大型风力发电机动态转矩阻尼控制器设计

摘要

从大型风力发电机运行的实际问题出发，针对由于传动链弱阻尼特性而存在的额定转矩附近转矩变化引起传动链谐振的问题，设计了基于快速傅里叶变换和数字滤波器技术的带有动态相角补偿功能的转矩阻尼控制器，成功抑制了传动链谐振，保证了风机的稳定运行。%From the point of view of practical problem in operation of large wind turbine, due to weak damping of drive chain, according to drive chain resonance problem caused by torque change in the vicinity of the rated torque, a dynamic torque damping controller for large wind turbine, which is based on fast Fourier transform and digital iflter technology with dynamic phase compensation has been designed. The dynamic torque damping controller can successfully restrain the resonance of drive-chain and keep the wind turbine operate stably.
