摘要
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. © 2019, Editorial Board of Acta Energiae Solaris Sinica.
