Applicability of Dynamic Inflow Models of HAWT in Yawed Flow Conditions

open access: yesEnergies, 2022
Horizontal axis wind turbines (HAWTs) experience yaw misalignments due to the physical limitations of yaw controllers and various novel active yaw controls. Moreover, the motion of floating offshore wind turbines (FOWTs) accelerates yaw misalignment. The

Fundamental study on yaw resonance mode (Change in yaw resonance mode depending on vehicle speed)

open access: yesNihon Kikai Gakkai ronbunshu, 2021
This paper starts with describing a method of deriving the resonance mode of a pendulum utilizing its equation of motion. Its resonance mode is that the particle accelerates toward the equilibrium position in the vertical plane including its fixed point.
