Abstract The experimental testing of a Tension Leg Platform (TLP) floating wind turbine at 1:60 scale in wind and waves with a pitch-regulated 10 MW wind turbine is presented. The floating wind turbine was tested with three different control configurations: two closed-loop controllers and one open-loop controller. The experimental setup and program is described in this paper, and system identification and the responses of the floater to hydrodynamic loading are analysed and compared for the different control strategies. It was observed that negative aerodynamic damping for the onshore controller resulted in high oscillations in blade pitch, yielding an increased response in surge for all wave types. It was also observed that the surge motion governed the mooring line tensions, thus the onshore controller yielded the highest tensions in the front mooring line. Further the shutdown cases of the offshore controller led to larger surge displacement when the shutdown was initialized right before the wave impact.

不同控制策略下DTU10MW TLP浮式风力发电机的比例试验分析

摘要 介绍了具有 10 MW 变桨距风力发电机的张力腿平台 (TLP) 浮动风力发电机在风浪中以 1:60 比例进行的实验测试。浮动风力涡轮机使用三种不同的控制配置进行测试：两个闭环控制器和一个开环控制器。本文描述了实验设置和程序，并针对不同的控制策略分析和比较了系统识别和浮子对水动力载荷的响应。据观察，陆上控制器的负气动阻尼导致叶片桨距的高振荡，从而对所有波浪类型产生增加的喘振响应。还观察到浪涌运动控制了系泊索的张力，因此，陆上控制器在前系泊绳中产生了最高的张力。此外，海上控制器的关闭案例导致在波浪冲击之前立即启动关闭时更大的浪涌位移。
