摘　　要：为解决传统永磁风电机组高电压穿越控制策略存在超速脱网风险问题,提出一种基于桨距角控制的高电压穿越控制策略。高电压穿越期间,首先,按照并网要求向电网提供无功支撑;其次,考虑转子转速限制,当转子转速达到参考值时启动桨距角控制,抑制转子转速上升;最后,通过仿真试验,验证了所提控制策略的有效性。基于桨距角控制的永磁风电机组高电压穿越控制策略,既能向电网提供无功支撑,又能避免超速脱网。To address the risk of overspeed and disconnection in traditional high voltage ride through control strategies for permanent magnet wind turbines,a high voltage ride through control strategy based on pitch angle control was proposed.During the high voltage ride through period,firstly,the reactive power support was provided to the grid according to grid connection requirements;secondly,considering the limitation of rotor speed,when the rotor speed reached the reference value,the pitch angle control was started up to suppress the increase of rotor speed;finally,the effectiveness of the proposed control strategy was verified through simulation experiments.Adopting a high voltage ride through control strategy based on pitch angle control for permanent magnet wind turbines,it can not only provide reactive power support to the power grid,but also avoid overspeed disconnection.
