China wind power equipment development outlook

With the rapid development of China's wind power industry in recent years, investment in wind power equipment manufacturing industry has seen overheated investments and a phenomenon that has occurred overnight. Where is the wind power equipment in China?

Some experts believe that in terms of long-term development, 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 capability of independent innovation and promoting industrial upgrading is the basis for the revitalization of China's wind power equipment industry, then “going global” to participate in international market competition is a “path” for China's wind power equipment industry to get out of the difficulties.

At present, domestic wind turbine manufacturing enterprises have gradually formed large-scale wind power enterprises with complete machine production capabilities such as Goldwind Technologies, Guodian United Power, Huarui Wind Power, Dongfang Steam Turbine, Zhejiang Yunda, Shanghai Electric and Xiangdian. These companies are in the leading position both in the production of the whole machine and the production of parts and components.

Improve the ability of independent innovation is the key

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 researching and developing 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.

China Aerospace Wanyuan, as a holding subsidiary of the China Academy of Launch Vehicle Technology, has independently developed a 600-kilometer pitch variable wind turbine technology since 1995, and successfully developed a WD646 600KW variable-pitch wind turbine with independent intellectual property rights; 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; in 2006, it invested in production with Spanish companies. The AW1500 1500-kw variable speed constant-frequency wind generators went offline and achieved mass production that year. They were put into use in various wind farms in Zhangbei, Hebei, Rudong, Jiangsu, and Cixi, Zhejiang, respectively. The availability rate was over 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, ease of installation and maintenance, long unit life, small size, and low life-cycle operation 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. At present, 110 sets of 900-kilowatt direct-drive blowers have been produced, and small batch production has been realized. It is estimated that by the first half of 2010, the 2 MW permanent-magnet direct-drive wind turbine independently developed 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 tidal flat power generation will also make a breakthrough.

"Going out" to participate in international market competition

In terms of long-term development, 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 capability of independent innovation and promoting industrial upgrading is the basis for the revitalization of China's wind power equipment industry, then “going global” to participate in international market competition is a “path” for China's wind power equipment industry to get out of the 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 the international wind turbine manufacturing industry is shifting to China in the future. 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 respectively. Apart from being optimistic about 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, such as Dalian Huarui and Goldwind, have entered the top ten in the world, they are the giants of global heavy wind power equipment. The gap between China's Vestas, U.S. GE, Spain's Gamesa, and India's Suzlon is still quite large. The development of China's wind power equipment manufacturing companies is very difficult, but we must overcome difficulties and make our companies bigger and stronger.
