Wind Power,Wind Turbine Manufacturer

Ningxia Electric Power Group and Japan’s Mitsubishi Heavy Industries Ltd. signed in Yinchuan City, 2.5 MW wind turbine technology supply contract. It is reported that the introduction of this technology marks the Ningxia will produce the world’s most advanced wind generator, and also shows the fan manufacturer Ningxia into the national advanced level, the development of equipment manufacturing industry in Ningxia and industrial restructuring will play a role in promoting more .

According to reports, in August 2006, Ningxia Electric Power Group and Mitsubishi Heavy Industries Ltd. of Japan signed the first letter of intent, thus pull the two sides co-production of wind turbines off; in May 2007, the two sides formally signed a 1 MW Fan technology supply contract. In 2008, the completion of plant construction and production system is prepared and produced five prototype hook run. The year 2009, production of a 100 MW fan, plans to produce 240 or more this year.

The contract was signed, both sides plan to produce 20 sets of 2.5 MW next year, fans. In accordance with Ningxia Electric Power Group, “12 Five Year Plan”, 2013, the fan capacity will reach 300.

To meet the large scale wind turbine needs the competition, the company the original 5-megawatt wind turbine development project changed to 6 MW wind turbine generator research project, and plans to be completed during the year, the preliminary machine design.
The progress of the project, the prototype design to be completed during the year. 2011, mainly debugging. 6 megawatts of wind generating units into market timing has not yet come. Foreign power overseas fans generally 5 MW wind projects gold rush of demand in the market before the technical level reached. This year and next year will not contribute to the company’s margins.
Goldwind large-capacity wind generators research and development has been going on now to achieve substantive results. R & D of 2.5 MW permanent magnet direct drive small wind turbine, 3.0 MW wind turbine hybrid drive 5 sets have been completed and a prototype installation, which owned subsidiary of the German Vensys EnergyAG completed a 2.5-megawatt permanent magnet direct drive wind turbine installation in Germany. The second half of 2010 units of 2.5 MW direct drive permanent magnet to achieve small batch production.
Goldwind securities on behalf of the tender is not that move offshore wind generator manufacturers, but the power company. But can not from the benefits of offshore wind power project, also see the power company and the company’s bundled wind turbine case.

To wind power development known Dabancheng wind zone, located in the Junggar Basin and Turpan basin vents with a total area of 1600 square kilometers, more than 10 months of the year the wind, the annual wind energy reserves of about 25 billion kwh can be installed capacity of more than 2000 MW, at home and abroad by many experts as the best conditions for wind energy resource in China, the development prospects of the region.
Bullish on wind energy reserves Dabancheng wind zone, the Danish Government in 1989 to donate three million U.S. dollars (403 million) of wind power generators equipment, construction in Xinjiang, China’s first wind power plant. Now, standing in Dabancheng wind zone stretches nearly 80 kilometers of 296 large wind turbines are being supplied with green electricity delivery to Urumqi, but also as a spectacular landscape of the southern suburbs of Urumqi.
Reporter last month to mid-called “China Wind Valley” Dabancheng wind zone, hair was not for a blown disorder, and at least one tenth of the wind turbine does not rotate.
Xinjiang Wind Power, general manager of Road-day peak of an interview, said: “Our line is dependent on the weather. Not too much wind, the wind is too small does not work, but the wind Dabancheng wind zone is the largest in Xinjiang, the most one of stability, generally the maximum wind generator in winter. we made the call directly into the city’s power grid in Xinjiang, accounting for a total capacity of nearly 2%. Xinjiang mainly by thermal power. ”
Xinjiang current price of wind power online than the average thermal power electricity price 0.25 yuan higher per kilowatt (RMB, same below about 0.05 dollars), the average price of 0.47 to 0.51 yuan, which run cost 0.30 yuan, more than the thermal power of about 0.10 yuan, while government subsidies average about 0.26 yuan.
Although Xinjiang is one of the earliest development of wind turbine, but did not significantly increase the proportion of new energy power generation in recent years the development has encountered bottlenecks, and coastal areas such as Inner Mongolia, Jilin, Liaoning and Heilongjiang to good.
Lu Feng pointed out that the main problem is supply and demand and cost, than the Chinese coastal city’s economic development in Xinjiang, many large power, a large market, and offshore wind power and lower transport costs. With a national focus on the development of the Xinjiang region, he believes that this trend may change.
According to Xinjiang’s long-term wind power development goals, the 2010 total installed capacity of wind power installed capacity in Xinjiang is expected to be the proportion of the total size of more than 5%, while Hamilton was incorporated into the national wind power plans, plans to build wind turbine generator 10 million kilowatts by 2020 wind power base .

