Multiple-degree-of-freedom actuation of rotor loads in model testing of floating wind turbines using cable-driven parallel robots
Chabaud, Valentin Bruno; Eliassen, Lene; Thys, Maxime; Sauder, Thomas Michel (Journal article; Peer reviewed, 2018)Model testing of offshore structures in ocean basins has been accepted as a necessary step for the validation and calibration of numerical models, as well as for final design checks in extreme environments. While offshore ... -
Power train degradation modelling for multi-objective active power control of wind farms
Khazaeli Moghadam, Farid; Chabaud, Valentin Bruno; Gao, Zhen; Chapaloglou, Spyridon (Journal article; Peer reviewed, 2023)With the coming installation of hundreds of GW of offshore wind power, penetration of the inherent power fluctuations into the electricity grid will become significant. Therefore, the use of wind farms as power reserve ... -
Real-time hybrid model testing of a braceless semi-submersible wind turbine. Part I: The hybrid approach
Sauder, Thomas Michel; Chabaud, Valentin Bruno; Thys, Maxime; Bachynski, Erin Elizabeth; Sæther, Lars Ove (Chapter; Peer reviewed, 2016)This article presents a method for performing Real-Time Hybrid Model testing (ReaTHM testing) of a floating wind turbine (FWT). The advantage of this method compared to the physical modelling of the wind in an ocean basin, ... -

The ReaTHM test method was used for ... -
Real-time hybrid model testing of floating wind turbines: sensitivity to limited actuation
Bachynski, Erin Elizabeth; Chabaud, Valentin Bruno; Sauder, Thomas Michel (Journal article; Peer reviewed, 2015)Real-time hybrid model testing (ReaTHM) is a new approach for conducting small-scale experimental campaign [1], [2] and [3]. In the case of a floating wind turbine in a wave basin, the aerodynamic loads on the wind turbine ... -
Rotor‐integrated modeling of wind turbine aerodynamics
Chabaud, Valentin Bruno (Peer reviewed; Journal article, 2021)A novel approach for the modeling of rotor-integrated aerodynamic loads is suggested to answer the need for a comprehensive, insightful, and analytical actuator disc model. All the six degrees of freedom (including tangential ... -
Yaw misalignment in powertrain degradation modeling for wind farm control in curtailed conditions
Khazaeli Moghadam, Farid; Gao, Zhen; Chabaud, Valentin Bruno; Chapaloglou, Spyridon (Peer reviewed; Journal article, 2024)A framework characterizing the degradation of wind turbines for use in multiple-input damage-aware farm control is suggested. The focus is on the fatigue damage of the powertrain (drivetrain + generator) system, but the ...
