Wind Turbines Manufacturer in China

Seeing huge rotor blades slash the sky in Germany has become commonplace over the last 20 years, as wind turbines have multiplied across the countryside.

But as the country races to meet European Union renewable energy targets, companies are not only under pressure to meet the time constraints of the EU’s Energy Roadmap 2050 – which highlights wind energy as a prominent future power source – they are also running out of room to expand on German soil.

Meanwhile, the US is pursuing its own renewable energy goals – a US Department of Energy report published in 2008 suggests covering 20 percent of American power needs with wind turbines by 2030. And German experience in the wind energy sector will be an important component for the United States, according to Michael Blank, vice-president of the German-American chamber of commerce.

“I think what’s good for Europe is also good for the US,” Blank said.

The United States is also good for German industry in terms of potential wind power far outstripping that of Europe.

An independent intellectual property rights, the maximum power of 2.5MW high-speed permanent magnet synchronous wind turbine in the company’s success off the assembly line. Successful development of the generator, marking the Chinese companies already have their own R & D with international advanced level high-speed permanent magnet synchronous wind turbine capacity.

Second Five-Year period, China’s wind power installed capacity of the proportion of total generating capacity will further increase, for the grid security considerations, the small wind turbine must be in the “low voltage ride through” under the protection of “Sailing with wind.” According to the National Energy Research Institute said the person, land-based wind power by 2020 the cost of coal will be flat, then wind power will be gradually out of state subsidies, reduce the cost of a wind power industry is facing the future development of the new “bottleneck.”

South propaganda minister Zhu Jianfei motor vehicle, told this reporter that the generator and the direct drive permanent magnet synchronous wind turbine generator compared to greatly reduce the volume, less weight, in particular, greatly reducing the amount of magnet, rare earth prices remain high in today, the product cost advantages become more prominent, with good market prospects. Meanwhile, the generators with high efficiency, small size, compact, low cost, high reliability, low maintenance and many other advantages, the use of full-power converter control, the unit has good low-voltage ride through performance.

Reuters quoted government data showed that China power generation increased at the slowest pace in 10 months in November, as demand momentum waned along with slowing wind generator industrial output in the world’s second-largest economy.

Slowing demand, along with recent windmill power price hikes and coal price caps, suggest a developing power shortage in the winter season could be less severe than anticipated.

The National Bureau of Statistics said electricity output increased 8.5%YoY to 371.3 billion kilowatt-hours last month or 12.38 billion kilowatt hours per day. Daily generation picked up from October when demand was at a seasonal trough between the summer and winter peaks.

For the first 11 months, power output gained 12%YoY to 4.19 trillion kilowatt-hours, higher than the total for 2010. By sources, output from coal-fired wind  power generators stations increased 9% on year the first single-digit growth since February while generation from hydropower plants staged its first increase in five months, gaining 6.3%YOy.

Last month’s output from nuclear power stations declined 6.7%.

In a vast prairie to the north of Hohhot, the capital city of north China’s Inner Mongolia Autonomous Region, hundreds of wind turbines stand like a vast, unbroken forest.

The turbines have created both opportunities and problems for the region’s power companies.

“I long for wind, but I also fear wind,” says Su Changyou, a manager of a wind farm located in Inner Mongolia’s Siziwang Banner (County).

“During high winds, my wind turbines will rotate in full gear, which means higher profits. But sometimes, my telephone rings with calls from power grid controllers ordering us to limit our power generation,” says Su.

Ever since Su’s wind farm was connected to China’s power grid last May, only about 60 percent of the farm’s turbines have been in operation. The rest of the small wind  turbines must remain idle to avoid overloading the grid.

Qi Laisheng, general manager of the Inner Mongolia subsidiary of Longyuan Power, China’s largest wind farm operator, says “these things happen all the time here. About a quarter of the turbines on my wind farm have to remain idle, even on the windiest days.”

Grid access has become a nightmare for Inner Mongolia’s burgeoning wind power industry. Wind farms in the region have a total installed power capacity of 6.5 gigawatts (GW), the most of any region in China.

China generates nearly 40 million kilowatts of electricty through wind power generators and plans to double the capacity in three years, a government agency said.

