Wind Turbines Manufacturer in China

Laizhou City, completed a total of  wind turbines generating capacity 5938.868 kwh, the highest capacity high.

Town is located in the coastal areas of Laizhou earth wind generators farm wind turbines were installed 39 units, with a total installed capacity of 48.5 megawatts. Period of good wind for safe operation and protection work, struggling to minimize power outages, many wind power generation, to ensure the quality of wind power generation. Laizhou Wind Farm to break the previous run maintenance mode to protect the safety of electrical equipment and personnel under the premise of taking 24-hour reset the fan blower to reduce downtime as much as possible, so that power loss to a minimum. Winter favorable wind resources, wind farms to create the conditions for the overall operation. From November 2 to November 8, Yantai and Laizhou Dongyuan Wind  generators Power Group, 19-turbine wind farm within a week completed a total of 2.52846 million kwh electricity, the highest since the weeks of the commissioning of new generating capacity is high; November 9days to complete generating capacity of 997.26 thousand kwh, the highest daily production capacity has been high. As of the end of October, Laizhou completed a total generating capacity of wind farms 5938.868 kwh.

From Hohai University, efficient use of water resources and Engineering, National Engineering Research Center Security jointly developed by the Chinese wind turbine has been a major breakthrough in key technologies with independent intellectual property rights of 10kW vertical axis wind machines have been developed and manufactured, and sold to the European market.

China’s wind generators industry has developed rapidly, in 2008 the national total installed capacity of wind power to reach 12.2 million kilowatts, is “Eleventh Five-Year Plan” task two times. In 2009 the national total installed capacity is expected to reach 20 million kilowatts.

Statistics show that domestic wind turbines machine manufacturing enterprises with more than 70, more than other parts of the world’s total wind power equipment manufacturers.

However, the core technology and key components, the various enterprises is the introduction of route to go. Rely heavily on the introduction, the core technology and independent innovation capability deficiencies, resulting in high cost of wind power. The key to the wind turbine technology for basic research on China’s wind power development significance.

According to Water Resources and Hydropower Engineering, Hohai University, Professor Zheng Yuan, at present the large-scale wind turbines are horizontal axis wind turbine. But the horizontal axis wind turbine design technology complex, dozens of tons of weight to be installed in the cabin altitude of nearly 100 meters, the power exists yaw losses, these are the domestic causes of the higher cost of wind power.

In China, developed its own vertical axis wind machines without the need for wind, there is no yaw power loss; blade design is simple, completely self-design; cabin and gear box can be placed under the wind wheel or on the ground, maintenance costs, lower; vertical axis wind turbine noise smaller than the horizontal axis, noise pollution, reduced; In addition, laboratory studies have shown that the wind energy utilization coefficient of not less than the horizontal axis.

“Calculated and experimental results prove that the design of the spiral optimized S-type wind wheel wind than traditional S-wheel wind energy utilization of a net increase of 6%. This is in terms of S-type wind turbine is a very significant improvement.” Zheng Yuan said.

But here, some experts also said that wind power equipment manufacturing industry is relatively weak. Some developed countries, compared with foreign countries, China’s wind energy development, whether in technology, scale, level or speed of development, there is a wide gap. The low level of power generation equipment at home to become China’s wind power industry of the main obstacles.

Due to lack of long-term investment, China’s wind power equipment manufacturers to produce relatively small size, less intensive, product quality is not very stable, cost-effectiveness is also relatively low. High costs, high prices are constraining wind power technology commercialization and promote the use of the the biggest obstacle.

Business degree from a technical perspective, wind turbine life expectancies, it is difficult to ensure that technical service life of 20 years, hence the need to improve the reliability of all components. This can be through the fan system optimization design, selection of better materials and advanced controls and other measures to achieve.

Electrical equipment manufacturers the world’s power has the upper hand in Germany, Spain, the Netherlands, Denmark, the United States and other countries in the world could be utilization of wind from the original 50% to 98%, wind energy utilization coefficient of ultra-40%.

But in recent years, China’s wind power equipment and technology to improve and manufacture of rapid progress. In August of this year, Liaoning Province, Shenyang City, China Chong Wind Energy Co., Ltd. have complete independent intellectual property rights of the 20 units 1.5 MW wind turbines in Inner Mongolia recently Saihantala wind farm commissioning successful, the first group of 240 hours have passed the acceptance the successful realization of the grid. The 20 wind generators, the whole cost of wind turbines than abroad reduced by 20% to 30%, the average utilization rate of 99.64% and the fans.

