Wind Power,Wind Turbine Manufacturer

Usually people think that wind power generator wind power solely by the decision, always wanted to buy a bigger wind turbine, which is not correct. The current to the battery charging wind turbines only, the energy stored by the battery up, people eventually use electric power, size and battery size have a closer relationship. Power depends on the size of even the size of wind, not just the size of the power head. On the mainland, a small wind turbine will be more appropriate than large. Because it is easier to drive and a small amount of wind power generation, continuous small wind, strong wind better than the moment a large supply of energy. When no wind when the wind it can also be caused by normal use of electricity, that is a 200W wind turbine generator can also be a large battery and inverter by co-use, access to 500W or 1000W and even more power out.
Use of wind generators, wind energy is pouring into our family used to the standard electricity, the savings level is obvious, a family only 20 yuan a year of electricity cost of battery fluid. Now the wind turbine performance than a few years ago a great improvement, previously used only in a few remote areas, wind generators connected directly to power a 15W light bulb, one out of a dark and often damage the bulb. And now because of technical progress, the use of advanced chargers, inverters, wind generators as a certain scientific and technological content of the small systems, and can under certain conditions, instead of the normal electricity. Mountain to the system can not be a perennial money-lights; highway signs used it to do the night lights; mountain children can study up under fluorescent lights; urban high-rise roof, wind turbine  manufacturer can also be used, which not only save but also real Green Power. Domestic wind generators, not only to prevent blackouts, but also increase the zest for life. In the tourism area, border, school, military and even behind the mountain, home wind turbine procurement is becoming a hot one. Radio enthusiasts could use their own technology in the wind power generation services for the mountain people, so that people watch television and lighting synchronized with the city, but also make their own enrichment work.

August 19, 2010 3-day Inner Mongolia, wind, solar power industry, power industry exhibition cum International Convention and Exhibition Centre in Inner Mongolia opened.

According to reports, Inner Mongolia, a vast, wind energy, solar energy resource rich wind energy resources now total reserves of about 898 million kilowatts, which can be developed using wind energy resource reserves of 1.5 million kilowatts, accounting for development and utilization of wind energy resources can be half of the total, ranking first. Wind energy resources in our region has a wide distribution, good quality, good stability, continuity of strong, non-destructive typhoons and hurricanes, high wind energy utilization features a bright future of wind power development.

Thin air at high altitude, common small-scale wind turbines there, power will be greatly reduced, the original theory of design is possible only 800W to 700W. 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. Local people said the wind turbine generators not only bring light to them, but also brought hope for development.

Tubular towers safer for maintenance personnel, because they can reach the top of the ladder inside. Grid tower is that it is cheaper.

“China’s New Energy and Industrial Development of wind energy, wind energy development prospects in the marine, offshore wind will be the future direction of China’s wind energy and the high ground.” One industry expert commented on the importance of offshore wind energy.

China’s rich reserves of offshore wind resources. According to the latest wind energy resource assessment, wind energy resources of China’s land can be used 300 million kilowatts, with the use of wind resources in coastal waters can be a total of about 10 million kilowatts, huge growth potential.

Earlier this year, according to the National Weather Service in China completed the first detailed investigation and evaluation of wind energy turbines resources, our measured 25 meters water depth of 5 meters to the line within the coastal area, 50 meters high above sea level can be installed capacity of about 200 million kilowatts.

Broad prospects for offshore wind energy renewable energy quota pressures facing the electricity giant, engaged in a fierce battle. As the east coast, especially in Jiangsu and other coastal beach and offshore wind power has developed very good condition, the major electricity companies, “Happy Valley Circle Sea” has become a trend, China Power Investment, State Power, Huadian, China Guangdong Nuclear Power, Datang, China Resources Power, Jiangsu Guoxin Group, the German Solar CCE have involved.