2 MW wind turbines approved on September 7 shipped off the assembly line in East Taiwan, marking the wind power equipment manufacturing industry in our province formed a complete industrial chain.

Province rapid rise of wind power generators manufacturing, which had been able to mass leaves the control system, tower and other parts, but as a core component of the wind turbine has been imported. Dongtai introduced this year, the domestic wind power equipment manufacturer Shanghai Electric Group, the leader in a total investment of 2 billion yuan, mainly developing, producing 2 MW, 3.6 MW of power on land and sea fans. Project on February 2 this year, was started, only 120 days to successfully put into operation. In the first phase is completed, will form a 70-80 kilowatt wind generator production capacity, annual sales of 4 billion yuan.

Selsam invented a new type of multi-rotor wind turbine (wind generator) success came, the wind turbine rotor 25 (rotating device, wind vane) form, the power generated is 10 times that of ordinary steam, and can greatly lower manufacturing costs, especially for poor regions and developing countries to promote universal access.
The new wind turbines installed at a distance, like a snake dance in the air with the wind, inventor Doug – Selsam to the name “sky serpent.” However, this device in the air using wind turbine generaor electricity has not overlook. The world’s largest wind farm Kinderdijk Netherlands – elshout village, although only a small village, but most of the world’s largest wind turbine. However, in the inventor Doug – Selsam’s eyes, the use of turbine and equipped with the 747 wing-sized wind turbine is very clumsy and expensive. “Serpent sky” is very small leaves, and small footprint, and use of GE’s advanced rotary device (leaf) greatly increased the ability of the equipment acquisition. Selsam that the use of “sky serpent” wind turbines will increase the efficiency per unit of time and greatly reduce costs.
Selsam said, as early as 1000 years ago, humans began the use of wind, and designed the first wind collector. But over the years, the design and manufacture of wind turbines has been in the stage of a cost-inefficient. After his years of research, and Fluid Dynamics Laboratory at the University of California, with the help of the design in the early ’80s out of single-rotor wind turbines. But the years of actual use of the results further show that single-rotor turbine’s efficiency is very low, unable to raise the efficiency per unit of time, and because great covers an area of broad size, installation cost is very expensive. So since 1999, he was funded by the California Energy Commission, began to study multi-rotor wind turbines. In 2000, Selsam design and wind power generators manufacture the world’s first wind turbine rotor 7, and the application was successful. In 2003, he designed and manufactured to provide a 20-rotor 3000 watt wind turbine, a serious test after 20 rotor of this device was soon to be put into the market, and achieved considerable economic benefits. According to energy experts predict that this 20-rotor turbine efficiency increased by 40%, single-rotor turbine of the several dozen times.
Until recently, Selsam in the California General Electric Company turbine test facility has successfully tested his latest design and manufacture of wind turbine rotor 25 “sky serpent.” “The sky snake” is wind energy experts believe that is “crazy imagination,” which not only changed the traditional form of wind turbines and rotor, the number of records broken, the electricity generated is also very alarming. Selsam proud of that: this is only the beginning, will snake across the sky, flying in the sky. It is reported that “the sky snake” cost 25 million U.S. dollars, life is 9 years, the United States than the world famous GE’s small wind turbines confidential stronger and more competitive.

Recently, China’s wind power generators industry, supporting the largest wind turbine manufacturer – China North Vehicle Yongji Electric wind power company and the host country has signed a total power of 4.5 million kilowatts, the contract amount of 1.155 billion yuan to 1.5 MW doubly-fed water wind turbine contract, become the largest water-cooled two-fed a megawatt-class wind turbines, so that enterprises continue to mainstream models in the megawatt-class playing the role of national leader.
It is understood that the user-developed water-cooled 1.5 MW doubly-fed wind generator, upgrading the company’s products, through further optimization of the design, each reduction in the weight of 400 kilograms, the contract will be completed in late 2011 delivery . MW of wind power to motor assembly, the company started construction in April this year, megawatt-class wind power motor assembly plant, permanent plant project, to meet the company the next 3-5 years to expand wind power market needs.
Yongji motor to green clean energy as a strategic objective of sustainable development companies, new product research and development of wind power turbines has not only been the state policy and funding on the great support, but also has included in the State Economic and Trade Commission in 2002 Technical Innovation Project, Ministry of Science, “10 5 “research projects, take the” Eleventh Five-Year “National Science and Technology Support Programme” adapt to the complex conditions of high-power wind turbine industrialization “, in May 2009, the company was included in the Shanxi provincial government 2009-2011″ equipment manufacturing restructuring and revitalization plan “in the new energy equipment wind generator manufacturing base. The company set up wind power product quality enhancement projects set, new technology, new methods of capturing wind power key Bujian the rotor assembly Zhou put Chaochai  problem and developed through exploration Yizheng Tao Yun Hang  of technical data, reduce Zhiliang loss of 600 million yuan. Wind on the staff to enhance the quality of wire wrapped ring, the product appearance of quality standards, the motor assembly cleaning job training, the overall improve products quality.

