Turbulent and gusty wind conditions can cause generator overspeed peaks to exceed a threshold that then lead to wind turbine shutdowns, which then decrease the energy production of the wind turbines. We derive so-called “gust measures” that predict when generator overspeed peaks may occur.
ing generator overspeed thresholds that would lead to turbine shutdown events. The open-source wind turbine simulation tool OpenFAST. To increase the realism of the strator of a novel extreme-scale, two-bladed, downwind rotor design. In recent years, wind energy has seen rapid growth in adoption across the world.
Particular gust patterns in wind have been observed to cause overspeed peaks in the generator speed response.4–6 Generator overspeeding can be detrimental if it exceeds the turbine's overspeed shutdown threshold which can increase downtime and reduce the annualized energy production (AEP).
Wind Energy published by John Wiley & Sons Ltd. Wind Energy. 2024;27:1188 1204. The overwhelming proportion of wind turbines currently in operation are three-bladed upwind turbines, having a symmetrical configuration of three blades, 120 apart, with the rotor facing the wind and the nacelle and tower in its wake.
We primarily study the power curve, the flapwise blade loads, the generator speed, and actuator responses. We observe that particular gust patterns in near- and above-rated wind
