Abstract
本发明公开了一种风力发电机变桨控制方法,包括以下步骤:1)判断机组是否出现外部差异变桨退出需求,是则进入步骤2),否则进入步骤3);2)判断风电机组差异变桨控制功能是否开启,是则采用纯协同变桨控制,否则进入步骤3);3)判断是否发电机转速大于差异变桨切入转速且桨距角小于差异变桨切出桨距角,是则差异变桨控制器保持满幅值输出;否则通过增益调度环来实现差异变桨控制器退出;各个桨叶的目标桨距角输出给变桨系统,执行变桨动作,最后差异变桨使能关闭且差异变桨控制器输出为0。本发明在纯协同变桨与差异变桨策略间进行协同调度控制,在非必要工况和停机过程下平滑关断差异变桨环,实现整个切换过程都不增加不平衡载荷。
The invention discloses a pitch control method for a wind turbine, comprising the following steps: 1) judging whether the wind turbine has an external differential pitch pitch exit requirement, if yes, it goes to step 2), otherwise, it goes to step 3); 2) judging the differential change of the wind turbine Whether the propeller control function is turned on, if yes, use pure cooperative pitch control, otherwise go to step 3); 3) Determine whether the generator speed is greater than the differential pitch cut-in speed and the pitch angle is smaller than the differential pitch cut-out pitch angle, then The differential pitch controller maintains the full amplitude output; otherwise, the differential pitch controller exits through the gain scheduling loop; the target pitch angle of each blade is output to the pitch system, the pitch action is performed, and finally the differential pitch is enabled off and the differential pitch controller output is 0. The present invention performs cooperative scheduling control between pure cooperative pitch and differential pitch strategies, smoothly shuts off the differential pitch ring under non-essential working conditions and shutdown processes, and realizes that the entire switching process does not increase unbalanced loads.