The State Electricity Regulatory Commission said wind-power generation in the first 10 months of this year rose 57 percent over the same period of last year and accounted for 1.5 percent of the nation’s total electricity output, Xinhua reported.

By the end of August, 486 wind-power stations were in operation across the country, generating 39.24 million kilowatts of electricity, the report said.

The commission estimated China has exploitable wind generators resources equaling 2.38 billion kilowatts on land and about 200 million kilowatts offshore.

With the monkey stone last October 33 wind turbines and wind power generation, rural development taking the strong pace of the wind power industry, to create two-one million kilowatts of wind power park planning, is being steadily implemented. Up to now, the monkey has a total wind power generation stone 145 million degrees.

Earlier this year, the suburbs under the jurisdiction of the wind resource distribution, proposed to build two-one million kilowatts of wind power park planning, better in the wind energy resources in the southern foothills of the northern plains and planning out the 24 wind farms with a total installed capacity of about 2 million kilowatts. Of which: in the southern foothills of the 20 planned wind farm installed capacity of 1 million kilowatts; the northern plains of four wind farms planned installed capacity of about 100 million kilowatts.

Eagle’s Nest Resources approved wind farm project has been made​​, and on April 8, construction, total investment 420 million yuan, the total installed capacity of 49.5MW, stand-alone installation of 33 sets of 1.5MW wind turbine generator capacity, supporting the construction of a 110KV booster station , 2km transmission lines, etc. Currently, the main booster station have been completed; transmission line changes have been completed; has completed 8 of the fan base does not involve forest lifting platform and approach flight path of construction, has now completed 4 typhoon hoisting machine, and the remaining four are for lifting work. Plan does not involve forest land before the end of the eight wind turbines to achieve grid.

Currently, the suburbs have made Lutiao wind power projects with a total installed capacity has reached 364.5MW. Huadian Sifeng total installed capacity of wind farm area 142.5MW project, Provincial Development and Reform Commission has made Lutiao. An abundance of wind power installed capacity of Huadian four 50,000 kilowatts, now for the grid connection procedures and some supporting documentation, and strive to obtain the grid before the end of examination and approval procedures. South wind to Sanjiang area total installed capacity of 222MW wind farm project, Provincial Development and Reform Commission has made Lutiao. Sanjiang wind energy has been developed in cooperation with Hafei Group South to regional wind power generators projects. A South to (Cheung Shun), the first Pandaoling (large to) wind farm installed capacity of 10 million kilowatts, is currently supporting elements required before approval is complete, now for grid access approvals, and strive to obtain the grid before the end of the approval procedures and feasibility assessment.

Currently, the main push of the world wind farms are often relatively large, the use of wind turbines is on the ground, take a lot of land. Although these farms are often built on wasteland, desert and sea, but on the ecological environment or have a negative impact. Compared with the ground wind turbines, air bags take up almost no extra generators of the land, so the high cost of land more suitable for installation in the roof of city high-rise buildings, local use of high-altitude wind power, erection of transmission lines can reduce the amount of remote to avoid the remote network transmission energy loss, to ease the city’s use of electricity shortage.

Of course, easy to move the generator based on the characteristics of air bags, it is particularly suitable for those who need temporary electricity sector and region. For example, the field of scientific expeditions and expedition can carry a balloon-powered generator for the camp; for maneuver forces, the air bag’s benefits are obvious generator. Temporary power for the disaster, this easy to install airbag wind generators to solve immediate problems. For those hard to reach remote areas of the grid, the generator can also find their balloon

In the 400-foot-plus wind turbines that a wind energy company wants to build on his tree farm on Maryland’s Eastern Shore, Hall Coons sees a chance at a steady stream of income – and an opportunity to untether his economic fortunes from the ups and downs of the lumber market.
But to the radar system at the Navy base across the Chesapeake Bay, the spinning blades of the towering pylons would look like aircraft – and interfere with the test range where the Navy studies how its planes appear to enemy radar, military officials say.
Plans to harness the winds that blow small wind turbines across the Eastern Shore for cheap, clean, renewable energy are arousing concern at Naval Air Station Patuxent River. And while the Defense Department does not have the authority to stop a project that interferes with the Navy’s tests, officials say the Pentagon could use its considerable influence to discourage or scale back wind farm development.

