companies, the gap between our country is still quite large. The development of wind power equipment manufacturing companies in China is very difficult, but we must overcome difficulties and make our companies bigger and stronger.
Other companies are actually in prototype manufacturing or even just "idea" manufacturing stages. Therefore, more than 80 wind turbine manufacturers are only digital and cannot be equated with equipment production capacity. At present, the biggest problems in China's wind turbine manufacturing industry are the large number and small scale, and the lack of independent technology R&D strength, especially the small number of enterprises that truly have complete machine manufacturing capabilities.
Improving Independent Innovation Capability is the Key China Aerospace Wanyuan, as a holding subsidiary of China Academy of Launch Vehicle Technology, has independently developed a 600-kilowatt variable-pitch wind turbine technology since 1995, and successfully developed a WD646-type 600 KW with independent intellectual property rights. Pitch wind generators; In 2003, when megawatt wind turbines became the mainstream of wind power in the world today, China Aerospace quickly digested and mastered the megawatt-class wind turbine technology with the most advanced international level through international strategic cooperation; The AW1500 1500kW variable-speed constant-frequency wind generator jointly produced with the Spanish company went offline and was mass-produced in the same year. It was put into use in various wind farms in Zhangbei, Hebei, Rudong, Jiangsu and Cixi, Zhejiang, etc. The rate reached more than 98%.
Today, direct-drive wind turbines represent the development direction of wind power technology in the world. They have the advantages of high power generation efficiency, easy installation and maintenance, long unit life, small size, and low operating and maintenance costs. In 2007, China Space Rocket Institute introduced the 900kW direct drive wind turbine technology of Dutch EWT Company. Based on this, Aerospace Wanyuan has developed a 2MW permanent magnet direct-drive wind power generating unit with independent intellectual property rights. In 2008, the assembly plant and blade plant of China Aerospace Wanyuan Direct Drive Wind Turbine Co., Ltd. was built in Wulanchabu, Inner Mongolia. Currently, 110 sets of 900-kilowatt direct-drive blowers have been produced and small-scale production has been realized. It is estimated that by the first half of 2010, the 2 MW permanent-magnet direct-drive wind turbine developed independently by China Aerospace Wanyuan will be commissioned at the Xinghe Aerospace Wind Farm in Inner Mongolia. At the same time, pre-research work on 3 to 5 MW permanent-magnet direct-drive wind turbines suitable for offshore and beach power generation will also make a breakthrough.
The biggest obstacle to the healthy development of wind power equipment manufacturing industry in China is that the capacity for independent innovation research and development is weak. Many technologies need to rely on foreign R&D institutions to achieve this. It is embodied in the overall design and load calculation capacity of large wind turbines, and the poor design and production capacity of control systems, generators, gearboxes, and bearings. At the same time, China’s manufacturing industry base is still relatively weak, and parts such as bearings and control systems for wind turbines also need to be imported from abroad.
In the face of increasingly fierce market competition, China's wind power equipment manufacturing industry has realized that "adhering to independent innovation and research and development of high-end products" is the key to the survival and development of enterprises. In recent years, wind power equipment companies represented by Goldwind Technologies, China Aerospace Wanyuan, etc. have further increased their ability to independently innovate, and their core technology competitiveness has continued to increase.
