Wind turbines pass key tests

BEIJING - China's largest direct-drive wind turbine recently passed an international test meant to determine if it could continue operating even when there is a power dip on the national grid, announced the Sino-German maker of the device on Friday.

The 2.5-megawatt direct-drive permanent magnetic wind turbine, independently developed by Guangxi Yinhe Avantis Wind Power Co Ltd, recently passed a low-voltage ride-through test, said Lars Andreasen, general manager of the turbine maker in Beijing.

"This is so far the largest direct-drive permanent magnetic wind turbine in the world that has passed the test," Lars said.
