RESEARCH ON HYDRODYNAMIC CHARACTERISTICS OF WIND TURBINE WITH HEAVE PLATE UNDER WIND AND WAVE COUPLING
Research on an edge type heave plate to improve the hydrodynamic characteristics of the unit and stability of the unit.In the study,taking an 5 MW-CSC floating wind turbine as object,the overall dynamic responses under multiple parameters of edge heave plate widths and thicknesses were calculated utilizing by AQWA and FAST.On the basis,the characteristics were compared.The study show that,it has significant effect on peak RAO and frequency when changing the structural parameters of heave plate,while the influence on the surge RAO as well as frequency is relatively small.For the given model,further research finds that the stability performance is optimal when the width and thickness of the heave plate are in the range of 3 m and 1 m,respectively.The article provides a reference method for the design of floating wind turbine inclusive with heavy plate damping structure.
