Foreign object damaged compressor blades with nicks, dents and cracks can be ground into the smooth curved cutouts to reduce the stress intensification and stress concentration with a high speed grinding wheel. In doing so, depending on the extent and type of damage, designer has a requirement to estimate size and shape of the cut-out to be

Top 3 Types of Wind Turbine Failure

The generator in a wind turbine is responsible for creating the electricity by converting mechanical energy into electrical energy. When the generator fails, no power is produced, costing the wind farm operator valuable revenue. There are several reasons why the generator can fail, including wind loading, weather extremes, and thermal cycling.

6 FAQs about [Foreign objects fall into the wind turbine]

What causes a wind turbine to pockmark?

Depending on location, some turbines are more prone than others to impact from foreign objects. Golf balls are a surprisingly common culprit of ‘pockmarking’, as are a wide variety of falling or windblown objects, while a bird strike can put a serious dent in proceedings. There are also ‘acts of God’ to contend with, such as lightning strikes.

Did a wind turbine tower collapse during a typhoon?

Despite the fact that the wind turbine tower did not collapse, it had to be demolished for reasons of security. During typhoons, collateral objects such as trees, birds, and stones may also collide with wind turbine towers, but the collisions of these objects are typically less severe.

What causes wind turbine damage?

Investigating the damage cases reveals the key causes of damage to wind turbines from 2007 to 2017 and the frequency of their occurrence. Most wind turbine collapses were caused by structural failure of the turbine. However, wind turbine blade failure was also critical in many wind turbine collapses.

Are wind farms dangerous?

Several risks in wind farms are similar to those observed in other industries (Webster et al., 2013). Incident data to date has shown that the most frequent injuries relate to falling objects, particularly during the installation of turbines, as well as the risks of working at height across the life of a turbine (Aneziris et al., 2016).

Why do wind turbines collapse?

A review of wind turbine collapses indicated that strong winds are one major cause of wind turbine collapse. However, wind turbines are designed to activate protection mechanisms in a storm environment to reduce damage by strong winds. This section analyzes the forces that are sustained by wind turbines and the aforementioned protective mechanisms.
