准确模拟转子动态推力特性是漂浮式风电模型试验的难点,针对某大型漂浮式风电机组,采用一种基于无人机控制的漂浮式风电模型试验方法,通过微型风扇阵列实现风扇转速-气动载荷间的对应控制,有效复现转子的动态推力,并对不同方向的额定、极限以及瞬态停机等典型工况进行试验和数值仿真对比验证。结果表明：基于无人机控制的漂浮式模型试验方法能准确模拟转子动态推力特性,整机模型试验与数值仿真动力响应结果对比一致性较好,进而证明该试验方法相比传统叶片法能更准确反映转子动态推力特性,具有较好的应用前景。
Abstract
Accurately simulating the rotor dynamic thrust characteristics in floating wind power model tests presents a significant challenge. This study focuses on a large floating wind turbine and introduces a novel floating wind power model test method utilizing drone control. By employing a micro fan array, precise control over fan speed and corresponding aerodynamic loads is achieved. The method is applied to simulate and test typical operational conditions, including rated, extreme, and transient shutdown scenarios across various wind directions. The results demonstrate that the drone control-based model test method effectively captures the dynamic thrust characteristics at the turbine head and accurately replicates transient shutdown behaviors. The structural dynamic responses observed during testing are in good agreement with simulation predictions, confirming the reliability and reference value of the test data. Compared to traditional three-blade simulation approaches, this method offers superior accuracy in representing thrust dynamics and holds promising potential for future applications in floating wind turbine research and development.
