Goldwind has successfully completed the installation of the wind LiDAR system ZephIR DM by Beijing New Energy Technology Ltd. on the company’s 6 MW prototype direct-drive, permanent-magnet wind turbine.
Goldwind confirms that the ZephIR LiDAR systems will be used for optimizing the prototype turbine before it enters mass production. The LiDAR system will measure power curves in an effort to further the understanding of the effects of wind flow propagation on the turbine’s performance.
Working with DNV GL, the 6 MW turbine will then be certified using ZephIR wind data before the program begins to focus on LiDAR-assisted control.
Both the turbine and the LiDAR are now operating at a test site in Dafeng, in China’s Jiangsu province, located on the country’s eastern coast. In March 2015, Goldwind decided to accelerate the pace of development of the 6 MW turbine, moving all funding to the Dafeng manufacturing base tasked with building the turbine.
The direct-drive machine, which has a rotor diameter of 150 meters, is the result of an upgrade from a previous 5 MW turbine development project.
