18 八 10 Build a giant offshore wind turbines
British company is working to design a large-scale wind turbine, its wingspan of up to 275 meters length, power generation capacity will be an ordinary wind turbine 3 times.
In the current trend of promoting green energy, the UK, U.S. and Norwegian engineers is undergoing a giant home wind turbines of the contest. British Arup-designed building in the sea of this new type of turbine generators (Aerogenerator X), power generation capacity of 10 megawatts, a huge machine of its size is twice the normal model, I believe because of this global energy market New wind generator and change.
Blade span 275 m
This simulation rotation sycamore leaves inspired by the floating oil platform technology. Technological leadership in the Arup engineering company with the Rolls-Royce, Shell and BP, including several blue chip companies funded by academic groups, such detailed design of wind turbines, the wind turbine generators axis to the rotation leaves a wingspan of up to 275 meters. Preliminary estimates, after two years of testing, the first generating unit will be completed.
However, the British design team, including the design of the Garden of Eden Project and Grimshaw Architects have to heated competition of other groups. Earlier this year, and the U.S. Department of Energy’s Renewable Energy Laboratory, U.S. close to Clipper Wind Power Inc. announced that they would plan to build North East of England called “Great Britain” 10-megawatt wind turbines.
The traditional scaling of small wind turbines is the popular practice of the United Kingdom, these behemoths will be fixed on the seabed, about 600 feet above the waves.
Clipper claims that, if technically and economically feasible, each unit in its 25 years of useful life and can supply electricity generated from 5000 to 10,000 families use, the equivalent of 200 barrels of oil produced energy.
Competitive market
At the same time, Norway’s Sway company plans to build giant floating turbines, this turbine directly connected to the 100 m deep sea bed, called “mast” of the anchor. 1 Research Institute funded by the EU program also manufacture 8-10 megawatt turbines generaotor In addition, the United States and Denmark, some companies are going over from fat, 9 MW unit of work. All of these design full-size model will be completed in three years.
Offshore Engineering Cranfield University, UK head of Furge • Brennan said: “A wonderful intense athletic competition is staged. The winner of this contest will have access to the global offshore wind turbine market dominance.” Cranfield University has completed a number of wind turbines over from hair work. He said, “Britain’s offshore wind power generation may start some of Jae-man, but with four years of gas oil mining experience, we still have the opportunity to lead the world. The new vertical wind turbines is a type of oil in the semi-submerged platform technology based on the construction of and there was no tradition of wind turbines in the weight limit. newly designed turbine with its high level of conventional turbines only half. “He also added that the extension of this technology, it can produce 20 megawatts or more wind turbines.
Renewable energy future
Currently the largest installed wind turbines in the rated power of about 3 MW. In contrast, thermal power plant was already out on the gigabit level, about 180 sets of this new type of wind turbines in Scotland North Ayrshire was the equivalent of a coal-fired power plant capacity.
Engineers believe that wind power is OK, the key lies in the construction of the scale. The traditional double the size of wind turbines, in theory, can produce four times the wind, but at the same time the weight of wind turbines and the cost will increase eight-fold. As the sea to receive an endless supply of wind, the sea transportation and installation of large equipment and more convenient, and this is also a rare public objection, which is widely regarded as offshore wind power renewable energy future.
On land, the huge leaves of the transport and lifting equipment are required to hell and high water, and the approval of the plan often takes several years. However, the current installation of offshore turbines than land-based wind turbine comprising the three Zhiwu Cheng to be expensive and difficult to maintain, but also vulnerable to corrosion.
It is estimated that offshore wind power generators market will be several hundred billion dollars per year growth. Last year, the European Wind Energy Association expects Europe’s offshore wind power installed capacity will be from the current 2 megawatts of growth by the year ○ 三○ 150 GW or more years.
Although Britain has not required the construction of large-scale high wind areas and space, but the British in the Second ○ ○ 八年 in offshore wind electricity generation beyond Denmark, and to 330 units of capacity to lead the world. In addition, the United Kingdom has developed a vision of developing wind resources to plan, they expect to in the Second ○ 一 二年 made up offshore wind capacity to 12 GW. This is equivalent to 2,500 units installed in the largest 5-megawatt unit.
Greenpeace UK head of John • Shu Wen said: “We demand for energy will be counting on that here, but the key is the British Government can not cut in order to obtain short-term interests of the budget in order to hinder the development of offshore wind power.”

14 五 10 Offshore wind turbines hampered by three factors
Currently, China’s offshore wind power generator will not develop too fast, primarily due to equipment, engineering, pricing policies of three factors hindered.
Xie Changjun in the “green economy and international cooperation to address climate change conference” Five minutes after the Forum accepted the China Securities Journal reporters. He said that Long Yuan Electric Power in the interest of the development of offshore wind power, tidal zone project is progressing well. China Wind Power Technology Co., Ltd. Rui Tao, vice president just believes that coastal wind power base due to local demand greater pressure on the infrastructure is relatively smaller. Insiders pointed out that this also determines that China will intensify efforts to develop offshore wind.