Wind power generation due to unpredictable winds, making wind turbines the Internet is evolving into oscillation, when the wind power system disturbance frequency close to the inherent oscillation frequency, can cause significant power oscillation, and the oscillation amplitude as the disturbance will be the magnitude of change. Perturbation amplitude not only with the wind generator disturbance, but also with the parameters of the system itself, and therefore could be considered two-pronged approach to reduce disturbance on the power grid forced oscillation. Wind power will not only have forced oscillation system to produce, but also the transient stability of the system have an impact. Of course, this effect is small in wind power installed capacity is negligible, but when once the wind power in the system occupies a relatively large number of shares, this effect can not be ignored, otherwise the grid when a sudden change of wind power, the system There may be too large due to oscillations can not remain stable and transient loss of stability, and there the collapse of large power systems. In short, if and to network with higher share of wind power is rather weak, and the net negative impact is enormous.

Great efforts to develop wind generators as a clean energy has been wind power issue has become increasingly subject to the power of staff concerns. But the wind as an intermittent energy sources, combined with the forecast accuracy of wind energy resources can not be fully in line with the power system to the power quality requirements, to seek new ways and new thinking to resolve the impact of wind turbines on the system naturally becomes the work of a number of the power industry personnel targets. Use of static VAR compensator can quickly compensate for reactive power, wind power generation to maintain a stable power supply voltage of the access point, but can not adjust the active power output of wind farms. The use of battery energy storage system can be a better solution to this problem, and can guarantee the stability of the Internet voltage, but also can compensate for active power, the system will not be adversely affected. May choose from a battery, rectifier devices and inverter device composed of flexible AC transmission system as energy storage system.

2009 is the year of new energy. Wind power generation is the main force of new energy sources. Wind turbines industry development planning in recent years has repeatedly adjusted to achieve a high growth doubling year after year. Experts predict that the next 10 years to 20 years, there will still be large-scale development of wind power. On the one hand the domestic wind generators industry is in full swing to build, while the other hand, fell into wind power equipment, the cycle of excess capacity.

Fan manufacturing industry barriers to entry is low, the current domestic wind power generator manufactured in nearly 70 companies, which more than 70 machine manufacturing enterprises 80% are simple assembly plant. Technology re-introduction, lack of self-innovation capability is a common problem of these wind power companies, while the introduction of professional knowledge, work experience, talent is the best wind power an effective way to change the unfavorable status quo.
However, the wind turbines industry, talent shortage is global, and China now there have been such a situation. The lack of professionals has become a bottleneck in the development of wind power plant industry. Wind power professional and technical personnel, designers and developers, industry management talent, and so the relative scarcity of after-sales management personnel.

But also be conducive to the good news, the domestic many colleges have set up wind generator expertise. Polaris electric power networks of excellence, according to recruitment consultancies, North China Electric Power University, 2010 Bachelor graduates in the forthcoming session of the wind power to market.
Polaris electric power networks of excellence from the data showed that many wind power companies have issued the demand for wind power talent, there are many gold wind science and technology, Chinese instrument electric, 31 electric, Zhejiang arrived, Shanghai Electric and other domestic wind power giant.wind turbines business-to on-site engineers, maintenance engineers, and so demand for engineering talent relatively large, for mechanical design engineers, electrical design engineers and other technical R & D Talents demand is relatively large..

News from the statistics department, said in the first three quarters of the Urumqi Economic and Technological Development Zone, the economic value of wind power industry 10.8 billion yuan, an increase of 132%.

Among them, Golden wind turbines science and technology in China’s wind power generating units of the total production and additional production volume in the first half of this year ranked first in the country. As China’s current wind generators equipment manufacturers, leader of a group, Goldwind Technology Co., Ltd. With independent R & D and marketing capabilities, market performance for eight consecutive years more than 100% increase.

Xinjiang Urumqi Economic and Technological Development Zone, an active extension of wind power equipment manufacturing industry chain, construction, wind turbines industrial parks, and proposed to build the “China Wind Valley” of the strategic objectives, has attracted a Ailm, Multi Tone, Xin Feng, and a group of Wind power machine supporting domestic and international famous enterprises stationed in parks, wind turbine production in the forefront among the Chinese.

