How damaging is a typhoon to wind turbines?

Building wind turbines along the coast can reduce the likelihood of hurricanes forming. Severe turbulence during typhoons is often the main cause of wind turbine vibration failure. The intensity of turbulence reflects the pulsation characteristics of the wind. The higher the turbulence intensity value, the more destructive it is for the wind turbine. The formula for calculating the turbulence intensity I is the ratio between the standard deviation σ of the pulsating wind speed at a certain time interval and the average wind speed U. The higher the wind speed, the greater the turbulence is weak. However, when a typhoon hits, upper and lower convections are strong and extremely strong winds are accompanied by unpredictable turbulence. Disturbance of wind turbulence will produce random forced vibration on a flexible structural system such as a wind turbine, which will cause a fatal blow to the surface of the blades and the transmission system of the wind turbine.
