目前,深海的漂浮式风电已成为研究的热点,对海上浮式风力发电机而言,浮式结构比较重要。将研究重点放在深海型风机的浮漂平台及系泊系统上,基于深海型风力发电机组基础系统原理,研究设计了深海型风机整机建模,包括各主要部件坐标系的建立、主要部件建模的要求以及整机的拓扑结构图等。同时对漂浮平台进行了物理建模,采用四悬链系泊系统作用于方形漂浮平台的模型,分别对水平波浪力、竖直波浪力和斜向波浪力作用下的漂浮平台进行分析,得到同侧悬链与不同侧悬链的链端张力变化规律。

At present, the deep sea floating type wind power has become the hot researching field, for offshore floating wind turbines, the floating structure is more important. Thus, the focus of this paper is to study the deep sea type fan floating platform and the mooring system. Based on the principle of the deep sea wind turbine foundation system, the design for the modeling of the deep water fan type machine is given, which includes the establishment of the main components of the coordinate system, the main components modeling and topology structure of the machine. The physical modeling for the floating platform is established. By using the four catenary mooring systems on the square model of the floating platform, it is analyzed respectively that the floating platform under the different actions of the horizontal, the vertical and the diagonal wave forces, and the change rules for the chains tension of the ipsilateral catenary with the different lateral catenary are also given.