But Xie Changjun also held that because the offshore wind generator equipment manufacturing is not yet ripe, offshore windmill power project construction technology to be improved, and the state has no corresponding price of offshore wind power online, these will hinder offshore wind power, as in recent years as high-speed land-based wind power development.
Xie Changjun also speech that the current development of China’s wind power problem. First, power is limited, one technical problem, and second, the core issue of economic value, due to wind turbine generator companies to receive the benefits of thermal power to receive the benefits as well, so the enthusiasm is not high. He believes the Government needs to do the work in the policy, so that acceptance of wind power in the lucrative, to the development of new energy policy can be a very good offer.
Second, the quality of wind power equipment to be tested. Xiechang Jun said that China Long Yuan Wind Power Company the oldest and largest wind power company, which runs the first wind turbine has been 17 years, made a large number of units is running 3 to 5 years, some quality problems still need to test, bring on the future development potential pitfalls.

11 五 10 Onshore wind turbines farms into the grid deadlock
Lack of coordination, China’s largest land-based construction wind farm into the grid deadlock. China Wind Power, “a large-scale, highly centralized development” model is the time to reflect on it?
Jiayuguan Great Wall, the most western from proceeding along the winding highway driving, with the only one that stretches the endless peaks and the vast expanse of Qilian Gobi desert. After more than an hour’s drive, the large shining white of the fan in the Vision.
This is the Yumen Changma wind, Jiuquan City, the two most concentrated base of wind generators Back in 1997, four imported from Denmark Nordtank fans had stood in this land over, and so far. They each generating power is only 300 kW, then the source of wind power company in Gansu Jie introduced.
This extraordinarily compact four fan has turned 13 years, also witnessed the birth of a wind power of the Kingdom. By Long Yuan Electric Power operating in the field of wind power this film has more than 100 wind turbine is running. In addition to these four small fans, the rest are to be much higher in the 750 kW or 850 kW fan. While not far away, is 10 million kilowatts of Jiuquan wind power base in the start-up projects, namely, China Energy Conservation Investment Corporation and Hong Kong joint venture wind farm construction. 134 1500 kilowatts of fans formed a large square arrangement of 50 square kilometers of land, spectacular.
“World outlet,” said the Yumen, the south Qilian Mountains (600,720, stock it), north Mazongshan, forming the “two mountains and one trough,” the natural channel, both from the east of Inner Mongolia, but also from Xinjiang westerly. Today, the unique Yumen wind turbines resources, including people from the Long Yuan Electric Power, the energy, Datang, Huaneng, China Light and Power International, Huadian and CNOOC and a number of central enterprises stationed, and to carry out wind power projects.
Guazhou in Yumen west, then the more “World Wind Library” is known, is another major city of Jiuquan wind power base. China Guangdong Nuclear, China Power, Long Yuan Electric Power and other wind farms already operating and net electricity generation, while the other series in which the central enterprises have gradually been settled.
This is a comparable wind power base of the Three Gorges Hydropower Station, the 10 million kilowatts of wind power base level has a resounding title, the “Wind Power of the Three Gorges.” The local government is also quite thought-rong, “Jiuquan wind power base of 10 million kilowatts is China’s first, is the world’s first.” Jiuquan city stakeholders on the “energy” magazine reporter said.
However, this pioneering wind power generator base was recently accused of “image projects.” Remove sand and other natural and technological disadvantage, the more convincing the opposition is – caused by overheated investment in wind power idle fan the pain of the fact that the Internet has let the “wind of the Three Gorges” exerted pressure on leaders .
Opponents are emphatic leader strongly refuted – that the Japanese director Akira Kurosawa’s film “Rashomon” in very similar circumstances. Well, the truth?
Hot
Located in the Hexi Corridor in Gansu Province in Northwest inland area west of Jiuquan in China’s five cold effect one of the source, is China’s wind energy rich region.
“In the past, this wind was a lot of people”as a kind of wind damage ‘, because it will bring a variety of production loss.” Jiuquan, a local government official said. However, heat wave hit in the new energy of today, this is a rare precious resource.
Back in 1997, began testing the waters of Jiuquan wind power industry. However, by 2006, the installed capacity of Jiuquan City, before more than 50,000 kilowatts. Until three years ago, the Jiuquan wind power industry started to really take off until 2008, the city has reached 510,000 kilowatts installed capacity.
In 2009, the Jiuquan wind power base of 10 million kilowatts is started. May 2009, the State Development and Reform Commission approved the Jiuquan wind power base of 10 million kilowatts, “Eleventh Five-Year” 3.8 million kilowatts wind power project, a wind began to really rise of the Kingdom. Including five power generation groups, China Guangdong Nuclear Power, the energy, CNOOC, China water investment, construction, etc., of water in the central enterprises poured in from various quarters, and a circle have their own place. A mammoth project in the Gobi Desert northwest inland in full swing.
