Michigan Blade Failure

Mi_blade_break1_thumb Another turbine failure has been reported at Michigan's Deerfield wind facility in Huron County. The Deerfield project includes a mix of Vestas V110 2MW and 2.2MW machines for a total installed capacity of 150 MW. Two blades on separate turbines broke in half in late 2016 when the project was in the process of being commissioned. There was “an anomaly in the manufacturing process that resulted in a cavity in the blade shell support structure where the blades broke,” Vestas told reNEWS. Fifty blades in the 72-turbine facility shared the same flaw. No information is available on the cause of this recent failure.

Out-of-control wind turbine ‘shook itself apart’ in Huron County

The turbine exceeded designed rotation speeds — 14.4 rpm (revolutions per minute) -- and at that speed, blade tips are moving at about 200 mph, according to Exelon. It created an imbalance as blades picked up speed. At the time of collapse, rotation speeds reached 18 rpm, officials said. “At that high of an rpm, the thing just basically shook itself apart.”
