漂浮式风力机平稳运行是海上风电场建设的基本要求。为对比调谐质量阻尼器（TMD）对不同漂浮式风力机稳定性的控制效果，选取驳船型（Barge型）、浮柱型（Spar型）及半潜型（Semi型）3种漂浮式风力机，在机舱中配置TMD进行控制，研究3种漂浮式风力机在风、浪及流载荷联合作用下的稳定性控制效果。结果表明：无TMD控制时，Barge型漂浮式风力机响应幅度远大于Spar型和Semi型漂浮式风力机；TMD控制后，Barge型漂浮式风力机的响应大幅度减小，在平台首摇和塔顶左右方向上，分别接近Spar型和Semi型漂浮式风力机；TMD对不同类型的漂浮式风力机控制效果不同，Barge型漂浮式风力机控制的效果最好，其次是Spar型，Semi型控制效果最差。研究结果可以为漂浮式风力机的设计和开发提供理论参考。
Abstract
Steady operation of floating wind turbines is a basic requirement for construction of offshore wind farms.Here, in order to compare control effects of tuned mass dampers (TMDs) on stability of different floating wind turbines, three kinds of floating wind turbine were chosen including barge type, spar one and semi-submersible one.TMDs were configured in turbines’ cabin for control.TMD’s control effects on stability of three kinds of floating wind turbine under combination action of wind, wave and flow loads were studied.The results showed that without TMD control, barge-type floating wind turbine has a much larger response amplitude than those of spar-type and semi-type ones; with TMD control, barge-type floating wind turbine’s response is greatly reduced, in platform head yaw direction and tower top left-to-right one, barge-type floating wind turbine’s responses are close to those of spar-type and semi-type ones, respectively; TMD has different control effects on different types of floating wind turbine, TMD has the best control effect on barge-type floating wind turbine, followed by spar type and semi-type ones; the study results can provide a theoretical reference for design and development of floating wind turbines.
