05 八 11 Sinovel took full advantage of the boom in the Chinese market
Vestas is still the world’s top wind turbine generator manufacturer in terms of its percentage of market volume, but GE Energy lost its title as the second largest supplier to China’s Sinovel. Together Vestas and Sinovel delivered 10,228 MW of capacity in 2010. The two leading suppliers’ share of the total deliveries to the market was 25.9 percent in the year, which is a one percent increase compared with that of 2009 from the two players.
Sinovel took full advantage of the boom in the Chinese market, enabling it to move up from the third position in 2009 to second in 2010. Conversely, GE Energy dropped to third place due to the economic downturns in the US market. And, GE Energy is closely followed by another Chinese supplier, Goldwind, which installed almost the same number of turbines as GE in 2010. German Enercon ranks at No. 5 in the world, and is followed by Indian-based Suzlon Group at No. 6.
In their home wind power generator market Chinese domestic turbine manufacturers made further gains, while foreign-owned manufacturers only achieved a 10.5 percent market share in 2010 – a 3.5 percent drop from the previous year. Along with Sinovel and Goldwind, two other Chinese wind turbines manufacturers were listed in this year’s top 10 in terms of global capacity delivered. Dongfang, the third largest Chinese manufacturer, first entered the top 10 list in 2009, and United Power entered for the first time in 2010. Meanwhile, other Chinese companies Mingyang, Sewind and Hara XEMC, listed as No. 11, No. 14 and No. 15 in the world respectively, are emerging to challenge the positions of the traditional market leaders from Europe and the US.
It is worth noting that 2010 also saw more MW-rated Chinese manufactured turbines exported. During the year, five Chinese turbine suppliers installed 13 machines in five different foreign markets. Following its first three 1.5-MW direct drive wind turbines installed in the US in 2009, Goldwind installed six units of its 750-kW-rated gear drive turbines in Cuba. Meanwhile, Mingyang and A-Power installed their first wind turbines in the US market in 2010 and HEAG also installed three 1.5-MW turbines in Chile and White Russia.

01 八 11 Wind turbines are getting really big
Wind turbines are getting really big — some with blades as long as a football field — and more powerful, often generating 50 times more electricity than the first generation of wind-power machines built in the 1980s.
But scientists are also studying how to harness the wind in different ways that could help allay concerns that today’s turbines are unattractive, noisy and sometimes even dangerous.
Already in the works: Turbines that float and small wind turbines that fly. Turbines without blades and turbines with blades fat enough to fit a double-decker bus inside.
They won’t just be on hillsides either. Some will be in the ocean, while others will be on rooftops and light poles. A few will even be in the sky.
One design was inspired by the humble bumblebee.
Sabri Sansoy, a graduate of the Massachusetts Institute of Technology and former rocket engineer, has built a 19-foot-tall prototype whose blades, rather than spin in a circle, move in a figure-eight motion like the insect’s wings. Sansoy hopes the design will generate more electricity than turbines of similar size.
“I’ve been called everything from brilliant to a nincompoop over this,” said Sansoy, whose Marina del Rey, Calif., company, Green Wavelength, is looking to commercialize the technology.
But “there’s a lot of people interested in this kind of thing, taking energy out of the wind,” he said.
That’s because there’s a lot of money being poured into finding ways to ease off coal-based electricity. Last year, the Department of Energy set aside a record $79 million for its wind generators -program budget — nearly $20 million more than its previous top allotment in 1980.

