摘　　要：研究一种大型风电机组塔架主动阻尼控制技术,基于对塔架顶部前后加速度的检测,在现有风电机组变桨控制环中新增一个塔架主动阻尼控制环,以实现增加塔架前后一阶模态的阻尼,进而能显著减轻机舱、塔架前后方向振动和塔架载荷。首先从理论上分析了塔架主动加阻控制基本原理,然后阐述塔架主动控制技术的控制规律及实现方案,再利用经典控制理论完成塔架主动阻尼器的设计。在GH Bladed软件中进行Windey 1.5MW-82机组的建模和塔架主动阻尼控制技术仿真研究,并在张北单晶河风场的一台1.5 MW机组上进行塔架主动阻尼控制技术现场试验,仿真结果和现场试验结果均验证了本塔架主动阻尼控制方案的合理性,且控制效果显著,具有实际推广应用价值。Active tower damping control for tower load reduction and tower vibration reduction on wind turbines was developed. A tower damping control loop is added on the pitch control loop of wind turbines for realization active tower damping control, which provides a direct measure of tower fore-aft acceleration. The principle, control law, and realization method of active tower damping control is developed, and the active tower damping controller is designed using linear control design techniques. As an example, a 1.5 MW wind turbine is simulated and analyzed in GH bladed software, and the field test of active tower damping control is carried out on a Windey 1.5MW-82 wind turbine which is in Zhangbei Dangjinghe farm. The results of simulation and field test verify that active tower damping control can effectively reduce tower load and tower vibration.