Xin Feng installation is to make use of wind turbine loading and after-sales maintenance services to implement grew up supporting enterprise, Today, the company’s wind power business has been all over the country to install a number of wind power manufacturer, for 3 consecutive years to achieve over 50% growth in core business . Up to now, Xin Feng installed inside and outside the installation of various items at the provincial total installed capacity of wind turbines to reach 1.6 million kilowatts, the company cost-effective for one year a new level.

Goldwind supporting the Danish LM Xinjiang production of the first half of the company’s fan blades also achieved double-harvest production and sales. Golden Wind technology has successfully developed their own successful 1.5 MW, 2.5 MW Direct-drive permanent magnet synchronous wind turbine, 3.0 MW generating units are being developed, while still in high-capacity offshore wind turbine research and development.

China’s abundant wind energy resources and development potential. Preliminary estimates, the country’s land on the ground 10 meters altitude, the wind energy resource of about 3.226 billion kilowatts of total reserves could be the development and utilization of wind energy on land reserves are 253 million kilowatts. Including the sea, wind power generation in China can be used for a total installed capacity of wind farms of over 10 million kilowatts, equivalent to about 50 the Three Gorges power plant capacity.

2009 to 2010 domestic new wind turbines installed capacity will maintain an average annual growth of 30%

In 2007, China’s wind generators installed capacity reached 5.903 million kilowatts, when additional installed capacity of 3.304 million kilowatts, an increase of 127%, achieved three years ahead of “Eleventh Five-year” wind power installed capacity of 5 million kilowatts goals. By the end of 2008, China’s total installed capacity of wind power there is no suspense to break through 10 million kilowatts, two years in advance to reach this year, revised the “Eleventh Five-year” planning objectives.

Domestic demand is expected to wind power generator installed capacity between 2008 and 2010 to sustain rapid growth. 2008 new wind power installed capacity of 5.5 million kilowatts, up 60% from 2009 to 2010 the domestic wind power equipment market is expected to continue to maintain an average annual growth rate of 30%.

2011 to 2020, China’s wind turbines installed capacity of wind power added an average annual increase of 10%. Corresponds to the end of 2020 the total installed capacity of wind generators in China 190 million kilowatts, power generation accounts for more than 5%. In my opinion, the National Development and Reform Commission in 2020 to 100 million kilowatts of wind power generating capacity planning partial conservative, according to this plan, the total installed capacity of wind power generation accounted for (1.2 billion kilowatts) the proportion of about 8%, electricity generation accounts for only 3% compared with , far below the global level.

Japan’s Mitsubishi Heavy Industries has also stepped up its offensive in the Chinese market. Yesterday, Mitsubishi Heavy Industries and the Yangtze River Three Gorges Project Development Corporation held a relevant technical exchanges, specifically to understand the Chinese market for the fan status of the actual needs of a variety of devices.

Mitsubishi Heavy Industries is Japan’s only large-scale wind turbine manufacturer. In 2007, Mitsubishi Heavy Industries authorized Ningxia wind  Power Generation Group, a wholly owned subsidiary of Silver Star Energy Wind Power Equipment Manufacturing Company producing its 1MW fans, now the Sun Mountain in Ningxia to run 5 Mitsubishi wind turbine.

Mitsubishi Heavy Industries, yesterday revealed that Mitsubishi is developing a rated output power of 5-7 MW-capacity wind turbines, the wind turbine’s rotating blades diameter of about 130 meters.

As the world energy structure dramatic change, human environmental awareness is growing. From fossil energy systems to renewable energy-based system into a sustainable new energy. Among the many new wind generator sources, at present the fastest-growing commercialization of the most extensive and economically the most appropriate course ought to wind power. To this end, Xiji County in 2008 through the introduction of Investment Moon Mountain wind power project is the introduction of our county in recent years, the major projects.

Moon mountain breeze Xiji County power plant construction plan has been completed the preparation and adoption of Development and Reform Commission review of the autonomous region, autonomous regions and Academy of Agricultural Sciences is being commissioned to conduct the EIA report preparation, and strive to complete before the end of this year development plan approval, declaration and other preparatory work for the approved , start construction early next year and put into use.

The project by the China Huadian Group’s investment in Ningxia branch building, a project in the Mountains of the Moon New 49.5 thousand kilowatts of wind turbines plant 1, and supporting the building of wind power generation equipment, erection of transmission lines, hardening into the factory roads, etc.; project construction estimate requires an investment of 483 million.

At present, the project preparatory work steadily. After the completion of the wind generators plant can take full advantage of the rich wind resources, Mountains of the Moon, the annual 104 million kwh electricity access for the county’s economic development provides ample power to protect.

