摘　　要：针对基于传统控制策略双馈风电机组高电压穿越存在超速脱网风险的问题,提出一种考虑桨距角控制的高电压穿越控制策略。高电压穿越期间,一方面通过控制风电机组为电网提供无功支撑;另一方面,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。仿真结果表明,与传统控制策略相比,所提控制策略可使双馈风电机组在兼顾对电网提供无功支撑和避免转子转速越限两个目标下实现高电压穿越。Aiming at the risk of over-speed and off-grid in the high voltage ride through of doubly fed wind turbines based on the traditional control strategy,a high voltage ride through control strategy considering the pitch angle control was proposed.During the high voltage ride through period,on the one hand,it provided reactive power support for the grid by controlling the wind turbine;on the other hand,when the rotor speed reached the reference value,the pitch angle control was started to inhibit the rotor speed rise.The simulation results show that compared with the traditional control strategy,the proposed control strategy can enable the doubly fed wind turbines to achieve high voltage ride through under the two objectives of providing reactive power support to the grid and avoiding rotor speed overrun.
