It has a beautiful name is winter and spring pastures. Every May, the Gesang Hua will open grassland was particularly brilliant. Tibetan nomads hospitality here, but because of no electricity, and they still live sunrise and sundown life. In the absence of electricity, seriously hampered the development of local economy, many young people have work outside the home, do not want to go back to this piece of barren land.

A

August 2008, one from the Dulan County, Qinghai Province Development and Reform Commission’s “I hope to have research institutions in the development of small wind turbine suitable for plateau” of online information, caused thousands of miles in the assembly of a research institute in Sichuan researchers attention.

The Institute is located deep in Western North Mountain, the largest low-speed wind generators tunnel in Asia group. It is not only the cradle of aircraft is also the earliest development and use of wind energy to carry out scientific research institutions. 30 years, the institute has carried out in cooperation with many domestic wind turbines  manufacturers of wind turbine development, has completed a national “Seventh Five,” “Eighth Five-Year” and the “Ninth Five-Year” Aerodynamics of wind turbines and wind turbine aerodynamic design package research projects; use of wind tunnel nearly 10 kinds of domestic small wind machine for the completion of performance testing and aerodynamic performance evaluation; the Institute also developed six kinds of independent small-scale wind turbine prototype.

Coupled with long hours at high altitude sunshine, sand large wind turbine production materials are fast aging, a series of questions put by the researchers in the front. Open bow arrows without looking back. The organization of the set of all the wise crack research, the institutions created and the aerodynamic design of wind, Wind tunnel tests related to the theoretical calculation as well as product testing, field-site links, one by one scientific proof.

home wind turbines blade is the most important one of the key components, which directly affects the exterior design of wind turbine on the wind energy absorption efficiency. In order to improve the utilization of wind energy function, they carefully analyze the local climate and environmental characteristics of the wind turbine blade for a special design and processing, so that leaves the largest wind energy utilization coefficient of 0.480, starting wind speed less than 3m / s. This 800W wind turbine developed by the same wind turbine to increase power generation compared to 48W, power generation increased to 848W. When the sample machine developed by, the scientific research staff excitedly, a new reality problems are placed in front of them. How the research results into the final product to Dulan County, Qinghai Province, the local people? After many test, the the Institute and Green Haifanuoge Energy Technology Co., Ltd. reached an agreement and decided to Dulan County, Qinghai Province, a remote village as a product testing pastoral land, free of charge to local people. A typical wind turbine market price in 8000 yuan, while the per capita income of local people to reach 3, 4000 yuan. Free installation of wind turbines, which border pastoralists, the really great news.

April 2010, when the want to free installation of home wind generators Dulan County, Qinghai Province, the news reached the town of iron were added Kui village, the village excitement. When carrying wind turbine car to get there, a lot of early Tibetan people waiting there. Some people still come from far away. That scene just as festive as barley wine, Hada, every face was beaming with smiles. Farmers say, “Great, look forward to for so many years, we finally have here, dead. From under the child can do homework in the light of.”

Although the installation process is simple, but far away from pastoral households, often only one day to install 12. A total of 40 people in a village, the installation was a whole month. When installed on the local Tibetan people Suk home, he excitedly said: “Before, no electricity, do have to rely on manpower. Now have electricity, we can buy a machine to cut wool shearing, so good and fast. Moreover, after the money, I still want to buy a TV, do not go out, you can know a lot of things out. ”

August 9, 2010, represented by the local government with the power ceremony was held in the village. Herders have to barley wine, Hadad dedicated researchers. See the wind turbine to the local changes caused by the heart, the researchers heartily rejoice. Next, the wind turbine will be used widely.

Slow off the line and crippled at high speeds, the turbines are effective at generating electricity only within a sweet spot of moderate wind speeds.

Scientists from Purdue University want to change this by creating intelligent vertical wind turbines that shape-shift with the wind. These smart wind turbines generators would help maximize the amount of electricity generated by wind power while ensuring longer life spans for wind turbines.

