The worldĄŻs wind power industry has developed rapidly
In recent years, the worldĄŻs wind power industry has developed rapidly, the wind power industry, key technologies become more sophisticated, stand-alone capacity of 5MW wind turbine on land, semi-direct drive wind turbine started, direct-drive wind turbines manufacturers has been widely applied, the current mainstream of the international wind turbine has reached the 2.5-3MW, uses a pitch speed of mainstream technology, Europe has installed 3.6MW wind turbine volume, the United States has successfully developed 7MW wind turbine, and the United Kingdom is developing a giant wind turbine; European scale offshore wind power construction and related start of the layout grid, and wind conditions in the knowledge-based product analysis tools, machine tools and engineering design consulting services, has a clear international competitive advantage. Throughout the development status of the worldĄŻs wind power industry, wind power technology will show the following trends: development of more advanced air conditions analysis system; to develop large-capacity, high reliability, low cost wind turbine as well as lightweight, highly reliable offshore wind turbine; Wind onshore wind power generation will be based, and is actively expanding offshore wind power.
The real development of wind generators industry began in 1973 oil crisis, the United States, Western Europe and other developed countries seeking alternatives to fossil fuel energy, put a lot of money, with new technology development of modern wind turbines, the eighties started to build wind farm demonstration , a new power grid. In recent years, wind power development is expected to continue beyond its pace of development. In 2010, the worldĄŻs total wind power installed capacity of 196630MW, an increase of 24%, growth slowed down. Additional capacity on the global perspective, since 1999, starting with significant increases each year to add capacity, new 1999 Global wind power installed capacity of 4033MW, the rate of increase up to 84% in 2008 and 2009, new wind power installed capacity reached 27261MW and 38312MW, the growth rate were 38% and 41%. The new 2010 world wind power installed capacity of 37642MW, down 2%.
