The hottest wind power during the 12th Five Year P

The 12th Five Year Plan for wind power: the 12th Five Year Plan for national energy science and technology, a programmatic document for China's energy development, was officially announced a few days ago. The trend of large-scale fans has been described in heavy colors. The plan has made clearer requirements for fan power, parts, and R & D platform. China's plastic sealing machine has made considerable development requirements

insiders believe that at present, the profits of domestic wind power enterprises' traditional 1.5 MW wind turbines are declining year by year, and there is an urgent need to explore new profit growth points. Large-scale wind turbines have become a new market they are striving to explore. At this time, the plan encourages wind turbine enterprises to innovate and develop in the field of large-scale wind turbines, which is a good incentive for wind power enterprises and will promote them to speed up the research, development and application in the field of large-scale wind turbines. Under the joint action of internal and external forces, it can be predicted that the large-scale wind turbine will become a major trend of industry development and a new battlefield of competition during the "12th Five Year Plan"

internal cause: enterprises actively explore the blue ocean

after maintaining high-speed growth for several consecutive years, the performance of the domestic wind power industry began to show signs of correction in 2011

according to the 2011 performance express recently released by Goldwind technology, its operating revenue in 2011 was 12.871 billion yuan, a year-on-year decrease of 26.85%; The operating profit was 698 million yuan, a year-on-year decrease of 74.06%. Sinovel's performance expectations also fell by half

not only the manufacturers of complete fans encountered difficulties, but also the enterprises such as blades, towers and gearboxes failed to escape the fate of reduced gross profit and declining profits

Sinoma's 2011 performance express showed that its operating revenue and total profit decreased by 76.00% and 57.92% year-on-year, respectively, because "affected by the market, the sales price of leaves decreased"

the industry generally believes that the current decline in the performance of wind turbine enterprises is caused by many reasons. The rise of raw materials, overcapacity, fierce price war, market contraction and many other factors have led to a plunge in enterprise performance

at the 2012 national energy work conference held at the beginning of this year, Liu Tienan, deputy director of the national development and Reform Commission and director of the national energy administration, reported the main data of wind power development in 2011: the combined capacity of wind power increased by 16million kW (16 GW), reaching a total of 47million kW (47 GW). Previously, the national development and Reform Commission said that the installed capacity target of China's wind power in 2015 was initially set at 100million kW (100 GW)

in this regard, insiders said that this means that the average annual installed capacity will fall back to around 15 gigawatts, lower than the previous new installed capacity rate

compared with the expectation of lowering the installed capacity, the capacity of domestic wind power enterprises is still running at a high level

continue to struggle in the red sea of traditional low-power models, or explore new blue oceans to find new profit growth points? Some wind power giants with technology and strength have made choices, and high-power models have become their targets

Tao Gang, senior vice president of Sinovel wind power, said, "in the face of fierce market competition, Sinovel wind power has taken a variety of measures to reduce production costs, focusing on the development of large-scale wind turbines of 3 MW and above, and maintaining and expanding its domestic market share."

"the trend of high-power wind turbine is the result of technological progress." Tao Gang said that from the perspective of the development trend of the global wind power equipment industry, high-quality and high-power wind turbines are increasingly favored by the market

it is reported that 34 3-megawatt offshore wind turbines independently developed by Sinovel wind power have been fully combined and generated electricity in China's first national offshore wind power demonstration project - Shanghai Donghai Bridge Wind Farm phase I project. As of March 1, 2012, the cumulative power generation of this project has exceeded 371million kwh. In addition, the intertidal 3 MW wind turbine independently developed by the company has also been successfully put into operation in Jiangsu Rudong intertidal wind farm

external cause: the national support policy promotes

in the recently announced 12th Five Year Plan for national energy science and technology, the requirements for large-scale wind turbines are highlighted, and the industry management departments try to use administrative power to promote the large-scale development of wind power. According to the mutual pollution plan, the complete machine manufacturing technology of 6-10 MW land (Offshore) variable speed constant frequency wind turbines (double fed and direct drive) with independent intellectual property rights will be developed in the next five years

in fact, at this stage, the commercial application of 6 MW wind turbines in the field of offshore wind power worldwide is still in the blue ocean stage, and there are not many participants. Chinese enterprises have been involved in it for the first time

it is reported that Vestas, the world's No. 1 wind power equipment manufacturer in the wind power industry, announced that it would provide 15 6-megawatt offshore wind turbines for PNE, a German wind farm developer, in the German North Sea; REpower, a veteran German wind power giant, is expected to complete the installation of 6 MW offshore wind turbines at nordsee OST wind farm in the North Sea of Germany in 2013

in this field, domestic first-line wind power leading enterprises are not lagging behind. Sinovel wind power, China's first and world's second wind power equipment manufacturer, has successfully developed sl6000 Series 6 MW large-scale offshore wind turbines, and won the bid for Shanghai Lingang offshore wind power phase I demonstration project at the end of 2011. The 6 MW unit of Guodian united power was also offline in Lianyungang base at the beginning of this year

it is understood that with the consent of the national energy administration and the Shanghai municipal government, through the bidding of the owners of the Shanghai Lingang offshore wind power phase I demonstration project, it has been confirmed that the consortium of Huaneng new energy Co., Ltd., Shanghai Shenneng New Energy Investment Co., Ltd. and Shanghai green environmental Energy Co., Ltd. has won the bid in a "bundle" with Sinovel, the wind power manufacturer with the largest single unit capacity in Asia. This will be the first large-scale commercial use of 6 MW offshore wind turbines in the world, and it is also another new milestone in the development of offshore wind power after Sinovel won the bid for the 100000 kW project of Shanghai Donghai Bridge, China's first national offshore wind power demonstration project

in addition to the requirements for the whole machine, the plan also puts forward requirements for the key technologies of large-scale onshore and offshore wind power generation. Including the key control technologies of large-scale onshore and offshore wind turbines; Airfoil design and blade optimization design technology; Design technology of high-power gear box with medium and high speed ratio; Large scale wind turbine design and optimization technology; Detection technology of large-scale wind turbine and key components; Load analysis and anti fatigue design technology; Coping technology of large-scale wind turbine under extreme conditions (typhoon, strong wind and sand, low temperature, corrosion, etc.); Adaptive control technology of large wind turbine

domestic wind power enterprises have also made adequate preparations in this field

it is reported that Sinovel wind power sl6000 series wind turbine is currently China's first 6 MW power friendly wind turbine with independent research and development, complete independent intellectual property rights and global technology leadership. The low voltage ride through capability of sl6000 enables it to meet the stringent requirements of current conductivity rules, and its special anti-corrosion system meets the high salt fog and high corrosion operating environment at sea. This has basically completed the requirements for specific technical fields of large-scale fans in the 12th Five Year Plan of national energy science and technology

in addition, the 12th Five Year Plan for national energy science and technology also puts forward the requirements for the construction of wind power technology and equipment research and development platform, solves the key technical problems of super large wind turbines, forms the manufacturing capacity of key components of large wind turbines, and becomes an influential international cooperative scientific research platform and wind power technology research base in the field of wind power technology research and manufacturing
