摘要
以5 MW-CSC漂浮式风电机组为研究对象,联立AQWA与FAST对比分析多种边锋垂荡板宽度、厚度对整机动力响应的影响,并进行特性对比.结果表明,垂荡板结构参数对漂浮式风电机组垂荡与纵摇的峰值RAO以及频率影响显著,对纵荡RAO及频率的影响较小.针对给定机型,发现垂荡板宽厚分别在3 m和1 m区间时机组稳定性能最优.
Abstract
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.
