中文摘要：
为了掌握风力发电机控制策略对运行过程中风力发电机转速和功率流动的影响，在简要介绍与功率和转速变化有关的风力发电机控制策略的基础上，分析了采用不同控制策略的风力发电机功率产生的特点。重点阐释了风力发电机变桨矩控制方法对风力发电机组的功率流动、叶轮转速变化的影响。得出了不同控制策略下风力发电机功率流动方向、叶轮转速大小和方向的变化，以及叶轮转速变化的依据和限制。
英文摘要：
In order to grapple with the influence of the control strategy of wind-driven generation unit on the rotating speed and power flow, on the basis of the introduction of the control strategy that related to the power and variation of rotating speed, the features of power generation of wind driven unit under different control strategies is analyzed. The influence of control method for pitch on power flowing and rotating speed of the vane are focused. The direction of power flowing, variation of rotating speed and direction of the vane, and the criteria and restrictions of the variation are derived under different control strategy.
