QINGHAI, July 27, SinoCast -- China has made breakthrough in wind power technology in Qinghai plateau area.

A research on wind turbine unit adaptive to Qinghai wind resource and grid-connected test just passed expert review, which fills in the gap of large vertical-axis wind turbine unit in China.

The wind turbine adopts large vertical-axis double-layer asymmetric airfoil H-shape structure and is equipped with high-strength composite blades and electromagnetic brake. Particularly, the 750kW vertical-axis wind turbine features lower install and maintenance cost and lower unit generation cost, which has been in grid-connected operation in Riyue Mountain wind farm and is ready for industrialization production.

The research has made applications for four utility model patents and four patents of invention with regard to core technologies in large structure of vertical-axis wind turbine. The utility model patents have been granted.

Qinghai is rich in wind energy but local wind power industry has been technologically restricted due to high altitude, low wind density and frequent changes in wind directions. The research will help improve Qinghai's wind power equipment manufacturing and extend wind energy industry chain.
