Bending moment characteristic analysis of utility-scale onshore …

When the wind speed reaches the cut-in wind speed and the wind turbine starts to run, EFL edge tends to be stable. In Fig. 24 (b), EFL edge increases with the increase of rotor speed generally. In addition, in most cases, EFL edge is higher than EFL flap, which indicates that fatigue damage is more likely to occur in the edgewise direction …
