风电场一次调频控制策略研究

Research on Wind Farm Primary Frequency Control Strategy

提出了一种用于风力发电场输出有功功率调节的桨距角控制和转子转速控制方法,提高风力发电在扰动后参与电网频率恢复的能力。通过所提出的控制方案,风力发电场具有更高的灵活性,并且能够根据需要增加或减少输出功率,有助于电网频率恢复。最后,对几种控制方案进行测试,验证了在电网频率波动下的频率恢复能力。

A pitch angle control and rotor speed control for doubly-fed wind turbines are proposed.Improving the ability of wind power generation to participate in power grid frequency recovery after disturbance.Through the proposed control scheme,the wind farm has higher flexibility,and can increase or reduce output power according to demand,which is conducive to grid frequency recovery.Finally,some kinds of control schemes are tested to verify the ability of frequency recovery under frequency fluctuation.
