Wind Turbines Manufacturer in China

Currently, coal-fired power plants account for about 75 percent of electricity in China. Generating electricity from wind has proven useful in reducing emissions of carbon dioxide and other greenhouse gases as well as in curbing global warming. The World Energy Council estimated that every 1 million kilowatts of wind-generated electricity will save about 600 tons of carbon dioxide emissions on average.

China has great advantages for the development of wind power generation. China is a country with a vast territory and abundant wind energy resources. The total wind power of China is more than 3 billion kilowatts, ranking first in the world. In addition, the average wind speeds of most places of China are more than 3 meters per second, and the best wind speed for wind power generation is between 3 and 25 meters per second. Of these places, the northeastern region, northwestern region, southwestern plateau, Inner Mongolia, coastal regions and islands have especially-qualified wind speeds for wind power generation and huge potentials for the development of the industry.
Currently, wind generator has become the leader of Chinese green energy industries, but some problems have also emerged successively.

Lin said frankly that power grid integration is still the largest difficulty that blocks the development of China’s wind power generation.

It is difficult to control the stability of wind power when integrating it to the grid, which has very high demand both on the stability and long-distance conveyance of wind power. Statistics show that 10 percent of wind power is wasted because wind power is poorly integrated into the grid, and the grid cannot bear the load.

Wind power will continue to lead the development of China’s green energy in the next few years. Statistics from the National Energy Administration show that by 2015, China’s wind power installed capacity will reach 100 million kilowatts and can save about 80 million tons of standard coal when the annual energy output exceeds 200 billion kilowatt-hours, and wind power as a proportion of total energy will increase from nearly 1 percent in 2010 to about 2 percent.

Tianjin’s first wind farm – Binhai New Area Dashentang wind farm, line 7, live operation. After 240 hours after the trial run, in mid-September the access network in Tianjin, Binhai New Area to provide for an annual 52.13 million kwh of green power.
Reporters at the scene saw 7, 13 sets of 80 meters as the unit like a large white windmill along the coastline of the Bohai Sea in order of priority, very spectacular. Dashentang wind farm project 13 units with a total installed capacity of 2.6 million kilowatts. The wind turbine project has created three “highest in the country”: One is the domestic roadbed installation run the single largest capacity, the unit capacity of 0.2 million kilowatts; the second is the longest diameter of the blade diameter of 93 meters; Third scientific and technological content, with completely independent intellectual property rights.
According to reports, a large wind farm is Shentang Tianjin’s first wind power project, energy consumption is far lower than the traditional indicators of coal-fired units. To consume 355 grams of standard coal power generation as one kwh conversion standard, large wind farm Shentang annual savings of 19,000 tons of standard coal. Meanwhile, the annual saving 30,400 tons, 60,000 tons of carbon dioxide emissions, 88 tons of nitrogen oxides, soot 10.4 tons, 39.2 tons of sulfur dioxide, to promote energy conservation in Tianjin, Tianjin to meet the new eco- City of renewable energy utilization rate greater than 20% of the requirements has created important conditions.
Dashentang wind farm project is the first case the use of advanced distributed access wind farm, from the power terminal to the access network, the distance is only 8.1 km, how much fat, how much, less power loss, maximum reduce the loss of power transmission link, significantly improve energy efficiency and input power quality.
Dashentang or domestic wind power project construction in the eight first seismic intensity of the wind farm area, for areas with harsh geological conditions, the accumulation of experience in wind farm construction. State Grid Power Company of Tianjin, although wind turbines is unstable, but because of Tianjin Power Company in advance of the technical studies, wind farm design, construction, access to relevant technical processes are carried out to prepare during the test run will not Binhai New Area affect network security, stability, and formally put into operation after the Tianjin Binhai New Area and will not affect the main power grid network security.
Tianjin has become China’s wind power equipment manufacturing base. Land-based wind energy resources in Tianjin Binhai New Area are mainly concentrated in coastal areas, high wind speed time to focus in March to May, followed by February and June, the time is relatively low in August and September.

China’ s largest wind power developer, signed a share purchase agreement with a Canadian power company on Wednesday, marking the company’s first foray into the global wind power market.

Under the agreement, Longyuan Canada Renewables Ltd., a subsidiary of Longyuan Power, will purchase equity shares of a 100-megawatt (MW) wind farm that is being built by Farm Owned Power (Melancthon) Ltd., a Canadian power company based in Ontario, Canada.

