At present, although the proportion of wind power generating capacity is small, but the rapid growth of installed capacity, the initial realization of large-scale development. In 2008, in a variety of electricity generation method, only the country's total wind power generating capacity of 0.37%. In 2008 installed capacity of 6.14 million kilowatts new, and in 2007 an increase of 102%. China has basically mastered the 1.5-megawatt wind turbine manufacturing technology.
Â China's rapidly growing wind power industry to be the most important reason is the government support. Since 2005, the Chinese government incentives for wind power development policies and measures are: wind power equipment industry of special fund for subsidies, localization rate of 70% of the requirements, the full grid, electricity-sharing, wind power concessions and tax concessions to .
Â China Wind Power Industry Chain Market Analysis
Â In the wind power industry chain, wind power equipment manufacturing is the most important aspect of the upstream equipment manufacturers to provide raw materials for downstream use of equipment, power generation and electricity transmission to the user. The upstream industrial chain, including: steel, nonferrous metals, composites, electronic components and so on. Upstream and downstream industry chain to large state-owned power generation companies and energy investors, the main group.
Â Wind power equipment manufacturers, including wind power machine manufacturers and key components supporting businesses, the wind turbine is a wind power system, the most important part of the cost of wind farm construction investment accounting for about 70%. Present to achieve large-scale production units of the machine manufacturers are mainly Goldwind, Huarui wind power, Dongfang Steam Turbine. At the national policy support, the remarkable progress in wind turbine manufacturing.
Â Since 2003, the state has organized wind power concession tenders, wind power equipment manufacturing to "introduction of technology - digestion and absorption - independent research and development, technological upgrading - the scale of development, import substitution" development path to rapid development. Machine manufacturers to license the transfer, with the world wind power vendors to mature, the introduction of technology patents, to quickly form a machine manufacturing capacity, and this rapid introduction of technology, followed the path of China's equipment manufacturing industry tradition. As of the end of 2008, the domestic production of wind turbine within the capital and a total of 56 joint ventures, which produce megawatt class wind turbine technology, the main source of increase for the digestion and absorption of technology licensing, joint design and independent research and development. 1.5 MW wind turbine has been able to mass production, localization rate of more than 70%; unit capacity of up to 3 MW.
Â Independent research and development mainly MW units below the rank of supporting blades, generators, bearings, etc. have been able to mass production. At present, the domestic manufacturers to more than 50 blades, gear box manufacturers to more than 10, bearing more than 15 manufacturers, generator manufacturers to more than 15, variable flow of more than 10 manufacturers.
The help of national policy, local wind power companies have begun to emerge, a substantial increase in market share.
Â Wind power development in China, the first 20 years, wind farms use the equipment mostly imported products, equipment prices and maintenance repair costs are higher, ranging from a certain extent, this has hampered the development of wind power industry.
Â Countries to encourage the domestic wind power equipment manufacturing industry, clearly put forward the demand for equipment localization rate, domestic enterprises to occupy most of the additional market share. July 4, 2005, NDRC issued a notice to provide wind power equipment localization rate to reach over 70% of domestically produced equipment does not meet the requirements of the building of wind farms do not allow the import of equipment for the Customs to pay taxes. The new provision in 2006 requires operators of wind power equipment manufacturers with binding bids in order to ensure that the project truly achieve the localization rate of 70% of the requirements of operators in the successful tenderer after the tender shall be elected to conduct equipment manufacturers.
Â Golden wind, Huarui, East steam already have high-volume production capacity MW units in China, three companies and the market share of over 50%. As of the end of 2008, gold wind, Huarui, East gas enterprises amounted to 3 MW installed in the domestic unit Number of units a total of 2747 units.
Â To add a wind power installed capacity point of view, in 2008, first super-payment Huarui wind, in the new wind power installed capacity in the country accounting for 22.5%.
China's wind power industry, obstacles to development
Â However, the Chinese power grid planning and construction of the speed was nowhere near the speed of development of wind power installed capacity of large-scale wind power grid access barriers.
Â China wind power development in recent years, much faster than expected, a number of wind farm electricity can not be made to achieve a comprehensive transportation. In 2008, China has 12.21 million kilowatts of wind power installed capacity to achieve the grid, only 8.94 million kilowatts. Wind resources are relatively abundant in the west are mostly in remote mountainous areas, power transmission inconvenient.
Â Wind power will reduce the power load forecasting accuracy, thus affecting the power grid scheduling and stability. Foreign wind power development will be included in multi-network planning, demand ahead of construction of power grid for wind power to create conditions for access.
Â Wind power equipment manufacturing industry faster than strong, mainly influenced by level of technology and professional personnel constraints.
Â Domestic fan manufacturers are basically still at the stage of absorption of foreign technology transfer, has not yet formed its own core and key technologies, key components manufacturing and control systems are still controlled by others. China has produced just two megawatts of wind turbine capacity, large-scale wind turbine research and development of self-capability is weak. MW level and above the fan there is a big gap in the supply of core parts, and the local manufacturers is not enough and reliable product quality.
Â At present, the wind power industry, the lack of design, manufacture, installation, commissioning and operational management of the personnel training system, R & D and management personnel, the wind power industry service system is not perfect.
Wind power equipment manufacturing industry overcapacity
Â The rapid development of wind power industry, the huge market expectations, low market entry thresholds for wind power equipment manufacturing industry led to the explosive growth in the short term. As long as the wind power companies to buy production licenses and parts, will soon be able to produce products and a lower threshold. Wind power equipment manufacturers from 2004 to 2008, the development of six more than 70, only took 4 years.
Â It is estimated that over the next decade, China's average annual increase of installed capacity of about 800 million kilowatts. In addition to several leading enterprises, most enterprises only have a small batch production capacity, and some still in the prototype development or testing phase, the production of plant operation was not stable. More than 70 enterprises in the machine, there are 60 or so annual output of less than 10 units.
