摘　　要：基于定子磁场定向矢量控制理论,在dq轴同步旋转坐标系下,提出以定子侧功率因数作为主要观测和控制变量的励磁控制策略,建立了功率因数调节方程和励磁控制模型,分析了转子励磁参数变化对功率因数和输出功率的影响。理论分析表明,所提出的励磁控制技术对变速恒频双馈风力发电机控制系统设计和控制策略研究具有一定的参考价值。Based on the stator field oriented vector control theory and in the axis synchronous rotating coordinate system in the dq,proposed that using stator side power factor as the excitation control strategy of main observations and control variables,established the power factor adjustment equation and the excitation control model,and analyzed the impact of rotor excitation parameters variation on power factor and output power. Theoretical analysis indicated that the proposed excitation control technique has some reference value to the design of VSCF double fed wind generator and the study of control strategy.
