摘要
针对实际功率曲线与理论功率曲线在风速8~12m/s之间相差较大的情况,本文提出:通过提高额定转速或者提前变桨两种措施优化了功率曲线,减少了实际功率曲线与理论功率曲线的差距。同时通过对载荷的进一步分析,确认机组的强度不会受两种措施的影响,从而论证了这两种措施可行性,为功率曲线优化提供一种切实可行的方法。
Under large difference situation between the actual power curve and the theoretical power curve at wind speed from 8 to 12m/s,this paper puts forward:the gap between the actual power curve and the theoretical power curve has reduced by takeing the two kinds of measures,which improving the rated speed or changing the pitch in advance to optimize the power curve. Meanwhile,Through further analysis study on the load to confirm the strength of the unit will not be affected by this two kinds of measures,it demonstrates that the measures are feasibility,and it provides a feasible method for power curve optimization.
