摘要
采用GH Bladed软件对某3MW风电机组建立数学模型,讨论了大型双馈式变速变桨风电机组控制策略,阐明机组传动链的小阻尼特性。论述了在控制器中加入传动链阻尼环节的原理和方法,应用MAT-LAB进行系统仿真,通过发电机扭矩到低速轴扭矩的阶跃响应分析证明了传动链加阻的有效性。
The control strategies of double fed variable speed variable pitch wind turbine are discussed, which uses a 3MW wind turbine＇s model built by GH Bladed software. By coupled vibration analysis, the little damping feature of drive train is shown. The principle and method of drive train damping are stated to decrease the drive train oscillation. Using MATLAB simulation, the effectiveness of drive train damping is proved by the step response from generator torque to low speed shaft torque.
