摘要
海上风电场的设计水深逐渐增加,风机功率不断提高,传统的固定式基础不再适用,性能优良的浮式基础已成为研究的热点。针对60m水深,为600kW水平轴风机设计半潜式基础和系泊系统。运用SESAM软件建立半潜式风电平台的有限元模型,分别计算其频域和时域运动响应,分析其运动性能和系泊缆张力,对海上浮式风电场的开发具有一定的指导意义。
With the water depth of offshore wind farm and the power of wind turbine increasing gradually, the traditional fixed foundations are not applicable. The floating foundations with excellent characteristics have become a research focus. The semi-submersible foundation and mooring system are designed for a 600 kW wind turbine with a horizontal shaft, and the water depth is 60 m. SESAM software is used to establish the finite element model of this semi-submersible platform. The motion responses are calculated in both frequency domain and time domain. Motion performance and mooring line tension are also investigated. This research has some guiding values for the develop- ment of offshore wind farm with floating foundation.
