07 七 10 Global wind turbine giant intensified patent lawsuit
Currently, wind power generaotor is in the process of industrialization. U.S. Department of Energy released data show that the total U.S. wind power installed capacity of 2.47 MW from 1999 to 2009 of 34.86 MW. In 2007 to the end of 2009 these 3-year growth is particularly rapid, the additional capacity of nearly 2000 to 2006, 7 years to 3 times the additional capacity.
Since 2002, the U.S. patent issued over 800 wind turbine parts. Denmark’s Vestas Wind Systems, Germany 阿洛伊斯沃 this, Japan’s Mitsubishi Heavy Industries and General Electric are the United States holds the patent more than wind turbines. GE’s small wind turbines in which nearly 150 patents, came out top. General Electric is the largest U.S. supplier of wind turbines. According to the American Wind Energy Association estimates that in 2008 the U.S. General Electric wind turbines account for 43% of the market, and has more than 10 companies through licensing its patented technology. However, GE’s market dominance by Mitsubishi Heavy Industries challenges. Mitsubishi Heavy Industries in 2007, announced its 2.4 MW wind turbine units in the United States has received 411 orders. Alone order to close the nation’s total installed capacity by 2009 3 times. General Electric in early 2008 in the United States International Trade Commission (ITC) launched 337 proceedings, sued Mitsubishi for infringement of common wind turbine U.S. patent US5, 083,039; US6, 921,985, and US7, 321,221.
International Trade Commission in March 2008 filing, investigation. August 2009, the International Trade Commission administrative judge initially determined that Mitsubishi Heavy Industries and ’985 ’039 patent infringement, but did not infringe ’211 patent. However, the International Trade Commission’s unfair import investigations office Quedui administrative judge’s decision contended that General Electric Mitsubishi Heavy Industries, did not violate the patent, because General Electric is not in the United States of its patented technology, which does not meet under the Section 337 rule out the Mitsubishi wind turbine requirements.
January 8, 2010, the International Trade Commission’s six members of the Mitsubishi Heavy Industries of determination after review of the wind turbine generator does not infringe GE’s patents, without violating Section 337, so as to Mitsubishi 2.4 megawatt wind generators into the U.S. market exclusion a roadblock. However, General Electric, do not be to hand over the market, claiming to appeal the ruling of the International Trade Commission, and on February 11, 2010 Federal District Court in Texas alleging infringement of its U.S. patents Mitsubishi Heavy Industries, US6, 879,055 and US7, 629,705. In this regard, Mitsubishi Heavy Industries is not weakness, in the May 20, 2010 in the United States Court of Arkansas Western Federal antitrust suit against General Electric violations, abuse of patent litigation against competitors, threatening small wind turbine users. On the same day, Mitsubishi Heavy Industries is also in Central Florida to the Federal Court infringement lawsuit against General Electric, U.S. Patent US7, 452,185.

22 六 10 Gansu will build a fan-made full use of wind generators farms
A total installed capacity of 500,000 kilowatts, and all made large use of wind turbines is expected to open in July in the construction of Yumen.
Yumen Development and Reform Commission, according to the text introduces the main Rengao Sheng, the estimated total investment of 5 billion yuan, has been settled by the Yumen of several large wind power generator companies jointly funded and constructed. The proposed wind farm installed a 2 MW wind turbine-type, 2.5 MW, 3 MW and 5 MW fans, all for domestic small wind turbines equipment manufacturers.
Located in the Hexi Corridor of Jiuquan City, the state approved the first wind power generator base of 10 million kilowatts, which is the country under the jurisdiction of the Yumen 6 million kilowatts of wind power bases. As of May, Jiuquan wind generators installed capacity has more than three million kilowatts, of which Yumen 100 million kilowatts.
High Health Wen said that the construction of Gansu Province made large fan first demonstration project is to accelerate the pace of Jiuquan base construction of new energy to accelerate the marketing of domestic wind turbine speed.
This reporter learned that, after China’s large-scale wind farms rely mainly on the core components of the import fans. In recent years, domestic producers to speed up the process of domestic wind turbine. The full use of domestic equipment building large wind farms, is a fan made a test device.
High Health paper describes this new project is about to enter the real construction phase, expected to be completed by the end of 500,000 kilowatts installed capacity of the task. By then, Yumen will become the most complete fan type wind power base.

Small wind turbines trend of future development? We believe that should include the following:
1) The small wind turbine and solar cells as the most reasonable combination of the independent power supply can develop more applications, including wind and solar portable power, wind and solar water pumping systems, wind and solar aeration systems, wind and solar heating systems and so on. With the variety of products for small wind generators, wind and solar power supply system independent of municipal projects, in the border posts, in remote areas all have very broad application prospects.
2) The small wind turbine for power generation system
As we all know, Germany and Japan, photovoltaic solar roof plan for the development of the industry. However, resources in the UK and other poor countries, the sun, is promoting rooftop wind turbine power generation scheme. Small wind turbines installed in the home and power generation, can improve the power supply structure, is distributed renewable energy power generation ideal way.
At present, the domestic products of small fans to start the application of the British and other foreign tests, started going abroad. United Kingdom, the United States and other countries have legislation to encourage families to install small wind turbines and power generation systems and networks for small wind turbine applications in a great space for development.
However, home wind generators to promote the product in the family put forward higher requirements, low wind speed power generation, low noise, high reliability, aesthetics, security, and so have higher requirements.wind mini generators technical progress is the fundamental guarantee for the promotion of industrial development.
China’s wind power turbines industry, the development of small scale proposals
China’s small-scale wind turbine industry is technology-based and proprietary products are made of 100% and to guarantee the healthy development of industry, must:
1) setting up quality supervision system
Small wind turbine industry is being dragged down quality, and only perfect quality supervision system in order to prevent inferior products flooding the market in order to give industry a fair competition and healthy development of the environment.
2) government programs for small wind turbine to provide a promotional opportunity for product
“Send electricity to the villages,” project uses solar power systems, small wind machine in our country lost a promotion and development opportunities, hopes “to send electricity to the villages” project can be fully considered Wind Power Generation System for China’s Small Wind Turbine industry to provide a promotion and development opportunities.
3) concern about awind electric generators industry, technological progress
New energy industry in China, the wind generators is one of the few little difference between the level of foreign technology industry, if the industry can expand in international markets can become highly competitive products for China’s exports foreign exchange contribution. Hope relevant departments in China can our high reliability, high quality turbine generators products into the catalog of foreign aid.
