Wind Turbines Manufacturer in China

Vaal University of Technology Innovation Center Director, Professor Jan Yost has recently invented a new type of structure, the vertical axis wind turbines. Yost said that the invention will greatly reduce the cost of wind power, the horizontal axis wind turbines will be gradually replaced by the vertical axis wind turbines.
At present a common wind turbine , which leaves in the wind-driven rotating around the horizontal axis; while the wind generators , the name suggests, it leaves the vertical setting, which leaves around a similar vertical shaft rotation.
Yost said that in general the wind turbine generator contains only a layer of leaves is different from his invention of the vertical axis wind turbine by interlocking the upper, middle and lower leaves composed of three vertical. As two more blades, the interception of wind energy area increased by 200%, while the fan wind power generation capacity and cut-off proportional to the area.
Meanwhile, the general wind turbine is different from his new design the plant to continue to rotate in strong wind, you can intercept more energy, this power-generating capacity will increase 200%.
According to theoretical calculations, this new structure will make it generate electricity generator power vertical axis wind turbines than the average increase 400%. The preliminary results of wind tunnel tests also support this reasoning.
Yost said that in comparison with the horizontal axis wind turbines, vertical axis turbine blades of the material is not demanding and easier to manufacture, and easy to implement automated production.
At present, the equipment manufacturing, installation and other early stage investment accounted for 70% of the cost of wind power, if the initial investment reduced by 60% of the cost of wind power will decrease by 42%. In this way, even if no policy subsidies, wind power generation would also be a wise choice.
Yost said that they would within two years, so that 100-kilowatt vertical-axis wind turbine works, and a MW within 5 years to complete the development of vertical axis wind turbines.

According to statistics released by EWEA, the European retired in 2009 coal-fired and nuclear power capacity greater than the ability to set. Renewable energy technologies together account for 2009 new generating capacity to 61%.
2009 European new wind farm investment reached 13 billion euros, including 1.5 billion euros at sea. Throughout the EU in 2009 set up wind generators capacity of 10,163 MW, compared with 2008 growth of 23%. Among them, land-based wind power generation capacity of 9,581 MW (an increase of 21%), offshore wind power generation capacity of 582 MW (an increase of 56%).
2009 is a new wind power capacity than any other generation technologies, the second year. Wind power accounts for the share of new generating capacity to 35% from 2008 to 2009 accounted for 39%. 2009 is also a renewable energy accounted for a larger share of total new investment in the second year.
New wind capacity in 2009 set up accounts for wind turbines the largest share of new electricity generating capacity of countries: Spain (24% – 2459 MW), followed by Germany (19% – 1917 MW), Italy (11% – 1114 MW), France (11 % – 1088 MW) and the United Kingdom (10% – 1077 MW).
EU’s total wind power capacity to 64,719 MW from the end of 2008 to 2009, 74,767 MW, the German EU countries remain the largest capacity of wind power is set, followed by Spain, Italy, France and Britain. As of 2009, set up wind power capacity to produce 163 TWh, accounting for EU’s total electricity demand of 4.8%.

Wind power industry in the coastal special promotion conference, a 1,000-kilowatt-class county, Jiangsu Province, the largest wind power development plan for the successful launch.

Dafeng, Jiangsu Province, coastal development is an important node in one of the delegates that the Dafeng Port Phase II Project to speed up construction will  wind turbines promote the energy, petrochemicals, wood and agricultural products deep processing, metallurgical machinery, bio-pharmaceutical industry development characteristics of five major port . According to “Wind generator in Jiangsu Province Development Plan (2006-2020)”, wind generators Dafeng in the construction of six million kilowatts over offshore wind farms, accounting for the province’s total installed capacity of wind power planning 1 / 4, which marks the largest in Jiangsu wind generators Province county-level planning to start offshore wind power.

The two five-year study by the American Academy of Pediatrics Fellow, New York pediatrician, Dr. Nina Pi Niwa point over the completion of research concerns the United States, Britain, Italy, Ireland and Canada, five countries living in the vicinity of the wind power station of 38 residents .

Dr. Pierpoint, wind turbines would interfere with low-frequency sounds given ear vestibular balance system.

The noise frequency is very low, the human ear can not hear, but it will lead to “visceral vibration-induced vestibular disturbance” (VVVD). Symptoms include trembling, nervousness, fear, escape impulse, such as chest tightness, and tachycardia. Wind turbines may also trigger nightmares of children and prevent children’s normal development of the brain, leading to cognitive developmental disorders.

For a long time, voice scientists believe that if people can not hear a sound, then the other parts of the body can not discern such a low frequency sound.