As the land of wind resources in the economy can be developed less and less, the global wind power generator development has emerged from the land to the offshore trend, compared with land-based wind power, wind energy resources offshore wind energy wind farm on land higher than benefits 20% -40%. According to statistics, over the past 2009 years, the global offshore wind generators showed explosive growth, the global installed capacity of offshore wind power new 689MW, up 100%, far higher than the 30.1% growth rate of land-based wind power.
In this context, since China’s east coast and Europe, the United Kingdom, Denmark, wind power development Xunsu Haishang the country’s geography and natural Tiaojianbijiao similarity, developed economy, Dianwangrongliang Da, Dan Chang Gui energy shortage, Yi Ci energy Zhuyaoyilai provinces Shuru or imports, China has formulated the future development of offshore wind power the basic idea. The future will mainly rely on the “Three North”, the eastern coastal and offshore wind energy resource rich region, according to “Building a large base and integrate into the bulk power system” means large-scale development planning and construction of wind farms, offshore wind power development is bound to form a new round of boom.
This is true. In recent years, the National Energy Bureau of China’s coastal areas to speed up large-scale wind power bases, launched at sea level in coastal areas and 10 million kilowatts of wind power base in the intertidal zone construction planning, and began construction of several offshore wind farm early stage preparation. This year in June, China’s first offshore wind power concession bidding started, attracted a lot of wind power giant bidding.
Wave surge, the development prospects of offshore wind power related equipment also means a huge market demand. Currently, 3MW-5MW offshore wind turbine unit is the mainstream, and its main providers of Vestas Corporation, Siemens Corporation, GE company, REpower companies and Sinovel China, all of these companies every year hundreds of megawatts of capacity only, The market prospect is very impressive.

Net Control of wind generator can directly affect the transmission power to the grid and the grid when the units are subject to the impact of current.

And network control software and network installations, operation and rectifier buck inverter in three ways.

Soft and network devices:

Induction generator directly to the grid, the impact current to rated current of 6 to 8 times, in order to reduce the direct impact generated when the grid current and contactor switching frequency, wind speed in wind speed consistently lower than the start after some time Wind power only and power splitting, during which wind turbines in the motor running, absorb active power from the grid.

Buck running gear:

Soft and network devices in the wind turbine generator only starts to run, and step-down operation unit has run, control methods are more complicated. The small wind turbines installed in wind speed less than the start wind speed and wind turbines will cut off power to avoid the home wind generator motor running.

Rectifier inverter device:

Rectifier reverse is a better way grid, it can control the reactive power is conducive to the safe operation of power systems, disadvantage is high cost. With the expanded scale wind power and power electronic equipment at lower prices, the future of this and the network device may be widely used.

Wind Power System program mainly by the wind farm installed capacity of wind electric field in the final grid position to determine.

Recently, the Chongqing municipal government announced two strategic planning in the New River, which wind power generators equipment to become the second largest strategic industries. Related departments plan to integrate wind power generator system, based on focus on developing key components and supporting components manufacturing, while China Shipbuilding Heavy Industry (Chongqing) Sea Wind Power Equipment Co., Ltd. will install two rivers in Chongqing New wind generators industry play a more important role.
Chongqing wind power equipment company Shanghai has assumed “national offshore wind turbine generator engineering technology research center” of this task, the same time, as a “wind Chongqing Engineering Research Center,” New River in two core industry, the second largest development strategies play a pivotal effect.
Mu Qian, the company as major projects in Chongqing, Yi pair of local 风 chain driven power industry has played a positive role in end of this year, will form a two million kilowatts of wind power equipment and supporting Ling Bujian production capacity to 20 billion yuan of industrial Dai Dong Chain Sales. 2015, Chongqing wind power equipment industry will complete the 20 billion yuan investment, the formation of two million kilowatts of wind power terrestrial and marine wind power capacity and improve the wind turbines supporting system components, output value of 40 billion yuan into the domestic TV industry cluster of wind power .

Evaporative cooling power of wind power generator equipment R & D center and production base project settled in Qingdao High-tech Zone, the project by the China Academy of Engineering Experiment on Two academicians led research and development, with generator independent intellectual property rights and to fill the gap.

The wind turbines is reported that the total investment 560 million yuan, is expected to put into production the end of 2011. A production, you can form an annual production capacity of 1,000 sets of equipment, production value more than 2 billion yuan.