12 六 11 China’s wind turbine manufacturing industry will undergo significant
China’s wind turbine manufacturing industry will undergo significant changes in the wake of new industrial restructuring guidelines which will come into effect on June 1.
China’s wind power industry, which has developed by leaps and bounds over the past five years, will have to follow a new series of guidelines and restrictions, according to the 2011 edition of the Guideline Catalogue for Industrial Restructuring, a set of policy guidelines recently released by the National Development and Reform Commission (NDRC).
The new guidelines state that “new energy” sources, including wind energy, shall be considered as a separate category for “encouraged development”. The 2005 edition of the guidelines stated that wind energy and other sources of clean energy would be grouped in with traditional sources.
Industry officials say that once an investment project is listed in the “encouraged development” category, the company or companies behind the project can enjoy preferential treatments such as floating shares in the stock market, lighter requirements for new bank loans and tax breaks.
However, under the new guidelines, China will not extend these preferential policies to companies that produce wind turbines with 2.5-megawatt-capacity or lower. Instead, the policies will encourage the development of larger-capacity turbines, as well as components for control systems and converters for these larger turbines.
“There is an overabundance of investment in emerging energy sectors, such as the wind power sector. This is the result of an influx of capital into China’s equipment manufacturing industry, which is operating under the idea that China has strictly controlled fixed investments in sectors that consume more energy and resources,” said the NDRC in its interpretation of the new guidelines.
“If we don’t regulate these sectors, companies will encounter problems in production and management. This will hinder independent innovation and restructuring,” the NDRC said.
In March 2010, the Ministry of Industry and Information Technology (MIIT) issued a circular in which it asked for public opinions on the management of the country’s wind power industry. In this document, the MIIT stated that new wind turbine manufacturers must have the ability to produce wind turbines with 2.5 megawatts of power generating capacity or higher.
Industry officials said that with the new guidelines, China has finished fine-tuning its wind turbine manufacturing industry’s policies, and that the production of outdated wind turbines will be eliminated.

05 六 11 Wind turbines manufacturers are feeling the industry
Wind turbine manufacturers are feeling the industry performance pinch for the first time after five years of good times in China, the world’s fastest-growing wind power market, said industry experts.
Following recent incidents where a total of 1,346 wind turbines generator were disconnected from the power grid on April 17 in Gansu and Hebei provinces, China is planning to issue stringent national standards for wind turbine manufacturers.
The incidents, which caused energy wastage, reduced electricity output to millions of customers.
The national standards, being drawn up by the government, are expected to set the tone in the industry, requiring that all installed wind turbines are equipped with low-voltage ride-through (LVRT) capability to ensure stability to the power grid.
LVRT refers to the capability of small wind turbines to maintain continuous operation during and after precipitous voltage dips, allowing the power grid to be adjusted more quickly and improve the overall safety and stability of the grid.
“This will put considerable pressure on wind turbine makers and wind farm operators to upgrade China’s 34,000 wind turbines,” said Li Yinghua, deputy director of the security regulatory bureau under the State Electricity Regulatory Commission (SERC).
Compulsory national standards for wind-generated electricity are needed to regulate grid compliance and build a strong smart grid in the country, industry experts said.
At present, most of China’s installed wind generatos do not have the LVRT capability and domestic manufacturers are upgrading their machines in the wake of the recent incidents in Gansu and Hebei provinces.
The State Grid, China’s largest power distributor, issued the current standards in practice for wind power operators in 2009, but these were not enforced nationally.
It costs between 10,000 and 500,000 yuan to upgrade a single wind turbine by installing LVRT, depending on the turbine model, said experts from Denmark-based Vestas Wind Systems, a leading international wind turbine manufacturer.
“Some turbine models merely need software upgrading, while others require much more than that,” said Shi Haifeng, an expert with the Finland-based The Switch, a leading supplier of wind turbine components.
Wind turbine manufacturers are capable of installing the LVRT technology but some wind farm operators do not want the function partly due to cost concerns, an expert from a European wind turbine manufacturer said.
“LVRT capability is not the only reason for the system’s failure,” said Qin Haiyan, secretary-general of the China Wind Energy Association. “Even with the technology, such disruptions are still inevitable because the power grid is a system.”
Meanwhile, the current standards also suggest wind farm operators to install the Static Var Compensator, which costs at least hundreds of thousands yuan and can maintain steady voltage and stabilize the windmill power system.
According to the European company expert who declined to be named due to company policy, the wind farms in Gansu and Hebei, where the disconnection took place, did not have the Static Var Compensator, which could help to regulate voltage and regulate the power system.
China increased its total wind power capacity to 41.8 gigawatts in 2010, up 62 percent from the previous year.