Stationed in Jiuquan wind power base of investment business they are engaged in business confidence. For wind farm development in the Gua operation China Guangdong Nuclear Wind Power Co., Ltd. related to the “energy” magazine reporter, the company has been completed, production capacity is running at 10 million kilowatts. Dry mouth are building capacity of 200,000 kilowatts of project design, ongoing tension in the lifting, put into operation in October this year. Their plan is to Gansu million kilowatts of installed capacity eventually.
The construction of wind power projects is driven industry and supporting industries related to the overall development. In the project construction, equipment purchase is the largest piece of the cost. “A 20 MW wind farm construction costs 9000 yuan per kilowatt. To include the host, hub, blades and tower tube and some other fans, including the total cost of procurement accounts for more than 70%.” Jiuquan, a local head wind farm on the “energy” magazine reporter said.
So the scale of Jiuquan more than 10 million kilowatts of wind power turbines and equipment needed places close to the total value of 100 billion yuan. Jiuquan city naturally want to develop wind power equipment industry, promote local manufacturing industry. Jiuquan local government in its industrial park set aside large tracts of land, specifically for its wind power equipment manufacturing industrial park construction project. To date, Sinovel, Goldwind (002,202, stock it) and other fan manufacturers and Sinoma Science and Technology (002,080, stock it), the aircraft manufacturer Hui Teng settled one such leaf. Host, hub and blade makers are concentrated here, and in other parts of Jiuquan Yumen so, then some tower tube manufacturers.
Jiuquan wind power sites used by local fans for more than 80% of localization has been achieved from all over the country’s major manufacturers. For these companies, in Jiuquan fans locally produced, cost more evident than in off-site after production and lower transported to Jiuquan.
In the vast Gobi desert on the outskirts of Jiuquan, a seat factory where they stand. The largest fan manufacturers Sinovel production has reached base in the six months. Huge factories, machinery roar. 1500 kilowatts a central component of the fan wheel hub from the host and the output here, the supply of the Jiuquan wind is constantly expanding. Last year, the base of the first 3,000-MW super fan has been off the assembly line, production work is being carried out now, ready to supply a full implementation by the fan 100 MW demonstration wind farm.

23 四 10 China electric wind turbines instrument business into harvest
Of the wind power industry, 2009 is not a good prosperous years, intense market competition and price fluctuations machine, are greatly weakened the wind industry’s gross profit margin. However, wind power, including state regulation of excess capacity, new technology breakthroughs, and China is expected to wind turbine electrical apparatus as increases in orders, 2010, China Electric usher in a new instrument development opportunities.
“Wind power capacity will be expected to accelerate development to keep pace with high-voltage switch business.” Hua Jiang Fujun instrument electrical secretaries to directorate told reporters.
Traditional business and wind power generators business
This year is expected to keep pace
Chinese Instrument Electric annual report for 2009, 1.198 billion yuan last year, operating income, up 54.6%; net profit 89.4098 million yuan, up 14.64 percent. Among them, two wind power blocks of business are the main high-voltage power distribution products, and wind power. From the Annual Report of view, the two main business electric meter, the traditional high and low voltage power distribution products is still the main source of profit. Report shows that high and low voltage power distribution products, operating income was 679 million yuan, 494 million wind turbine group, there is another piece of independently developed software products, operating income for 2009, 6.29 million yuan.
Although the results from the 2009 run, is still the traditional high and low voltage distribution products as the leading, but this year the wind turbines business with the Chinese instrument explosive growth pattern will change significantly. Corporate Annual Reports, this year’s overall business towards more than 20 billion revenue, business scale wind turbine will maintain rapid growth, the traditional high and low pressure is expected to be split evenly and wind power, basically the same sales volume.
At present, the Chinese wind instrument electric power business, mainly from its lung power of 1.5MW in 2009 won the order has reached 120 fans around. According to GF Securities researcher Li Weiqing analysis, order the existing fans, coupled with the second half of the company’s manufacturing base can Tongyu production, will also direct access to 50,000 kilowatts of order, consider the first half of the wind generators farm Investment tender peak meter to get this year China produced 200 sets of orders and sales are high probability events, its wind power business in 2010 on sales to more than 1.3 billion yuan.
“This year get orders is transparent, the only can not determine that the order has been received in that year profits would not necessarily realize that some orders may be delayed until next year to deliver.” Jiang Fujun said.
In the traditional development of high and low voltage parts, electrical apparatus and China did not give up, “after all, which started the main business, will not give up.” Jiang Fujun said: “The high and low voltage components in the sales area has also been a breakthrough and began to enter the petrochemical industry and try to enter the high-speed railway, real estate and other industries, sales this year will be a breakthrough. “
