变速风力发电机组中塔架固有频率及叶轮旋转频率一致会致机组出现共振现象。为避免共振，设立转速禁区控制风力发电机组快速通过共振区间。在研究分析两种不同基于转速禁区控制策略基础上，提出适合两叶片风电机组避免塔架共振控制方案。通过 Bladed 软件仿真测试并分析不同转速禁区对机组性能影响，将所得参数用于现场实验。仿真、实验表明，所提转速禁区方案能有效避开共振区，并能保证发电量损失最小。

For variable-speed wind turbine (VSWT),resonance appears when the natural frequency of tower is close to the rotational frequency of rotor.In order to avoid resonance,a speed exclusion zone (SEZ)to control a wind turbine passing quickly through the zone was established.Two control strategies based on SEZ were analyzed and the suitable one for two-blade VSWT was proposed.The impacts of different SEZs on turbine performance were measured and analyzed through simulations with the Bladed software,and the parameters obtained were applied to field trials.The simulation and experimental results show that the proposed strategy can effectively avoid the arousal of tower resonance, and ensure the minimum loss of generation power.
