摘要
从浮式海上风电机组的全寿命设计角度出发,以此类风电机组便于安装、替换、维修和拆除为目标,提出了一种新型张力腿平台双模块浮式海上风电机组结构系统。基于BEM方法研究了采用该结构系统的海上风电机组的叶片的气动性能,并综合考虑了风电机组浮体模块和张力腿平台模块的多体机械耦合和水动力耦合效应。选取海上风电机组4种典型工作海况,将新型张力腿平台双模块浮式海上风电机组结构系统与常规张力腿平台单体浮式海上风电机组结构系统的主要动力响应特征进行了对比分析,揭示了该新型张力腿平台双模块浮式海上风电机组结构系统可以有效降低浮式海上风电机组平台的纵荡位移响应,对改善浮式海上风电机组的运行性能具有积极意义。此外,还对该双模块结构系统拆除风电机组的可行性进行了初步验证。
This article from the perspective of life-cycle design of floating offshore wind turbine,aming at the easy of installation,replacement,maintenance and removal ot such wind turbines,a new type of tension leg platform(TLP)dual-modules floating offshore wind turbine(FOWT)structure system is proposed.Based on BEM method,the aerodynamic performance of blades of offshore wind turbine using this structural system is studied,and the multi-body mechanical coupling and hydrodynamic coupling effects of wind turbine floating module and TLP module are comprehensively considered.The main dynamic response characteristics of new type of TLP dual-modules FOWT structure system and conventional TLP single FOWT structure system are compared and analyzed by selecting four typical working sea conditions of offshore wind turbines.It is revealed that the new type of TLP dual-modules FOWT structure system can effectively reduce the surge displacement response of FOWT platform,which is of positive significance to improve the operation performance of FOWT.In addition,the feasibility of removing the wind turbine in the dual-modules structure system is preliminarily verified.