In May, the National Energy Board launched the first round of offshore wind power generators domestic franchise tender, no doubt first tone starting gun. Huaneng, China Guangdong Nuclear, and other large electricity giant Shenhua have already purchased the tender, and local governments, small equipment manufacturers, supporting business and so the market stakeholders are also actively awarded by which tenders are expected to release by the end of September.

Recently, the National Energy Board launched the Jiangsu Province, four offshore wind power project tendering and bidding will be completed in September this year work. The offshore wind power online pricing policy “is not the only cheap is to take” line of thinking makes the offshore wind generators has a higher than land-based wind power margins, this is central to many enterprises that offshore wind power the tremendous business opportunities.

Now, offshore wind power is becoming a new favorite in the field of wind power in China. Compared to land-based wind power, offshore windmill  power with wind energy resources are very stable and do not take up land resources, the advantages of minimal environmental impact.

Fourteenth in Xi’an, China, East and West Cooperation and Investment Trade Fair, the Shanxi Yongji Motor Company and the wind power generators  manufacturing company signed a total of 2.7 billion in wind turbine supply contract volume, it is concluded our wind generators business largest wind turbines.
CNR Yongji Electric Corporation as a commitment to build our country, “China’s first international-class” international enterprise of electric drive system, last year, the international financial crisis continued to maintain a rapid growth with sales of 2.8 billion .wind turbine generators business in which sales increased 139.8 percent over the previous year, to become new economic growth point in the company.
The industry believes that the company won the favor of key domestic and foreign customers is: carefully build quality, and constantly improve product quality.
First, a quality wage system. From July 2008, the company introduced incentive-based wage system quality. According to “Grading grade, good quality and inexpensive” principle, and gradually improve the quality of the distribution of wage income in the amount employees, the employees establish a quality product in terms of ideology is dry out, rather than the quality of testing out ideas, enhanced staff sense of quality. The same time, gradually increase the rate of parts superior product, superior product quality on the production staff groups incentives to form links with high quality components to form excellent products, machine products to achieve high quality, and finally develop the company’s quality culture characteristics . Last year, the company’s product qualification rate of 96.85%.
The reform of the lean production management. The company’s implementation of the reorganization, clean, clean, quality, safety “5S Management” and “red war” strategy to implement lean home wind turbines manufacturing concepts in production management. Production plan prepared by the sales contract, material requirements planning the production schedule by the establishment, operation plan will be detailed to the day, to improve punctuality and balanced production rate. Currently, the company implemented lean production management transformation, to produce on-site continuous improvement and staff training for the Mubiao Lean Thinking, Tuijin production site problem identification, analysis, improvement activities, and further promoting the 5S visual management, implementation of new product vertical wind turbines manufacturing the whole process of monitoring.
Third, the full implementation of the integrated management of production quality. Production tasks linked with the quality, culture and production, technical personnel establish a “no quality of the production schedule is equal to zero” quality management concept; established a system of accountability for the quality of leading cadres and the Supervisor system of work; further enhanced supplier management, supplier development responsibility for quality checking approaches. Currently, the company has become the first by CNR IRIS management system certification audit of the company.
Fourth, the whole operation to improve staff skills. The company continues to operate direct employees engaged in production, to introduce product-focused, process requirements, quality standards, methods of operation as the basic content to full training, full assessment, certificates as the basic process of carrying out operations staff ” Great Training Great Training “activities and implement the system operator certificates. The goal is gradually to pre-training, certificates and quality system of a complete wage an effective mechanism. December 2009, the company’s 108 employees process more than 500 employees received the first batch of qualification certificates.
It is reported that the company has successfully developed China’s most powerful permanent magnet 3-megawatt wind turbine, doubly fed wind power master converter core technology, foreign technology to break the monopoly of this market and realized the sales income of zero breakthrough.

