S0503-5-4 Effects of Wind Characteristics in Complex Terrain on Wind Turbine Fatigue Load

Abstract

This paper shows results of aero-elastic on wind turbine fatigue load to clarify the effects of turbulence characteristics in complex terrain. The effects of turbulence intensity, longitudinal, lateral and normal component of turbulence standard deviation of wind speed fluctuations on the blade bending moment are compared. The results showed that the correction model of turbulence intensity for complex terrain described in the IEC 61400-1 is very conservative for normal operation mode.
