摘　　要：鉴于风的不确定性、间歇性以及风电场内各机组间尾流的影响,针对第七届全国大学生电工数学建模竞赛A题的数据,通过"重标定域"方法对风电机组的风电功率的波动特性进行分析,计算了各机组的H值。结果表明,风电功率近似服从正态分布且具有负向反馈性,而风电功率波动幅度则取决于方差。Due to the uncertainty and intermittence of wind, and the wake effect of different units in the wind farm, the paper analyzes the wind power fluctuation characteristics and calculates H value for each unit through the method of ＂recalibration domain＂ according to the data from a set of questions of the Seventh National College Electrical and Mathematical Modeling Contest. The result shows that the wind power is similar to the normal distribution and has negative feedback, and the fluctuation range of wind power is determined by the variance.
