摘　　要：随着海上风电向深远海发展,漂浮式风电机组凭借明显的成本优势得到广泛的重视。浮式平台是漂浮式风电机组的主要支撑部件。在波浪的作用下,浮式平台通常会产生大幅度的运动响应,严重影响风电机组的气动性能。加装垂荡板是常用的浮式平台控制方法,可以有效减少漂浮式风电机组的大幅运动。本文以自主设计的柱稳式半潜平台为研究对象,使用基于边界元(BEM)法的势流理论研究了垂荡板对半潜平台的水动力特性的影响。研究表明:垂荡板主要对垂荡和纵摇的附加质量影响最大。经过对垂荡和纵摇附加质量的归一化分析,表现出与频率的关联性下降的特性,可以使用归一化结果的均值来表征不同垂荡板半径对应的附加质量,这一结果可以为附加垂荡板的半潜平台的附加质量进行初步评估。As offshore wind power advances towards deeper and farther seas,floating wind turbines have garnered widespread attention due to their significant cost advantages.The floating platform is the main supporting component of floating wind turbines.Under the influence of waves,floating platforms usually exhibit large motion responses,which severely affect the aerodynamic performance of wind turbines.Adding heave plates is a common control method for floating platforms,which can effectively reduce the large motions of floating wind turbines.This work studies the influence of heave plates on the hydrodynamic characteristics of a semi-submersible platform,using a self-designed column-stabilized semi-submersible platform as the research object and employing potential flow theory based on the Boundary Element Method(BEM).The research findings indicate that heave plates mainly affect the added mass in heave and pitch.Through a normalization analysis of the added mass in heave and pitch,it is observed that the correlation decreases with frequency.The mean value of the normalized results can be used to represent the added mass corresponding to different heave plate radii.This result can provide a preliminary assessment of the added mass for semi submersible platforms with additional heave plates.
