摘　　要：基于对风电功率波动特性的分析,提出基于周期图及自相关函数的方法来描述风电功率周期波动特性。利用所提出的指标对吉林省2个风电场的实测风电功率数据进行的分析表明风电功率中存在周期性分量,但不同时间段不同风电场的周期性分量存在程度上的不同。通过与风电功率实时预测效果的对比表明本文所提方法是有效的。It has great significance to portray wind power fluctuations characteristic for the utilization of large-scale developments. This paper analyzes the characteristics of wind power fluctuations, and a method is proposed based on period gram and autocorrelation coefficient for wind power. Taking the measured wind power data from two wind farms in Jilin Province as example, we perform the analysis using above method, and it shown that there exist a periodicity component in wind power, but the existence of periodicity component is different for different time and wind farm. By contrast with the real-time prediction of wind power shows that the proposed method is effective.