Industry insiders say the project will be completed in about two years, but did not give a precise starting time for the project.

When completed, the project will be able to supply electric power for 30,000 households, Longyuan said.

The deal marks the first time for a Chinese state-owned power company to invest in a wind power project located overseas. Longyuan kicked off its efforts to purchase the equity shares in November 2010.

Xie Changjun, general manager of Longyuan, said Canada small wind turbines boasts rich wind power resources and excellent supporting policies for its wind industry, which have helped to create an ideal investment and operation environment for wind farms.

According to Denmark-based consultancy company BTM Consult, Canada had the largest amount of installed wind power capacity in North America by the end of 2010, just after the United States. According to its provincial wind power development plans, Canada will have 12 gigawatts (GW) of installed wind power capacity by 2016.

Longyuan’s wind farms totalled 6.56 GW of installed wind power capacity by the end of 2010, the single largest amount in Asia and the third-largest in the world, according to a BTM report.

Longyuan has been vigorously exploring the global renewable energy market in recent years, establishing offices in South Africa, the United States, Canada and Europe.

Longyuan said it has made substantial progress in establishing wind power generators projects in South Africa, in addition to its advances in Canada.

The end of 2010, China’s total wind power installed capacity reached 44.73 million kilowatts, more than the United States ranked first in the world. At the same time, offshore wind has started. Last February, China’s first offshore wind farm demonstration project, is Asia’s first large-scale offshore wind farm – Shanghai Donghai Bridge, the electric field of 10 million Wahe Shangfeng 34 units installed, and then in June to achieve grid , to provide electricity for 40 million families. In addition, the domestic first offshore wind power generators concession projects in the same year work started in May. Was vividly in 2010 compared to offshore wind power development in China the first year.

China Wind Energy Renewable Resources Institute, Qin Haiyan, secretary general that the reason for China’s great attention to offshore homemade wind generator , not as many European countries because of depleted land resources development, on the contrary, China’s onshore wind resources, there is great development of space. To develop offshore wind power, more from the natural resources, climate change, economic and other aspects into account results.

Potential

Although offshore wind power generation in equipment installation, transportation, maintenance and other than the existence of onshore wind power generation more difficult, but there are still a lot of China’s development benefits: for example, 5-25 m depth within the sea, 50 m height wind can be installed capacity of about 200 million kilowatts; 5-50 m depth, 70 meters high installed capacity of wind turbines can be about 500 million kilowatts. Traditional offshore wind power near the load center, to facilitate power-consumptive, can reduce long-distance transmission troubles.

China Wind Energy Renewable Resources Institute, said Commission Vice-Chairman Shi Pengfei, 2015, China’s offshore wind power installed capacity will reach 500 million kilowatts and even than expected, but compared to last year, more than 900 million kilowatts of electricity installed capacity, the ratio still very small, expect offshore wind to ease the current shortage is not the reality, the exploration of offshore wind is more for energy conservation, climate change considerations.

The worker, standing inside a section of what will eventually be a wind turbine, looks up as a piece of equipment on a rope is gently lowered inside through a hole.

Wearing an orange helmet, a grey T-shirt and once-white gloves that have long since turned grey, he manoeuvres the machinery as a colleague outside reaches in to help.

He works frantically inside the huge circular frameto which vast blades will be attached.

Outside this warehouse-style factory building in Baoding, a city a couple of hours south-west of Beijing that is home to 170 green-technology companies, are the 40-metre-long small wind turbine blades. They appear elegantly sculpted as they lie side by side in countless rows.

Nearby, protected from the elements by cloth for wind turbine generator coverings, are scores of nacelles, the frameworks that contain all the power-generating parts of the turbine.

It is perhaps no wonder that this facility, belonging to the state-owned Guodian United Power Technology, is churning out wind turbines by the dozen.The market for them in China is booming.

Last year, the country installed almost 19 gigawatts of new wind energy capacity, taking its total to 45 gigawatts, the largest in the world.

Companies such as Guodian, which supplies all the components except the huge towers on which the turbines sit, have boosted production to capitalise on the vast investment in the sector.

Guodian produced 100 wind turbines in 2008, 600 in 2009 and 850 last year, all for domestic use. This year, thanks to the opening of new facilities, the company’s annual production capacity will increase to 2,000 turbines, says Wang Hongbin, the company’s deputy general manager.

