April 2010, when the want to free installation of wind turbine Dulan County, Qinghai Province, the news reached the town of iron were added Kui village, the village excitement. When carrying wind turbine blades 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. Local people said the small wind turbine not only bring light to them, but also brought hope for development.

Deserves attention is that there is no similar domestic and vertical wind power generator manufacturing standards, the Chinese Mechanical Engineering Society Testing Center, said future development of national standards for record of the Enterprises will field strength standard as a reference.
Ling Zhen Wang said V5.0KW home wind turbines characterized by the largest independent portable mobile power generation system, designed and produced two field strength will be low speed for home use of vertical wind power generator.
Then a generator cost? A family a few years to recover the cost? With this general home users are most concerned about questions raised by wind generators wild enthusiasm. Rui said that the current R & D V5.0KW vertical wind power generator is mainly directed against the communications industry, road transportation, electricity and fresh mountain power, field work, border design of these industries, and in the future they will focus on two production production 1KW, 1.5KW power smaller vertical wind power generator to meet the needs of the market vacancy.
According to reports, a low-power vertical-type wind turbine market position will be 3-5 million, the general villa daily consumption in the 30-50 degree / day, 3 to 5 years will be as cost recovery. A vertical-type wind turbine service life of 30 years, lower maintenance costs during the period.

Last November, days Jie Group and China State Power and the air damper joint venture power company electricity and clean wind energy in Inner Mongolia China Co., Ltd., responsible for the development of Inner Mongolia Hing’an one million kilowatts wind farm, the first phase of 49,500 kilowatts wind was Inner Mongolia Autonomous Region Development and Reform Committee approval, will and power generation.

“As a clean energy, wind power generation in the world with an average annual increase rate of 30%, China’s faster, more than 70%.” Edge Yu told reporters in the next three years, space research and development of clean wind power to 3,000 kilowatts and above wind turbine, the formation of annual production in 5 years, more than 1,000 MW of wind power generating units of the national large-scale equipment wind generator manufacturing base, 10 years ranked among the top three wind power manufacturing industry.

Regular maintenance can make devices to keep the best of the state, and to extend fan life. Regular repair and maintenance work of the main elements are: fan couplings between the bolt torque inspection (including electrical connections), the lubrication between the transmission components and various functional tests.

Fan in normal operation, each connected component of the Bolt to run in a variety of vibration of long-term effort which is very easy to loose, so in order not to loose bolts after the cause of local Shouli Bu were cut, we must regularly Bolt torque check of their conduct. In the environmental temperature is lower than -5 ℃, should make it down to the rated torque for tightening torque of 80, and after the temperature is higher than -5 ℃ review. We generally check on the fastening bolts are arranged in non-small air or wind in summer, to avoid the high power fan season.

Fans of the lubrication system mainly dilute oil lubrication (or lubrication of mineral oil) and dry oil lubricating wind turbines (or grease lubrication) in two ways. Fan gear boxes and yaw Gear Box uses a thin lubricating methods, the maintenance is of additional testing and sampling, if the test results show that the lubricant can no longer use, then wind power generator replaced. Generator parts are dry lubricated bearings, yaw bearing, yaw gear and so on. These components run as high temperature, highly degenerate, resulting in bearing wear and tear, regular maintenance must be carried out each time up to its increase. In addition, the generator bearings according to additional doses of a certain number of requests to join, not too much, to prevent too many to squeeze into the motor windings after, the motor burned out.

Regular maintenance of functional testing test key too quickly, emergency shutdown test, hydraulic system component value test, vibration test switch, twisted cable switch test. You can also set limits on the controller, some routine test values. In addition to regular maintenance other than the above three items, but also check the hydraulic oil level, small wind turbines the sensor for damage, the sensor’s power supply is reliable work, brake pads and brake disc wear and so on.
