Wind turbines operate in a natural environment, so their fatigue life depends on the characteristics of wind flowing into the wind turbine. Among the wind characteristics, turbulence intensity may vary depending on the location of the wind turbine, resulting in differences in the fatigue life even for wind turbines located at the same wind farm. On the other hand, it is important for safe, secure, and efficient wind turbine operation to understand the fatigue life of each wind turbine in detail and to take countermeasures. To address this issue, we have developed a technology that combines analysis of data accumulated in wind turbines and a load analysis method to accurately evaluate the expected life of each wind turbine in a wind farm. This report outlines the developed technology.
