Technical FAQs 4

Can automated blade collision detection be used on wind turbines?

Abstract: This paper presents an automated blade collision detection system for use on wind turbines, toward the goal of supporting monitoring and quantitative assessment of wind energy impacts on wildlife.

What happens to wind turbine blades during service?

Wind turbine blades are subject to complex environmental and mechanical loading during their service time, including cyclic deformation, rain, sand and contaminants causing erosion, icing, high moisture and temperature variations, but also extraordinary events, such as transportation damage, lightning strikes and bird impacts [9–12].

What causes a wind turbine blade to collapse?

Structural Collapse and Buckling The structural collapse of a wind turbine blade can occur if the blade is subject to extreme loads, exceeds its designed strength, and/or as a result of degradation and fatigue of the blade elements, which reduce its structural strength, thus making it more susceptible to extreme winds.

Can a wind turbine blade be pulled from its hub?

As a result of root end failure, the blade can be pulled from its hub during the service time. Lee et al. reported that blade failures observed in the field at Eclipse and Ocotillo wind farm in 2013 were caused by pulling out the blades from the wind turbines due to delamination at the root.
