摘要
为研究垂荡板对漂浮式风力机Spar力机为研究对象,运用数值计算方法得出不同透空率垂荡板和在相同透空率下不同孔数垂荡板的水动力性能,并分析其频域和时域特性。结果表明,在相同孔数不同透空率垂荡板对比分析中,漂浮式风力机Spar为10%垂荡板作用下的稳定性最佳;选用透空率10%的垂荡板,对其进行不同开孔,并对8孔、12孔、16孔、20孔、24孔、28孔和32孔进行水动力特性分析对比,其中附有24孔垂荡板漂浮式风力机Spar平台的稳定性最好。
In order to investigate the influence of heave plates on floating wind turbine Spar platform hydrodynamic characteristics,the study focuses on 5 MW offshore wind turbine loaded by Umaine-Hywind Spar platform. By applying numerical methods,the hydrodynamic performances of heave plates with different vacancy rates and the same permeable rate in different numbers of holes are obtained. In addition,frequency domain and time domain characteristics are analyzed. In comparative study of heave plates with the same permeable rate in different numbers of holes,two results are showed. The first one is that the Spar platform has the best stability when the permeable rate is 10% The second one is,when choosing the heave plate with a permeable rate of 10% and opening different numbers of holes,includes 8,12,16,20,24,28 and 32 holes,the heave plate which has 24 holes owns the best stability.