China will increase its offshore wind power installed capacity to 5 gigawatts (GW) by 2015 and 30GW by 2020, the National Energy Administration said Wednesday.

The public tender for the second round of offshore wind power generators concession projects with a total installed capacity of 1.5GW to 2GW will be completed during the first half of 2012, the administration said at a meeting held in the city of Nantong, Jiangsu province.

China faces a 30GW power shortfall this summer, according to data from the China Electricity Council.

Liu said the country should expedite the establishment of an advanced and fully-equipped offshore wind power industry to boost its large-scale development.

In June 2010, Shanghai’s East Sea Bridge’s 100MW offshore wind turbine generator farm project was completed. It is currently the only offshore wind farm that has been put into operation outside of Europe.

June 22 to 24, the Eighth Asian Wind Energy Conference and International Wind Energy Exhibition held in Beijing. In the domestic wind power industry generally “sluggish” in contrast, the lifting of Dalian Heavy Industry Group as a “leader” of Dalian wind power equipment wind turbines manufacturers collective appearance of the exceptionally bright. Heavy lifting on display 6 MW small wind turbine is the core component of goodwill for the exhibition “BMW”, leading the trend of large-scale wind turbine. After years of industrial restructuring, DHI DCW Group has become the largest megawatt wind power base of the core components of development, Dalian wind power equipment industry chain has been basically formed.

Dalian wind power equipment business after years of “Revival” has mastered the core technology to mass production, stable performance, high-quality products, revealing a mature temperament.

Reporters from the show forum that China’s wind energy industry started late, at least 20 years, and the pace of development has forced the world’s attention. However, the rapid development of the drawbacks is the core component of wind power equipment, mostly hovered in the low end. After several years of domestic wind turbines industry, “Great Leap Forward” development, entered a “Ebb Tide” period of adjustment. DHI DCW Group from 2004 MW of wind power generation equipment developed core components by absorption and innovation, has become the largest MW wind power base of the core components of development. In 2010, wind power product sales revenue of 8.5 billion, the Group’s total sales revenue of more than 50%. U.S. GE, Mitsubishi and other world famous companies have for many years, with India now has two well-known enterprises to establish a partnership fan, the international trend has emerged.

The county signed a total investment of 15 billion yuan 30 scale of 1.5 million kilowatts of wind power projects, to the end of installed capacity of 400,000 kilowatts, the province’s total installed capacity of close to 2010, the province’s total installed capacity in 2011 of 50.6%.

Shenchi conscientiously implement the Party “35″ spirit of excellence environment, change the wind to treasure, so that this new wind energy industry in the county to bear fruit. Shanxi International Energy Group Ltd., a building, two wind farms have been grid, yellow mother of 6 Wind Farm project progressed smoothly to the end of the county’s wind power installed capacity reached 40 million kilowatts, close to 2010 the province’s total installed capacity of 440,000 kilowatts, accounting for 2011, the province’s total capacity of 790,000 kilowatts installed capacity of 50.6%, wind power industry cluster shape. Expected to become the province’s largest wind power base.

Strom County is located in northwest Shanxi Loess Plateau, with an average elevation of 1,600 meters, wind resources, known as the “year of a wind blown from the spring and winter,” saying the small wind turbines was Strom’s disadvantage, but world wide shift in thinking, Along with the development of new clean energy, wind has become the Strom and the country inland Shanxi Province, the better wind resources in one of the areas to shenchi brought a rare opportunity for development. In recent years, the wind turbines county emancipate the mind, do not break shenchi industrial mindset and establish a clean development, cycle development, green development concept, to seize the opportunity, environmental excellence, the introduction of large items, change the wind generator to treasure, to create new clean energy demonstration base. Currently the county has signed a total investment of 15 billion yuan 30 the total size of 1.5 million kilowatts of wind power projects. To speed up wind power projects, the county environmental excellence, improve the style, enhanced services, law enforcement standard, open procedures, the implementation of sun-government, strengthen the comprehensive management of social order, and build a peaceful Strom, maintain social stability, to create a safe, honest , civilization, and the efficiency of Strom. Good investment environment, promote the rapid development of wind power projects. Which by the International Energy Group Ltd. Shanxi investment and construction scale of 99,000 kilowatts, generating capacity of 240 million degrees in one or two wind farm was in June 2010 for power generation; investment by the China Long Yuan Electric Group, the construction of female yellow Wind farm investment 397 million yuan has been completed, by the end of the grid; South Hua Wind Farm project has been started, and strive to build during the year; following the Yangshan wind farm, Wind Farm wenjia Huaneng Group, Taipingzhuang Itai wind farm, wind farms will be started soon Yijing, is expected to completed by the end. Strive to “Twelve Five” “Thirteen Five” early, has signed 30 1.5 million kilowatts of wind power projects are completed, will become the inland areas will Strom wind power industry, one of the largest counties. For the healthy development of the wind power generators industry, rapid development, Strom County has proposed the establishment of new energy office, coordinating services, wind power companies, while actively apply green energy county, the current material has been prepared by the National Energy Board Energy, will report to the National Energy Bureau, the county as early as possible to the county as a national green energy.