According to stall the propeller-type moment fans and variable speed constant frequency pitch moment characteristics of the fan, the domestic current installed capacity of the motor are generally divided into two categories:
1, asynchronous

(1) cage asynchronous generator; power 600/125kW 750kW 800kW 12500kW
The stator to the wind power generators grid with different power 50Hz AC;
(2) winding double-fed induction generator; power 1500kW
50Hz AC wind generators transmission to the stator, rotor control by the inverter to the grid or indirect active transport reactive power.
2, synchronous

(1) permanent magnet synchronous generator; power of 750kW 1200kW 1500kW magnetic field generated by the permanent magnet, the stator output by the full power rectifier inverter to the power grid after the 50Hz AC
(2) electrical excited synchronous generator; received from the external rotor DC current creates a magnetic field on the stator by the full power rectifier inverter output to the power grid after the 50Hz AC
According to the different leaf forms, the existing wind turbines are divided into the following categories:
3, the horizontal axis

Currently the world’s most widely used form of 5MW power around the maximum.
4, vertical axis

The early 21st century from China, Japan, Europe almost simultaneously invented a new type of wind turbine is different from the first vertical axis wind turbine (Darieu type), more efficient than horizontal axis wind generators, no noise and steering institutions, and simple maintenance. U.S. and European markets have become the preferred medium and small wind turbines. The world’s biggest power mode by the Shanghai Electronic Equipment Co., Ltd. Sri Lanka (MUCE) production of 50 kW vertical wind turbines, Japan’s largest power of 30 kilowatts, the power in the Anglo-American countries produce 1 kilowatt to 10 kilowatt.

It is understood that the German production of wind power generation equipment, 75% exported to other countries. Despite the global economic crisis, the German wind power equipment industry is still in the world market to maintain a leading position.

German Wind Energy Association (BundesverbandWindenergie) that the current demand for the U.S. market plummeted, leading to the world this year, wind power equipment market decline. However, the situation will change next year. The Federation stressed that 75% of the export rate showed Germany’s wind power generator equipment in the world market popularity. China’s wind power equipment production is also quite large, but exports almost zero.

German Machinery Manufacturers Association (VDMA) energy branch to the information provided, the first half of this year, Germany installed a total of 332 sets of wind power generation equipment, installed capacity of 660 MW. The branch head Helldan (ThorstenHerdan) said that this year the German wind generators installed capacity is expected to reach 27,600 MW, although growth was slower than last year’s level, but two years ago, the German federal government’s forecast is to 2020, installed capacity will reach 27,000 MW. It is estimated that in 2011 the industry can achieve the double-digit growth rates.

Germany’s Siemens Power Generation Group in the sea area of large-scale wind energy is the world’s leading companies. The company’s environmental and new energy business unit’s sales have accounted for one-third of total sales. Over the past 3 months, Siemens has been valued at 23 billion euros of orders, order offshore wind power generation equipment. In addition, land-based power network-related wind turbines equipment orders orders. Siemens CEO Peter Löscher (PeterLoeschler) said Road, the green technology in particular, so popular today.

Siemens addition to the Department of Energy outside the traditional industrial sector out of the shadow of economic crisis. It is reported that the total firm orders for 22% more than last year, including orders for Siemens China increased by 35%, Germany and even increase orders by 45%. Löscher, this shows that the world economy is steadily recovering.

2009, new wind power generator capacity in China 25100MW, is more than double the 2008 12100MW. iSuppli’s figures, last year about the world’s new small wind turbines capacity of one third, and the last five years of sustained development of China over Spain in 2009, becoming the world’s third wind power to provide land. Three years ago, the Chinese wind power capacity worldwide is only ranked 10, power generation capacity is 6100MW.

China wind power market received strong support from local procurement rules. China Development and Reform Commission, particularly the provisions of the domestic wind power equipment procurement rate of 70% can be allowed to build.

Under the influence of the policy, the current account of domestic new orders for wind turbines more than 76%, while China’s total wind power accounted for 62% of the market. iSuppli’s figures show a total of view, in 2009 several of the largest wind power companies – in the Division Uno, Goldwind Science and Technology and the DEC, 55% of the market. In addition, the next three years, will produce 900 million U.S. dollars annually over the field associated with the new business.
