This paper addresses coupled wave and wind-induced motions of spar-type 5-MW wind turbines in harsh operational environmental conditions. Global dynamic motion responses have been analyzed by aero-hydro-servo-elastic time-domain simulations. The aerodynamics is based on an advanced blade element momentum theory. Panel method Morison formula accounting for the instantaneous position structure are applied hydrodynamics. Hydrodynamic drag considering geometrical updating introduce...
In this work, we propose numerical validations of the DeepCwind semi-submersible floating platform configuration for a single horizontal axis wind turbine using data from two experimental testing investigations. A Smoothed Particle Hydrodynamics solver is employed to estimate fluid induced loads, whereas mooring connections are handled via an external library. The first validation setup based on offshore concept moored with system taut-lines and tested free-decay surge heave motion...
ABSTRACT This study focuses on the dynamic responses of land‐based and floating wind turbines under blade pitch system fault emergency shutdown conditions. The NREL 5 MW turbine is studied. A hydraulic considered, faults are events with a seized or running out control. Emergency defined as fast pitch‐to‐feather maneuver blades. Load cases power production grid ensuing also analysed for comparison. scenarios blades' pitching activity simulated using HAWC2 through external Dynamic Link...
Proper performance of structures requires among other things that their failure probability is sufficiently small. This would imply design for survival in extreme conditions. The a system can occur when the ultimate strength exceeded (ultimate limit state (ULS)) or fatigue (fatigue state) exhausted. focus this paper on determination responses ULS checks, considering coupled wave and wind induced motion structural response harsh condition up to 14.4 m significant height 49 m/s 10 min average...
ABSTRACT This paper studies the drivetrain dynamics of a 750 kW spar‐type floating wind turbine (FWT). The studied is high‐speed generator, one‐stage planetary, two‐stage parallel and three‐point support type. response analysis carried out in two steps. First, global aero‐hydro‐elastic‐servo time‐domain analyses are performed using HAWC2. main shaft loads, which include axial forces, shear forces bending moments, obtained this integrated wind–wave analysis. These loads then used as inputs...
This article studies the feasibility of combining spar-type offshore wind turbine (inspired by Hywind) and a wave energy converter Wavestar) performing numerical simulations in operational conditions. The dynamic responses power production device are investigated for different power-take-off systems. Integrated/coupled aero-hydro-servo-elastic time-domain considering multi-bodies applied this paper. results show that choosing proper system, it is likely to minimize effects convertor on...
This paper deals with a novel concept by combining spar-type floating wind turbine (FWT) and Torus (donutshaped) point absorber-type wave energy converter (WEC) that is referred as the ‘Spar-Torus Combination’ (STC) herein. Concept feasibility study has been carried out doing numerical simulations. It showed STC results in positive synergy between generation terms of both capital investment power production. As concept, considered simple compact combination two technologies have had high...
The open-source code DualSPHysics, based on the Smoothed Particle Hydrodynamics method for solving fluid mechanics problems, defines a complete numerical environment simulating interaction of floating structures with ocean waves, and includes external libraries to simulate kinematic- dynamic-type restrictions. In this work, full validation SPH framework using experimental data available an test campaign 1:37-scale offshore wind turbine tension-leg platform (TLP) is presented. first set cases...