Wind power in order to achieve comprehensive, coordinated and sustainable development, we must actively make use of scientific and technological progress. China Renewable Energy Association secretary general of the Qin Haiyan that “innovation is the enterprise, industry and even a source of national competitiveness, we must cherish the huge opportunities brought by the windmill power market, through increased research investment, the establishment of national public R & D and testing platform to accelerate the development of qualified personnel and other measures to constantly improve the technology innovation system, promote the power of the wind power technology forward. ”

Scientific and technological progress to increase wind power generator capacity. According to the latest information on wind resource assessment, land-based wind resources in China’s power generation potential of up to 2.38 billion kilowatts installed capacity, installed capacity of offshore wind power resources of up to 2 million kilowatts. But subject to environmental, traffic, climate, minerals, and other factors, the actual wind resources can be developed much less than its potential capacity. Therefore, the development and utilization of wind power must establish the concept of economical use of wind resources.

Take advantage of wind power development in scientific and technological progress, improve the power grid on the acceptance of wind power capacity. Full use of wind turbine design and manufacturing technology to improve the capacity of wind energy capture, reduce unit failure rate, unit converter and optimized control strategy pitch system to achieve maximum use of wind energy, and omit or simplify the gearbox with direct drive, semi-direct Flooding to reduce the gear box failure on the impact of fan operation.

Micro-site wind resource assessment and technology is very important. Construction of wind power in the early stage of full use of GPS satellite positioning technology combined with wind measurement data to achieve operation in the computer model, distributed computing regional wind turbines resources, wind farm power generation calculation, calculation of wind farm efficiency cloth and so on, integrated consider different terrain conditions, surface roughness and obstacles, each wind turbine wake effects on the distribution of wind resources. Based on the current level of wind turbine manufacturing, technology maturity and price, combined with characteristics of wind farms wind conditions, level of security requirements, on-site transport conditions, geological structure condition and hoisting conditions, to determine the optimal range of unit capacity , unit type, so choose the best development program to achieve maximum use of wind energy.

Recently, Google announced that spend $55 million in the United States for the southern California Alta wind power projects investment, which means Google the Internet giant is organized into electricity market in ways. Since Google CEO larry page for clean energy is having strong interest, asserting that clean energy is the future development direction.

The investment Alta wind power projects under construction could become the nation’s largest wind farm, its power-generation capacity strong is enough to supply 450,000 families use Google send electricity. Along with the investment in clean energy page, including total investment over field has four million dollars.

With the Google teamed up with investment and citigroup also earlier, plus $5,500 million investment to the Google input, California, project investment 1.1 billion wind. The wind turbines manufacturers farm produce 15 million watts of electricity, enough to meet the 45 million households, the future will be in demand in the nation’s largest wind project. Operation, Google said in a statement that Google and citigroup will buy this project, and its back to tara root, according to long-term agreement by the latter management and operation is the power station.

In addition to wind farm construction, Google end also announced 50 million investment windmill generator project, a sea power grids for 350 miles of transmission network, will the future of Atlantic conveyor to American coast’s largest wind energy consumption market.

As early as November 2007, Google created the “big energy development strategy”, plan to build such as wind, solar and geothermal wind power generation systems. In addition to Google, Microsoft has revealed that tap into the wind, because these power consumption of industry data center server the practice of wind power, huge, accord with their lower costs, reduce power consumption on the environmental impact of strategy. But Google is not going to put these clean energy use in your own any operation link, but plan will these energy sold to local power grid corporation, such as A lta wind power is sold to California, so as to achieve renewable permit, and then it using this marketable license, to offset their operations of the carbon emissions.
