摘要
为了降低风浪联合作用下由漂浮式海上风机的平台垂荡运动和叶尖位移引起的载荷,以NREL-5MW基础风机和OC4-DeepCwind漂浮式平台为研究对象,提出了一种基于卡尔曼滤波算法的改进单神经元PI独立变桨距控制技术。通过OpenFAST-Matlab/Simulink联合仿真,结果表明:相较于PI统一变桨距和方位角权系数独立变桨距控制技术,提出的独立变桨距控制技术在一定程度上缓解了浮式平台的垂荡运动,降低了漂浮式海上风机叶尖位移的振幅。
To reduce the loads caused by the platform heave motion and tip displacement of floating offshore wind turbines under the combined action of wind and waves,taking the NREL-5 MW basic wind turbine and the OC4-DeepCwind floating platform as the research objects,an improved single-neuron PI independent pitch control technology based on Kalman filter algorithm is proposed.Through OpenFAST-Matlab/Simulink co-simulation,the results show that compared with the PI unified pitch and azimuth weight coefficient independent pitch control technology,the independent pitch control technology proposed in this paper alleviates the heave motion of the floating platform and reduces the amplitude of tip displacement for floating offshore wind turbines to a certain extent.