For China’s wind turbines equipment manufacturing enterprise development status of China Association of Resources Comprehensive Utilization of renewable energy Zhu-sheng, director of Professional Committee of China’s wind generators equipment manufacturing industry is still in development stage, a good momentum of development, but also a lot of problems, such as the low level of enterprise management, the lack of independent intellectual property rights. “Corporate duplicate construction and on-line wind power generation is currently the biggest challenges facing the industry.”

As at the end of the year, China’s total wind power generating capacity in proportion less than 0.4%. Peng-Fei Shi stressed that the current China’s wind energy industry is not surplus, the surplus is a wind machine manufacturing enterprises.

Shi Pengfei, told reporters, “Now companies are able to produce machine 80, if each of 50 company MW manufacturing capacity to calculation, the annual production capacity is 40 million kilowatts, but China’s current market is only 10 million kilowatts of capacity. the next few years, the market annual growth up to 3000 MW of excess production capacity significantly. The installed capacity in China in recent years, growth is too fast, almost every year are growing at a rate of 100%, limiting capacity is inevitable OK. ”

Now countries have begun to strictly limit the wind energy equipment manufacturing enterprises approval and access, Shi Pengfei that this is a good thing for the industry, although some lack of competitiveness of enterprises may thus eliminated from the market.

“Now everyone is concerned about the capacity problem, because production has gone up, the market has shifted from a seller’s buyer’s market, and now the focus of power enterprises, focus on product quality.”

“This is tantamount to Jiugei higher demands put forward by enterprises, companies begin to adapt to a certain area of the wind conditions, depending on the environment has to adjust their own products, rather than copy the European product standards, the original mode of production is already facing difficulties . ”

To be able to survive this round of competition in the enterprise, Peng-Fei Shi told reporters, “That is the real strength of the conservative estimate of only a small part of survival. This contradiction is resolved, China’s wind power equipment manufacturing industry in order to embark on the sound development of the road. ”

In the equipment manufacturing business survival and development issues, the Peng-Fei Shi also suggested that strong enterprises should focus on the international. “At the internal capacity of a substantial increase in the short term can not be the case, companies going out on the one hand can release capacity on the other hand can also invest in mergers and acquisitions by foreign advanced technology.”

American Wind Energy Association, the latest data show that the third quarter of 2009, the U.S. added 1.649 million kilowatts of wind turbines installed capacity, which makes this year’s total of new capacity of more than 5.8 million kilowatts.

Investment Advisor in the latest release of “2009-2012 China Wind Power Equipment Industry Analysis and Forecast of Investment Report” shows the first half of 2009 the United States new wind turbines installed capacity of ultra-four million kilowatts in the first quarter the U.S. added wind power installed capacity of 2.836 million kilowatts.

Investment Advisor in the energy industry chief researcher Jiang Qian pointed out that this new wind generators installed capacity of more than 5.8 million kilowatts, along with cut-off by the end of 2008 the United States already 25.17 million kilowatts of wind power installed capacity, that cut-off in 2009 by the end of September, the U.S. wind power installed capacity has exceeded 30 million kilowatts.

Jiang Qian pointed out that the United States Barack Obama repeatedly after administration introduced new policies to support wind power generator and other new energy industries. For example, February 17, 2009 Obama signed the “2009 U.S. recovery and re-investment Act” to the current challenging economic situation, through the next two years, the tax cuts, as well as for energy, health care, infrastructure and education in key areas such as hundreds of billions of dollars in investment, as soon as possible to create many job opportunities. Soon after, the U.S. Department of Energy (DOE) announced plans to revive and re-investment Act to provide 93 million U.S. dollars to support wind power development. These are rapidly expanding U.S. wind power industry, a major driving force.

Jiang Qian also expects 2009 should only be a transitional period is expected that with the gradual improvement in the U.S. economy next year, coupled with a new energy policy is now gradually pulling effect, the U.S. wind power industry will still maintain a relatively fast pace of development.

While the investment consultancy, research director Zhang Yan-lin, pointed out that since the financial crisis, including China, the global emerging markets for new energy industries, increasing emphasis, while the new energy development as a traditional great power, the United States of course, unwilling to lag behind in this regard other countries, this is Obama’s new energy industry, the Government will rise to an unprecedented high level of the main reasons. In addition, the growing number of countries involved inwindmill the process of promotion of new energy to not only the development of the industry will play a tremendous role in promoting, but also an effective global response to climate change will play an important role.