18 五 11 Europe has been operating wind turbines offshore for close to a decade
Given the commercial success of the global wind power industry in tapping resources on land, why move offshore, where the deployment challenges are so much greater? Many of the best land-based wind resource sites located close to urban centers of demand have already been developed, with remaining sites facing higher costs due to less attractive wind resource regimes and long distance transmission costs. Furthermore, the world’s best wind resources are largely untapped since they are located offshore, typically in shallow waters close to urban population centers.
Europe has been operating wind turbines offshore for close to a decade. The United Kingdom is the current market leader in Europe, with Germany also coming on quite strong. However, Pike Research forecasts that China’s offshore wind market will pull even with Europe’s two largest players by the end of the forecast period, with the United States trailing behind.

05 十 10 Wande by independent research and development, “Sailing with wind”
This year in April, the Shanghai Fengxian Hangzhou Bay, with completely independent intellectual property rights of 1.25MW, 1.5MW prototype permanent magnet direct drive wind power formally and power generation, which is a private venture, Shanghai Wande Wind Power Co., Ltd. developed the current generation the most efficient fan technology to leading domestic and international advanced.
The establishment of more than 5 million years of German wind power generators is the first large-scale independent in the permanent magnet direct drive wind turbine research, development, wind turbines manufacturing, sales and service integration of new energy enterprises, Hongkou District, Shanghai, and the key support level wind power high-tech enterprises.
Most domestic production of double-fed asynchronous counterparts of different fans, Wande wind power development is to follow a different path to the permanent magnet direct drive technology fan. Permanent magnet direct drive wind turbine rare earth raw materials required, our reserves of more than 90% of the world, million German fans have a lot of resources cost advantage.
More importantly, Vander wind generator aimed at the world technological frontier, breaking multinational technology blockade, independent of the successful production of a variety of models with completely independent intellectual property rights of a large permanent magnet direct drive wind turbine.
Permanent magnet direct drive wind power generation is a contemporary grid wind power technologies one of the most advanced technology, on behalf of the future grid large scale wind power generation technology trends. Million in 2005, when the German wind power company was established, permanent magnet direct drive wind turbines in the most advanced wind power technology has just appeared in Europe soon.
Permanent magnet direct drive wind turbine generator rotor and the motor is a coaxial connection, that wind round without a gear box variable speed, direct-drive motor with the speed of rotation, so it has produced most domestic counterparts doubly fed induction small wind turbine can not be compared advantages: low-speed startup, small volume, power generation, high efficiency, low maintenance and operating costs, easy to transport, and large supportive of the power grid to meet the most stringent European standards.
In Denmark, Germany and other European countries, direct-drive permanent magnet wind turbine installed capacity of large-scale wind power accounted for about half of the total installed capacity, and some European countries have the second-generation models as the backward doubly fed induction wind turbine technology be eliminated.
Technology to overcome the blockade of foreign enterprises, China’s own development of entirely permanent magnet direct drive wind generator, wind power for a million German establishment began to take risks to embark on independent research and development and innovation.
In 2005, the million German wind power commitment of Shanghai Science and Technology Commission, “the development of large permanent magnet direct drive generator” task, and completed in April 2006 China’s first with completely independent intellectual property rights, and Net-based 125 MW direct-drive permanent magnet wind turbine prototype development, such domestic products to fill gaps in one fell swoop.
April 2010, to install offshore wind farm in Fengxian District, Shanghai grid of these two megawatt machine is running very good, the indicators are at or better than the design standards, showing not only the wind farm on land use, more suitable for better use of the intertidal zone of low wind generation capacity.
Wande permanent magnet direct drive wind power wind turbine working principle of the decision of its own outstanding wind its utilization and generating capacity, no gear box design is greatly reduced in the natural environment particularly prone to fan failure probability Therefore, considering the initial investment and long-term operation and maintenance costs, without paying patent fees and other foreign income, the overall power situation, Wande direct drive permanent magnet wind power has obvious cost-effective models.
