海上浮式风力机及其动力学问题

Offshore Floating Wind Turbines and Related Dynamic Problems

深水风资源更为丰富,随着科技进步风电场正逐步向水深百米及以上的海域发展.针对海上浮式风力机、浮式基础以及系泊系统作业时,受到风浪流等的联合作用,就不同海上浮式风力机形式及其典型结构对应的气动载荷、水动力载荷,浮式风力机系统与环境动力的耦合问题、处理方法和可能的发展方向作了简要的评述.充分考虑作业背景的环境流场和风力机尺度,针对不同的流动特征综合各种理论方法和计算手段,更为准确地进行空气动力学-水动力学-控制系统-结构耦合分析是研究的难点和发展方向.

As one kind of green energy, ocean ~nd power is plentiful in deep sea, and more and more offshore wind power plants are being on to be constructed in the sea water of depths over one hundred meters. While the offshore floating wind turbine system was working, the wind turbine, floating foundation and mooring system will affect each other through coupling with wind, wave and current actions. The various offshore floating wind turbine systems and the corresponding environmental loads were briefly discussed. It was be a difficult key problem for the future to conduct comprehensive analysis of aerodynamic-hydrodynamic-service system~ structure for the coupling effects of the offshore floating wind turbine system and make full con- sideration of environmental flow field and dimension characteristics of the system structure, there for exploration and sythesis of suitable theories and approaches should be done in ad- vance.