However, Dr. Pierpoint, people can in fact be by skeleton “listening” sound; Not everyone living in the vicinity of the wind power station people will be hurt, but the future of wind power stations should be built at a distance of 2 km away from residential areas.

wind turbines has brought clean energy to people, but the U.S. National Research Council released a report on the 3rd that a huge wind farm non-stop paddle rotation is likely to endanger the survival of birds, the songbirds, bats and other nocturnal animals may greater threat.
Reported that the wind power generation in some areas may have adverse ecological effects, such as birds and bats lead to death. But scientists need to spend more time to study, it is not possible to make a final conclusion of this threat.
The study found that in Virginia, West Virginia, Maryland and Pennsylvania that use wind generators areas, bat the number of deaths is higher than other regions.
The report also pointed out that under the present circumstances, wind power did not lead to the total decline in the nation’s birds.
In addition, too much wind power plant may also produce electromagnetic effects, interference to local television and radio signals, affect the use of mobile phones and so on.
National Research Council noted that the United States in 2006 wind power is 11605 MW, less than 1% of the national total, but in the next 15 years, this ratio will rise to 7%.

Base in the Northeast will be Baicheng, Liaoning Fuxin focus; Hebei Zhangjiakou, Chengde; Jiuquan, Gansu Province; southeast of Hami, Xinjiang; Jiangsu Nantong, Yancheng and Lianyungang [7.16-0.28%] and so are the core development areas of wind power.

The amount of wind power installed capacity planning is the biggest in Inner Mongolia: 2020 target of 28 million kilowatts, Baotou Ta-mao, Ulanqab auspicious, Xilinguole gray Teng Liang, and Chifeng and Tongliao are the main areas.

Although the draft does not open, but some parts of the wind power planning has confirmed the reliability of the draft. Zhangjiakou Municipal Development and Reform Commission, an official told our reporter, Hebei Province, in 2020 there should be 10 million kilowatts of  wind generators installed capacity.

However, the Bill to the figures seem to be somewhat conservative. As Bill mentions that “in 2011 in Hebei Province, four million kilowatts of wind power installed capacity”, in Zhangjiakou who officials seem somewhat underestimated, “Zhangjiakou in 2009 have built two million kilowatts, and 2010 may be 5 million kilowatts . ”

Gansu Province in 2015 wind power planning is more than 1200 MW, but the draft to “the amount of the total installed capacity of Gansu in 2020 provides a” 13 million kilowatts, “five years grew by only 1 million kilowatts is also somewhat conservative.

China Merchants Securities researcher Wang Sheng pointed out that, in fact, the domestic wind power developed rapidly, the state’s plan may be modified, “This may also be the new energy plan has not been introduced in the revitalization of the reasons for it.”

In 2008 China’s total installed wind power capacity has reached 12.21 million kilowatts, has completed two years ahead of the national “Eleventh Five-year” wind power development plan; 2007 “renewable energy sources and long-term development plan” has been put forward in 2020, the National Wind Power the total installed capacity of 3,000 MW target, but the target could be completed this year.

Conditions for development is limited

However, wind power development is not without bottlenecks, resource and grid problem is that the two major problems.

The Zhangjiakou Municipal Development and Reform Commission officials reminded the journalists, although in Zhangjiakou in 2020 to go to 10 million kilowatts installed capacity, but also the local wind resource of approximately 16 million kilowatts.

Inner Mongolia Electric Power (Group) Co., Ltd., general manager Zhang Fusheng has said that wind power in Inner Mongolia last winter and spring Restricted situation will be very serious, “requirements and network operation of wind power capacity has more than 4.3 million kilowatts, accounting for the maximum power supply load 27% of the power grid far exceeds the capacity of Inner Mongolia (China EPRI demonstration capacity of wind power in Inner Mongolia Power Grid 8% to 10%). ”

Wind power transmission link is not fully accessible

Hebei, the existing two main power grid system: Tianjin-Tangshan power grid in Southern Hebei Network (Baoding, Shijiazhuang, Xingtai, Cangzhou). The Zhangjiakou Municipal Development and Reform Commission officials said the Beijing-Tianjin-Tangshan Power Network could not tolerate wind, and the future of Zhangjiakou may be issued by the wind into the Southern network, but now uncertain.

Gansu’s wind power will have to adopt a “Western Electric Delivery” approach to digest. Gansu Power Grid’s electricity load is now more than 800 megawatts of wind power generators installed capacity by 2010, the local capacity may be built is 500 million kilowatts, the power balance from the point of view, almost impossible to absorb wind power.

