4 Frequently Asked Questions about "Broken blades at a wind power plant"

What causes wind turbine blade damage?

A common conclusion from the evaluation of potential causes of wind turbine blade damage is the ultimate significance of the surrounding environment and the existing weather conditions. The appropriate selection of a wind park's installation site and the adequate siting of the wind turbines can eliminate induced fatigue loads.

How are wind turbine blade failure mechanisms analyzed?

Generally, failure mechanisms of wind turbine blades are analyzed using the following main methods: Computational modelling of blade deformation and damage. Post-mortem analysis of failed or damaged blades (either test blades or blades taken from old or damaged wind turbines) is the most obvious approach to explore the blade failure mechanisms.

How critical is a wind turbine blade to a damage mechanism?

The criticality of the wind turbine blade to a damage mechanism is primarily influence by its location within the blade, as illustrated in the top schematic of Fig. 8 . The leading edge is the area subject to highest loads wherein intermediate ones can be seen in the transitional regions from the cylinder to the aerofoil and plydrop.

Do wind turbine blades fail?

In general, although structural failures of wind turbine blades are rather rare, they do occur. The Caithness Wind Farm Information Forum (CWIF), an organization dedicated to halting the spread of wind turbines in the Caithness area of Scotland, tracks all publicly known wind turbine accidents worldwide.
