摘要
风力发电机组功率曲线是考核机组性能的一项重要指标,但在实际操作过程中,由于现场自然风风速、风向变化的不确定性,给准确测取风力发电机组功率曲线带来困难。因此,借助空气动力学理论,提出一种简便求取风力发电机功率曲线的方法:利用机组计算机自身绘制的功率曲线,通过理论计算,对功率曲线进行风速和空气密度的修正,以提高功率曲线的精确度和可比性。
The power curve of wind generating set is one of the most important indicators to evaluate the units performance. But in actual operation, because of the uncertainty of natural wind speed and wind direction change on site, it is difficult to exactly measure the power curve of wind generating set. Therefore, by the aerodynamic theory, an easy approach to acquire the power curve of wind generating set is brought up： by use of the computer unit＇s own power curve drawn and through the theoretical calculation, the wind speed and air density of the power curve is modified, which improve the power curve of the accuracy and comparability.