Gansu Provincial Power Company Wind Power Technology Center, a charge also told this reporter: “Gansu Province, a land wind power are difficult to digest, but should be in a larger context of the Northwest Power Grid where to strike a balance, involving areas including Shaanxi, Qinghai, etc. land, even to the central Sichuan, Hubei and Hunan regional transportation. ”

He said the next step is to direct the building of a base in Jiuquan, Gansu Province special high-pressure projects, wind power may go to East China and Jiangsu provinces and cities, “Of course, 500 million kilowatts of wind turbines can not, as thermal power, adequate, and this transmission side, the pressure smaller. If the wind unable to pronounce, but also can be taken to the extreme method of thermal power compression. “

January 21, the French wind turbine manufacturer and installer Vergnet Group, has won orders for three million euros, will be the southern Afghan province of Adrar construction of 10 MW, 10 HP wind turbine station in Algeria the first one.
The project through international competitive bidding, with a total investment of about 3 million euros. French Vergnet company total investment advantages from the operation of the electricity prices and the cost of kilowatt-hour price advantage over major competitors – Germany’s MAN Forrostaal company won the bid in one fell swoop. Wind power plant covers an area of 30 hectares, in 2012 put into operation. Adrar energy produced will be incorporated into the provincial power grid, which will greatly reduce the area of energy.
Vergnet the French design,  wind generators manufacture, sale, installation and maintenance of wind power equipment industry consortia. So far, the global production and installation of 500 wind turbines, each producing 15 million MWh of electricity. Recently signed with Ethiopia, duration 36 months, 120 MW, cost 210 million euros in wind power plant turnkey construction contracts.

Recently, a wind power plant built in the Antarctic began to run, this can be regarded as the world’s wind power plants in the southernmost. The purpose of the establishment of this wind power plant is to solve a very cold regions of the power supply problems in the hope to change the status quo reliance on diesel.
The wind power plant located on Ross Island, formed by the three turbo-generators. As being located in the Antarctic, the wind power generator plants will face a tough test from the environment, where temperatures as low as -57 ℃.
The wind power plant construction and operation of the company, New Zealand, power companies, project leader Bennett said that if this power plant has been verified to establish a viable, then it will be possible to promote in the Antarctic. He said: “We will use the time to observe the year of the effectiveness of this power plant, and then to assess.”
Reportedly, the wind generators plant will be built in New Zealand and the United States Maike Mo Scott Base research station provided more than 11% of the electricity supply, an annual reduction of 46 million liters of diesel consumption.
In addition, Bennett also said that the establishment of solar power plants in the Antarctic is also within the scope of their consideration.

January 18, the European Union Wind Energy Association (EWEA) published the “2009 European Union annual report of offshore wind power development.” According to the report, the European Union in 2009 the total installed capacity of offshore wind power generation increased by 54% to 577,000 kilowatts.
The rapid development of offshore wind power generation
According to the report statistics, in 2009 the EU wind power, especially in the field of offshore wind power generation has developed rapidly. European Union in 2009 a new wind farm 8, the new offshore wind turbine generator 199 units. In 2009 the total European offshore wind power capacity reached 57.7 million kilowatts, compared with 2008, 373 thousand kilowatts up 54%. In addition, EWEA is expected to be completed by 2010, the European Union will also be 10 new wind farm, the total installed capacity is expected to exceed one million kilowatts.
At present, the European offshore wind farms under construction in a total of 17, the total installed capacity of power generation market to reach 3500 MW, of which more than half of the wind farms are built in Britain. In addition to built 17 wind farms, the EU has approved the establishment of a wind farm there are 52, the total installed capacity of up to 16 million kilowatts. There are also a number of wind farm construction plan is being worked out. The wind farm will provide the European Union more than 10% of the electricity supply.
Not only are more and more, the European Union in the new scale of wind turbines farms is also growing, in 2008 the European Union average of new wind farms installed capacity of 6.2 million kilowatts, whereas in 2009 it rose to 7.2 million kilowatts.
EWEA said that the need for more investment in wind power development
EWEA CEO Christian right in the European Union in 2009 the development of offshore wind power generation, said sure, but he also pointed out that despite rapid growth, but the EU member governments should continue to support offshore wind power development. He said: “Taking into account the establishment of large-scale wind farms in the financial and technical difficulties to be overcome, we have achieved in 2009 is incredible. In order to encourage wind power industry development, the Government should continue to provide a political framework for more help to attract more investors to enter this field. ”
In the fiscal revenue side, according to EWEA statistics, offshore wind power in 2009 brought the EU total of 1.5 billion euros in revenue. Taking into account the large number of EU electricity by 2010, the company will expand their business in North America and Asia, EWEA is estimated that in 2010 this income is expected to increase to 30 billion euros. Of course, the Government’s support is important because these projects are usually the biggest problem is funding. Worked six wind farms injection group of the European Commission said the recovery plan, will continue to increase investment in this area, but also the European Investment Bank, said of the wind power generator investments.
Recently, the European Union nine countries signed an agreement to build in the North Sea agreed to study the feasibility of UHV grids, which is seen as the European Union an important breakthrough in the development of wind power generation. In addition the European Investment Banking will also provide a similar connection to the United Kingdom and Norway, wind power project investment 300 million euros, the project also was optimistic about the outside world.
Kristen believes that more and more money into shows that policy makers clearly wind power will be the key to EU’s future energy supplies. He said: “As more and more capital investment, the wind turbines continuous development of the field of wind power will provide the EU to bring in advanced technology, more job opportunities and economic recovery.”