The construction of wind farms at sea have certain comparative disadvantage in the submarine base and the establishment of wind turbines are expensive to lay submarine cables, and high maintenance costs, resulting in offshore wind farm construction and operation costs are not higher than onshore wind farm less so, most of the offshore wind farm by private companies or public agencies have, instead of taking co-ownership structure of the way operations.

Kroger said that in order to reduce the cost of offshore wind farms to achieve economies of scale, the best way to build a number of operational wind turbines continuous operation at sea. To this end, the East energy company in the west coast of Jutland in Denmark established an installed capacity of 160 MW of large-scale offshore wind farm. There is also a very large installed capacity of 400 MW offshore wind farm under construction, the wind farm will have 111 wind turbines in Denmark for 400 000 family power.

Kroger that was built on land such a large-scale wind farm is almost impossible, so offshore wind farm has a unique advantage of scale through large-scale overall planning and operation of offshore wind farms and land costs can be reduced toupper hand in the same field level.

Reasonable price to support the development of small wind turbines industry

Currently, about 17% of Denmark’s energy from wind 、 sustainable bio-energy and solar energy. Danish government’s plan is that by 2020, wind power reached 50% of total electricity generation by 2050 completely free of fossil fuelsdependence construction land 、 offshore wind farm is one of the ways to achieve these goals, but to maintain the sustainable development of wind power industry to improve competitiveness, the need for green energy to develop a reasonable pricing policy.

In order to support sustainable energy projects, the Danish government to pay the price of wind power is slightly higher than the market price. In this regard, Professor Ka Yueer, high prices will not only improve the overall energy prices, will be to bring a good wind turbine generator impression that “wind energy is good, but expensive.”

In this regard, the Danish Climate and Energy Committee Xijia De said, we must consider not only economic, but also to take into account environmental and social benefits. With the business philosophy of innovation and technology, wind power will be increasingly competitive, we used funds to support wind power development and investment will be less and less.

Wind power into a mature small wind turbines manufacturing industry brings a big plus, wind power is the “bottleneck” problem will be solved.

Currently, wind turbine manufacturers and operators are stepping up to the wind turbine for low-voltage ride-through of the upgrade, Sinovel Chairman and CEO Han Junliang recently in the “2011 Beijing International Wind Energy Conference and Exhibition Entrepreneurs Forum”, said Rui Hua Wind power will be completed before the first quarter of 2012, nearly 7,000 WTG on the overall upgrading work.

The construction of national policies on the grid circuit, active consumer of wind power has also made a request. National Energy Board new and renewable energy Shi Lishan, deputy director of the wind show that the Chinese government’s current policy for the wind power industry, mainly in the support price of wind power construction, in the formulation of development objectives, policies and related tax compulsory consumption quota policies should be improved.

In addition, “China Business (blog, microblogging),” Reporters from the wind power industry was informed by the researchers, a large-scale wind power grid there is no technical limitations in the acceptance of wind power has great potential.

As of the end of 2010, West Inner Mongolia grid access wind capacity amounted to 6.3 million kW, accounting for a total installed power capacity of 16.4%, accounting for the largest power generation capacity of 32%, accounting for 38% of the maximum power load. March 17, 2011, wind power capacity reached 20.9%, and to ensure the security and stability of the grid.

These facts have proved that a large-scale wind power is feasible.

Specific solutions are implemented. “Twelve Five” period, the wind power industry from “building a large base, into the bulk power system” to “both centralized and distributed,” change, but also to develop offshore wind power. The distributed wind power and offshore wind power development means that future wind power development and the development of the national grid will be more matches, because these areas will be more close to the coastal areas of large power gap, wind power will greatly reduce the pressure small.

From the Grid perspective, the national power grid is building a strong intelligence network at the same time, Jiuquan 750 kV grid and national grid, “four vertical and four horizontal” long-distance wind generators transmission channel has a large open building, which will fundamentally solve the wind power is difficult, the difficult problem of transportation.