“We eventually want to put aerolons or actuators on the blades to quickly adapt how the blade flies through the air,” said Jon White of Purdue University, an engineer working on the project.

“One second you will have one kind of blade, and then the next second it will change into another shape, depending on the wind speed,” said White.

White and his colleagues recently installed accelerometers along three 30- foot-long blades of a research turbine near Amarillo, Tx.

Made of balsa wood and fiber glass, the blades are right on the border between personal and commercial-sized wind turbines, said White.

The accelerometers measure how the blades subtly twist and turn as they cut through the air. In the first stage of their research, the Purdue scientists are measuring for blade fatigue and efficiency in an effort to design future turbine blades that last beyond the usual 20 years.

Once they have gathered enough data, the team plans to link the data from the accelerometers to mechanical actuators or aerelons, the flat panels on airplanes that help direct airflow, on the ends of the blades and to a control panel.

Traditionally, wind generators blades are fixed. They have one fixed shape optimized to perform during moderate wind speeds. During low wind speeds the blade is too narrow for the wind to push the blade around efficiently. High wind speeds, which could generate the most power, push the blades too quickly, threatening to break the blade and can force operators to limit the speed and energy production.

Linking the accelerometers to the actuators would enable the turbine blade to quickly change shape and adapt to whatever kind of wind conditions are present to optimize the amount of electricity they can produce and extend their life span as long as possible.

Wind turbines are already pretty efficient, says Jose Zayas of Sandia National Laboratories’ Wind Energy Technology Department. Intelligent wind turbines could help generate single digit increases in electricity generation. Add to that the lower installation costs and a longer life span, however, and the savings will start to add up nicely.

“All of this will help reduce the cost of wind energy,” said Zayas. Even if accelerometer-equipped blades don’t physically change their shape, the increased data coming into turbine operators will help them to delicately fine tune their systems.

Smarter small wind turbines could be available in as little at three years, although it will take longer for shape-shifting turbines blades to appear.

“In the past years have seen only in the rural areas of wind power generators, did not expect Hangzhou have this stuff.” Mr. Zhou telephoned immediately to the Morning Post.

Of these two wind turbines, installed in Zhejiang Electric Power Test & Research Institute 8th floor roof of a building. 5 m tall thin poles, security with clover fan, turning slowly in the breeze. Far looked like a vertical fan.

“This wind turbine can be really small, is not home to?” Mr. Zhou would like to know how much money a sale, if the price was right to give their own pretend one.

Kaixuan Chinese family who lives in the pool also saw Aunt Lee, she said two years ago, she had a second floor Kaixuan roof, but also seen a small wind generator.

“I was specially come to ask that family, how this generator is loaded. They said that the wind generator is a subsidiary of Zhejiang University, a high-tech company, used for scientific research, priced around 2,000 yuan.” Aunt Lee said.

However, the public Hu believes that wind turbines do not really suitable for installation in residential homes. Because it needs to be installed at high levels, if every household like “Teletubbies,” like, it will affect cities.

Most people said, the most critical problem, or Hangzhou are less windy weather, little wind, usually only a gentle breeze blowing gently, hair not much electricity. Of course, Hangzhou frequent typhoons in summer, but the typhoon wind and fervent, very safe with them. So, is suitable for wind turbines along the coast in the northwest highlands and rural areas where the use of wind power, where large, relatively stable.

Electric Power Test & Research Institute Office of the Song Dynasty teachers, this is the end of two wind turbines installed last year, mainly for wind power research institute engaged in scientific research and experiments. Two days ago, started power generation, yesterday morning, made a 3 kilowatt, 100-watt light bulb for 30 hours point.

Song says that now advocates the use of clean energy, energy-saving emission reduction, wind generator sends electricity, is a typical of clean energy. Two wind turbines are connected to the following large-scale battery room, can be sent to the wind electricity, are connected into the battery to store up and put into use by the converted.

Wind turbine is currently still in experimental stage, if the trial is successful, could be the first in industry to promote the use, if the technology is mature, extended to the household is also possible.
