浮子对正交化漂浮式风电场系泊系统影响研究
Research on the Influence of Buoy on Mooring System of Orthogonal Floating Wind Farm
摘要
Abstract
The stability of platform is the basis for ensuring the normal operation of the wind power system.In order to improve the stability of the wind turbine platform and reduce the risk of mooring failure,a 2×2 orthogonal array wind farm is constructed based on a 5 MW Barge platform.The stability of the platform mooring is improved by setting buoys in the wind field.Based on the radiation/diffraction theory and the finite element method,the effects of different buoy arrangements and their net buoyancy on the dynamic response,mooring tension and laid length of the platform in the wind farm are compared.The results show that the arrangement of buoys in the wind farm can significantly reduce the surge and sway dynamic response of the platform.It is preferable when the net buoyancy range of the buoys is 0.3～0.6 times the mooring weight of the overhanging section(0.3～0.6 G).The mooring tension decreases with the increase of buoyancy,and the length of mooring laid section increases first and then decreases with the increase of net buoyancy.When the buoys are not evenly arranged,with buoys being on the leeward side only,the sway,surge response and mooring tension of the platform on the windward side are smaller than those of the uniform arrangement.The length of the mooring lying section decreases with the increase of buoyancy,but the response of the platform on the leeward side is almost unchanged.Consequently,the buoys can effectively reduce the dynamic response of the platform in the wind farm and improve the mooring characteristics.Moreover,the net buoyancy on the windward side can be adjusted by adopting an unequal arrangement of net buoyancy according to the needs,so as to minimize the mooring tension.关键词
