Wind Turbine Technology Transfer (Dongfang Turbine Co., Ltd.)

Abstract Dongfang Turbine Co., Ltd. and Austria AMSC Windtec company establish the partnership for the design and development of 2.5MW wind turbines jointly, and all the intellectual property rights is owned by Dongfang Turbine Co., Ltd. The WTGS uses double-fed asynchronous generator, in cooperation with speeding up gear box, delivering the power of high quality to the grid through the transformer. To adapt to the environment in China, the normal temperature and low temperature units were designed respectively. And to adapt to different wind zones, the units adapted toⅡ and Ⅲ wind zones were designed respectively. Currently, the prototypes have been developed and are being installed and preparing for commissioning at Zhangbei Testing Wind Farm in Hebei.

Wind Turbine Technology Transfer (Shanghai Electric Wind Power Equipment Co., Ltd.)

Abstract Through the project, Shanghai Electric Wind Power Equipment Co., Ltd. introducted the German Aerodyn 2MW wind turbine technology to manufacture a 2MW prototype installed at Dafeng wind farm in Jiangsu and intergrated to grid on April 18, 2009. The wind turbine meets the design requirements and passes the “type approval”. On the basis of digesting and absorpting the 2MW wind turbine imported technology, Shanghai Electric has developed its own types of the intertidal wind turbine, low temperature wind turbine and offshore wind turbine, which were installed at the Jiangsu Rudong Wind Farm, Jilin Siping Wind Farm and Jiangsu Xiangshui Wind Farm.

Wind Turbines Made in China or Made by China

Abstract China, a country with one of the world’s largest wind energy potentials, has seen tremendous growth in its wind power development in recent years. Yet Chinese manufacturers are still struggling to break into their own nation’s lucrative wind turbine industry. In 2005, domestic companies accounted for only 23 percent of China’s cumulative installed turbine market. The remainder of the production was dominated by foreign wind turbine giants, including Spain’s Gamesa, Denmark’s Vestas, and Germany’s Nordex.

Joint Memorandum on Realising the Opportunity and Potential of the Chinese Wind Market 2007

Abstract In the past, China has typically met its increased demands for electricity by burning more coal, but this has had very serious environmental consequences. The country has abundant wind resources, and the environmental benefits of utilizing this renewable resource are likely to be considerable. In order to spur its development, it has been proposed that the wind resource be treated much like oil or natural gas—and that Wind Resource Concessions (WRC) be established and granted to developers offering the most attractive bidding prices. This report addresses the potential use of the WRC approach within China. Both the conventional energy business and renewable energy business are affected by WRC. Their concerns are described, and the single most problematic aspect of wind power development—its high cost with respect to alternatives—is then addressed. Wind power will require governmental support, and this report describes potential policy approaches for providing such support, and for developing
